March 14, 2019

Despite government claims, radiation from the 2011 nuclear disaster is not gone.

Fukushima, on the other hand, is dealing with the release of radionuclides, which are fission products from nuclear power plants. These radionuclides are not rays, but dust-like particles that can stick to the body and be inhaled or ingested. Weather factors like wind and rain have displaced many radionuclides like cesium-137, which accumulate in patchy locations, such as ditches, drainage areas, or playgrounds. Because of this uneven dispersion, monitoring posts often overlook the presence of hot spots, places where the level of radiation is significantly greater. Dissatisfied by state-sponsored monitoring, many citizen scientists have collectively tracked and monitored residual radioactivity in Japan, legitimizing the presence of hot spots.

To measure radiation levels in Fukushima, the Japanese government has installed monitoring posts that display the current atmospheric level of radiation on an electronic board. Measurements of radiation levels in the air are taken at different locations and compiled to create an average level of radiation for the cities of Fukushima.

Monitoring posts are also strategically placed and their surrounding areas cleaned so that the levels of radiation remain lower. No monitoring posts are present in forests and mountains, which represent more than 70 percent of the area of Fukushima prefecture.

On top of such problems, radiation posts only measure radiation in the form of gamma rays. Yet the disaster has also released radionuclides that emit ionized particles, that is, alpha and beta particles. These ionized particles are not taken into account by state monitoring posts, even though they are dangerous if inhaled or ingested. Consequently, the data accumulated by monitoring posts is partial and unrepresentative of the extent of radioactive contamination.

Levels of radiation have also decreased due to a massive state-sponsored program of radioactive decontamination in the urban and rural areas of Fukushima. The process of decontamination consists of collecting and removing radioactive pollutants. Radionuclides are then contained in vinyl bags, so as to impede the risk of rescattering residual radioactivity. As a testament of the government-led decontamination, mountains of black plastic bags, filled with contaminated soil or debris, can be seen in many parts of Fukushima, forming a stark contrast against the emerald-green mountains of the region.

As such, decontamination does not imply that radiation has vanished; it has simply been moved elsewhere. Yet in rural regions, where many of the bags are currently being disposed, far away from the eyes of urban dwellers, residents are still forced to live near the storage sites. Many rural residents have criticized the actual efficacy of the decontamination projects. For instance, vinyl bags are now starting to break down due to the build-up of gas released by rotten soil. Plants and flowers have also started to grow inside the bags, in the process tearing them apart. With weather factors, residual radioactivity inside the bags will eventually be scattered back into the environment.

In the end, state-sponsored monitoring and decontamination are remedial measures that manage the perception of radiation in the environment. However, this does not imply that radioactive contamination is gone – not at all. When we look at the official maps of radiation of northeastern Japan, levels are low, but there are many ways to make them appear low. With overall lifespan that exceeds hundreds of years, radionuclides like cesium-137 or strontium-90 will continue to pose a problem for decades to come. However, with the upcoming 2020 Tokyo Olympics, it is doubtful that the Japanese state will ever acknowledge this reality.

Congenital heart disease operations rose 14% after Fukushima nuclear accident

March 13, 2019

Murase K, et al. J Am Heart Assoc. 2019;doi:10.1161/JAHA.118.009486.

There was an increase in the number of operations performed on neonates and infants with complex congenital heart disease after the 2011 Japanese earthquake and tsunami that resulted in a nuclear accident at Fukushima, according to a study published in the Journal of the American Heart Association.

Although this research focuses on events that occurred in Japan, the potential for nuclear accidents throughout the world is a global health concern,” Kaori Murase, PhD, associate professor at Nagoya City University in Japan, said in a press release. “Our study suggests that a nuclear accident might increase the risk for complex congenital heart disease.”

Researchers analyzed data from annual surveys conducted between 2007 and 2014 by the Japanese Association for Thoracic Surgery. The years that were included in the survey were the 4 years before and after the Japanese earthquake on March 11, 2011. The surveys included information on 45 surgical classifications for congenital heart disease. Patients with congenital heart disease were categorized into two groups based on the time of occurrence during heart development, complexity and the age at operation.

There was a 14.2% increase in the number of operations per 100,000 live births for complex congenital heart disease in neonates and infants. There was no significant change in the number of operations performs in patients aged 1 to 17 years.

The cause of the increase is unknown, but we should consider the influence of the radionuclides emitted from the Fukushima nuclear power plant,” Murase and colleagues wrote. “More specific patient data such as time, location and amount of maternal exposure would be required to determine the cause.” – by Darlene Dobkowski

Teaching about radiation after Fukushima

Figure-2-1024x768.jpgAn interactive model at the Decontamination Info Plaza in the city of Fukushima allows visitors to “decontaminate” a house and yard.

At the entrance to the Fukushima Prefectural Centre for Environmental Creation, a friendly hippopotamus-like mascot welcomes visitors while accepting hugs from children. Buzzing with young families, this government-sponsored scientific hub was created to explain the phenomenon of radiation to the population of Fukushima, the victims of the eponymous 2011 nuclear disaster.
 
Inside the main annex, an interactive model explains how external radiation exposure can be lowered. Visitors are encouraged to increase their distance from a radiation-emitting device while making use of shielding, thereby lowering their overall exposure. In another corner, children are learning about the radioactive isotopes released during the disaster, although representations of these perils are anything but threatening. Using posters and comic books, radionuclides such as plutonium‑239 and cesium‑137 are represented as adorable anthropomorphic figures. Each radionuclide has its own characteristics, such as pronounced eyebrows or a distinctive hairstyle. There is no discussion about how exposure to these radionuclides can cause serious bodily harm—an increased risk of cancer, for example.
 
In the aftermath of the Fukushima meltdowns, which triggered a released of radioactive pollutants, the Japanese state initially decided to increase the mandatory evacuation trigger from 1 millisievert of radiation exposure per year to 20 millisieverts per year. In other words, the public was forced to accept a new threshold of safety. While this policy caused much scientific and public controversy, 20 millisieverts per year remains the benchmark for what is considered safe in Fukushima. Places like the Centre for Environmental Creation downplay the controversy of a raised threshold of exposure.
 
Situated in the town of Miharu and opened in July 2016, the center was established by the prefecture of Fukushima, with the financial support of the Japanese government, to conduct research and provide education on radioactive contamination. The center is one of several government-sponsored revitalization projects aimed at rebuilding the trust of people living in Fukushima. Mostly visited by young families, it represents a new approach to risk communication. As a technical advisor explained to me, this approach aims to “deepen the understanding of children about radiation” by allowing visitors to experience information firsthand through interactive games, fun activities, and cute presentations.
 
Past efforts to present nuclear science in appealing ways have often blended education with propaganda. The 1957 Disney TV episode Our Friend the Atom is a perfect example of this. What are the dangers of resorting to such forms of explanations in the aftermath of a nuclear disaster? In 2015 and 2017, I spent a total of 14 months in Japan examining the public’s interactive experience at state-sponsored centers and public activities that explain radiation. I found that while the information on radiation is easy to understand, many aspects of its hazards are carefully concealed. In particular, the government’s educational approach shifts the post-Fukushima Japanese public’s attention away from manmade danger and toward a vision of naturalness, technological amusement, and scientific amazement. In doing so, this approach downplays the risk inherent to residual radioactivity in Fukushima.
 
The naturalness of radiation. One way to neutralize the perceived harmfulness of radiation is to make the phenomenon appear as natural as possible, by emphasizing the radioactivity coming from natural sources. At the Centre for Environmental Creation, one of the most popular attractions is an enormous spherical theater, where visitors are bombarded with sounds and images in a 360-degree multisensory experience that describes radiation as a natural part of daily life. “It can be found everywhere! From the sun’s ray to the mineral in the earth,” claims the theater’s narrator. “Without radiation, no life would exist on Earth!” After these explanations, an enormous Boeing passes above theatergoers’ heads in the cinematic sky, and the amount of radiation exposure received during an intercontinental flight is said to be higher than the level of radiation found in Fukushima. Their necks strained upward, visitors mumble words of apparent relief.
 
What the theater fails to explain, however, is that there is nothing natural about the radioactive isotopes released during the Fukushima nuclear disaster, and that background radiation has little to do with the hazards of breathing or swallowing fission products—which are not rays, but dust-like particles. For instance, strontium 90, if inhaled or ingested, mimics calcium to enter an individual’s bone marrow and cause lifelong radiation exposure. This exposure can cause mutations in living cells—a permanent alteration that can lead to cancers, genetic problems, or immune disorders.
 
It’s all fun and games. Information about radiation is often promoted through an enjoyable experience that conceals disturbing aspects of the phenomenon. In front of a giant interactive screen, for example, children can move their bodies to “block” radiation. By selecting the proper material, they can block either radioactive alpha particles, beta particles, or gamma rays. They pretend that their bodies are thick metal plates used to hamper harmful external exposure. By doing so, they collect points, and at the end of the game, the child with the highest score wins.
 
Figure-1.jpg
In an interactive game at the Fukushima Prefectural Centre for Environmental Creation, participants use their body movements to “block” radioactive rays or particles
 
By transforming radiation protection into a game that focuses on blocking external radiation, children do not learn of the risk of internal contamination from radioactive particles such as cesium 137, which was released in significant amounts by the Fukushima disaster. If internalized, cesium 137 gets distributed throughout the body, irradiating soft tissues such as muscles and ovaries. And because the children’s game blocks radiation in “real time,” there is no mention of any delayed health effects of radiation exposure, such as potential harmful genetic changes.
 
At the Decontamination Info Plaza, the government promotes similar activities. Situated in the city of Fukushima, the Plaza was established in January 2012 as a joint program between the prefecture of Fukushima and Japan’s Ministry of the Environment. The Plaza’s purpose is to provide information about radiation in general, as well as explanations about monitoring methods, workshops on decontamination, and advice on contaminated sites. Basic information about radiation is presented to the public in a very accessible, visual, and interactive form.
 
For example, an interactive model helps younger visitors understand the process of decontamination. The model consists of a miniature house in a transparent plastic box filled with small white and red balls. The white balls represent uncontaminated soil; the red balls stand for radioactive pollutants and are found on the house rooftop and in the soil. With a toy shovel, visitors can pick up the red balls and dispose of them in a plastic container, isolating them from the rest of the environment. By playing with the toy shovels and trying to “successfully” get rid of the radioactive pollutants, decontamination acquires a tangibility that feels like a safe game. Children do not have to put on protective suits before separating the balls, and there is no recognition that the decontamination process presents health hazards from radiation, either from external or internal exposure.
 
Radiation is our friend! A third way to downplay the perception of radiation danger is to link radiation with the wonders of science and technology. This was particularly apparent during an April 2016 open house organized by the National Institute of Radiological Sciences, Japan’s leading radiological institute, which is situated in Chiba, east of Tokyo. Titled “I Want to Know More! What Can You Do with Radiation?” the public fair was a popular event at which visitors could see the institute’s research facilities, the latest PET scan technology for medical imaging, and the cyclotrons used in nuclear medicine to produce radioisotopes. A special elevator led down to the Heavy Ion Medical Accelerator, situated in an impressive subterranean facility.
 
As I walked through the underground maze of this metallic behemoth, it became apparent that families were overcome by the scale of the apparatus. Indeed, as one parent said to his child, “It looks like a spaceship, right?” At this institute, manmade radiation was effectively linked to technologies that sustain life. For instance, the open house showed how the radiation-related devices at the institute produce particle therapies to treat cancer.
 
While there was nothing inaccurate about the center’s explanations of radiation as a medical treatment, the information presented was unrelated to the dangers faced during a nuclear disaster. If visitors wanted to hear more about such risks, they had to visit the station called “Impact of Fukushima.” The small station was, however, much less appealing than the other venues. It consisted of four small posters that focused on the decontamination process without explaining the adverse health effects of exposure to manmade radioisotopes. Children were much more interested in learning about the giant particle accelerators. Radiation was emphasized as a useful agent that could penetrate the body and kill harmful tumors, as was demonstrated on medical dummies during the event. In the end, by heavily framing radiation information around a beacon of technological wonder, the public opening day glossed over the danger of radioactive contamination and selectively amplified the beneficial aspects of radiation.
 
Education vs. propaganda. In interviews that I conducted with officials and technical advisors employed at the aforementioned places, I was told that Fukushima is afflicted by “harmful rumors” surrounding the real extent of radiation harm and that this misunderstanding stems from public ignorance of radiological science. It is in this context that government-sanctioned approaches aim to provide “basic information” that will help citizens fear radiation in an “appropriate way,” thereby creating an environment in which people feel they can safely return to Fukushima. While this is a worthy endeavor, the government’s approach emphasizes specific understandings of radioactivity that overshadow the particular risks introduced by manmade radioactive pollutants resulting from a nuclear accident.
 
Ultimately, I have doubts about these education programs. They are selective in their nature, making only certain aspects of radiation tangible through their public activities, while rarely explaining in detail the dangers of adverse health effects linked with residual radioactivity. From my viewpoint, their purpose seems to be dual: While they aim to shed light on the phenomenon of radiation, they are also covertly looking to defuse the threat of widespread societal unrest, to reclaim political control and economic stability, and to pacify a fearful public—and in ways that are perhaps more beneficial to the state than to affected individuals.
 
In a community where dangerous residual radioactivity has become a public everyday concern, coming to grips with serious contamination requires more education than ever before. The important word here is education. Not state propaganda disguised as education. There is a fine line between these two, but it is a line that needs to be clearly drawn. While Japanese state approaches are innovative in their interactivity and freedom from jargon, they are less so in their content.
 
I strongly agree that the existence of state-sponsored educational programs is better than to simply ignore radioactive risk. But mobilizing specific explanations that downplay the real risk faced by citizens is not sustainable. Doing so will reproduce the ignorance, secrecy, and values that led to this disaster. Public well-being, democracy, and science cannot thrive in such context. An unbiased effort to educate people about the specific hazards of radioactive contamination, and correct misunderstandings about the risk of radiation exposure, does not have to be delivered in a dry and clinical manner. It can be as fun and engaging as anything the Japanese centers, exhibits, and public days are already doing.
 
There is one scene from my time in Japan that I cannot forget: the unadulterated smile of the happy child who had won the contest of blocking radiation. While the kid had learned much about radiation, he had learned little about the complexity of radiation hazards. I could not help thinking of Major Kong straddling the bomb in the film Dr. Strangelove, enjoying the nuclear ride without thinking about it too much, shouting “Yee Haw!” at the top of his lungs.

Fukushima wild boar leather baby shoes?

image.php.jpg
Date goes whole hog into boar leather business in Fukushima
[Translated by the Japan Times]Wild boar leather is said to breathe well and resist chafing. It is used in Date, Fukushima Prefecture, to make products like babies’ first walking shoes because it is soft and fits well.
 
The wild boar are captured by local hunters, and their skin goes through radiation testing before and after tanning to confirm safety.
 
The corporation initially wanted to sell the meat, but they had to give up on the idea because eating wild boar caught in the area was banned after the 2011 core meltdowns at the Fukushima No. 1 power plant.
 
They came up with the idea of developing leather products after learning about a company in Tokyo’s Sumida Ward that tans wild animal hides. After repeated talks with representatives from the local tourism industry, the corporation began selling leather products in April 2015. It currently employs seven staffers and 16 artisans for the project.
 
As the government continues to ban shipments of wild animal meat from the region due to radiation concerns, the boar population is growing and causing serious crop damage. Over 1,800 of them have been captured in the city in the six years since the meltdowns.

Eight years after Fukushima nuclear meltdown, workers still facing radiation risk

safe_image.php.jpg
Workers at the Fukushima plant still don’t know how long they have to stay behind cleaning up the mess from the 2011 nuclear meltdown.
February 22, 2019
TEPCO officials recently said to Akahata that high-risk zones in the Fukushima Daiichi plant have become smaller and that now workers do not need to wear a full-face mask and a protective suit in 96 percent of the plant premises. This is because the level of radioactive materials in the air has decreased as a larger area of the site is now covered with concrete, according to officials. At the crippled nuclear power plant, the number of workers coping with the aftermath of the 2011 nuclear accident, though, is still more than 4,000 per day.
However, the hidden reality regarding contamination risks seems to differ from the impression the utility wanted to create by citing the figure “96 percent.” In a recently published survey of Fukushima workers conducted by TEPCO, of the respondents who are anxious about their exposure to radiation, nearly half feared that their health would be damaged in the future. In another question in the same survey, more than 40 percent were concerned about working at the nuclear power plant.
The most common reason for their concern was that they have no idea how long they need to work at the plant because it is unclear how much work remains to be done. They are also worried about the risk of radiation-induced health damage in the future with no guarantee of a stable income. Without a worker-friendly environment, the decommissioning of the crippled reactors will be extremely time-consuming.
The storage of radiation-contaminated water is another major issue. Around 100-150 tons of polluted water is produced every day at the plant, which means that a 1,000-ton tank is filled up in seven to ten days. Currently, around 1.1 million tons of radioactive water are stored on the plant premises, but under TEPCO’s plan, the maximum planned storage capacity is only 1.37 million tons.

‘We were driven out’: Fukushima’s radioactive legacy

MBBHR4RGHMI6TNNUDUMN7N5QQQ.jpg
In March 2017, the government lifted its evacuation order for the center of Namie.
“This is the worst time, the most painful period.” For the people of Namie and other towns near the Fukushima plant, the pain is sharpened by the way the Japanese government is trying to move beyond the tragedy, to use the 2020 Tokyo Olympics as a symbol of hope and recovery, a sign that life can return to normal after a disaster of this magnitude.
If we give up, we would lose our town, and as mayor, I will work with all my heart to prevent that.” But many residents say the central government is being heavy-handed in its attempts to persuade people to return, failing to support residents’ efforts to build new communities in places like Nihonmatsu, and then ending compensation payments within a year of evacuation orders being lifted.
In other towns around the nuclear plant, people have complained that arbitrarily decided compensation payouts — more for people deemed to have been in radiation-affected zones, far less for tsunami victims, nothing for people just a mile outside the zone most affected — have divided communities and caused resentment and friction.
“This is a place desperate to attract people to return, but this reduces our attractiveness for young people,” said Riken Komatsu in the fishing port of Onahama, who is working to rebuild a sense of community and raise awareness about problems with the reconstruction effort.
The biggest tragedy now is the high rate of suicides.” Kazuhiro Yoshida, the embattled mayor of Namie, said fears about radiation are not the only reason people aren’t returning; many complain the deserted town lacks amenities.
“The scale of the problem is clearly not something the government wants to communicate to the Japanese people, and that’s driving the whole issue of the return of evacuees,” said Shaun Burnie, senior nuclear specialist with Greenpeace.
It says radiation levels in parts of Namie where evacuation orders have been lifted will remain well above international maximum safety recommendations for many decades, raising the risks of leukemia and other cancers to “unjustifiable levels,” especially for children.
In the rural areas around the town, radiation levels are much higher and could remain unsafe for people beyond the end of this century, Greenpeace concluded in a 2018 report. Greenpeace has been taking thousands of radiation readings for years in the towns around the Fukushima nuclear plant.
“The idea that an industrial accident closes off an area of Japan, with its limited habitable land, for generations and longer — that would just remind the public why they are right to be opposed to nuclear power.”
Four-fifths of Namie’s geographical area is mountain and forest, impossible to decontaminate, still deemed unsafe to return.
When it rains, the radioactive cesium in the mountains flows into rivers and underground water sources close to the town.
Komatsu says reconstruction has been imposed from above, a problem he says reflects, in a broader sense, what Japan is like.
Today, Namie’s former residents are scattered across all but one of Japan’s 47 prefectures.
“For the past eight years, we have seen the destruction of the area, the destruction of the community, and it will be difficult to bring people back,” he said.
With young people moving away, the elderly, who already feel the loss of Namie most acutely, find themselves even more alone.
Now, the damage is more severe because young people are not returning. The elderly who come back feel pessimism and depression.
Six Olympic softball games and a baseball game will be staged in Fukushima, the prefecture’s bustling and radiation-free capital city, and the Olympic torch relay will start from here.

The State of Nuclear Emergency Declared after the Fukushima Meltdown is Still On Today!!!

medical situation
1. Radioactive contaminated water still keeps accumulating:
2. High-level radiation from Fukushima plant is still being emitted daily.
3. Unfairness of forcing Fukushima residents to live with radiation up to 20 mSv/year.
4.Termination of housing allowance for “voluntary” evacuees from Fukushima, a serious violation of human rights.
5. The number of children with thyroid cancer is increasing although the government refuses to recognize the accident as its cause.
6.Recommendations from the UN Human Rights Council to the Japanese government (UNHRC, Oct. 2018)
The government is obliged:
6.1. to prevent and minimize, as much as possible, children from being exposed to radiation;
6.2. to change back from “20 mSv” to “1 mSv” per year standard before retracting evacuation orders, especially for children and women of childbearing age;
6.3. to not pressurize families to return to Fukushima by terminating housing allowance. (United Nations Human Rights Council, October 2018)

Who will be there?

By Kitty commenting on Abe makes sales pitch for Fukushima sake at Davos:
Prime Minister Shinzo Abe and other Japanese officials toast with sake produced in Fukushima Prefecture during the Japan Night …
The real killers, the strong beta and gamma-emitting, high level radionuclides like 90Sr, 137Cs, 99Tc and 129I , cobalt 60, Iridium are present in the soil in concentrations, hundreds of times higher than what they are saying in Japan. That is easy to see by the Geiger counter readings. Fukushima radionuclides can be in found very high concentrations across Japan from Fukushima to Yokohama, based on Busby and kaltofen sampling and analysis..
It is not simply cesium 137 that exists there.
An absorbed bolus of  80 billionths of a gram of any one of these beta-gamma  radionuclides, causes acute systemic poisoning and radiation poisoning. The results can be either acute death or prolonged agony and death. There will be death, If there is a massive bolus ingested. These are the most poisonous and dangerous substances on earth.
If  1 ounce of any of these radionuclides- substance : st90, 137Cs, 99Tc and 129I , cobalt 60, were dumped on a group of people it would be like the cesium 137 exposure in Brazil or worse.
If  any one of these radionuclides :90Sr, 137Cs, 99Tc and 129I Iridium, cobalt 60 was diluted in an inert powder for example, that  diffused the RADIONUCLIDE onto 10,000 people, gathered for a festival or event , 3 quarters of them would die horrible deaths in 2 weeks and the rest would have tumors and organ damage that would kill them in a few months.
Obviously the sailors on board the Ronald Reagan did not get such a dose but it came close for some of them.
Radioactivity decreases, with the square of distance. Chronic ionized radiation-wave exposure is dangerous  but , those the high level of those and other RADIONUCLIDEs present do not bode well for Japan in the concentrations that exist from Fukushima to tokyo that have been recorded by Busby and kaltofen.
Nucleoapes like to keep the eyes off the lethal radionuclides that are actually emitting the radiation.
There are also the highly potent alpha emitting, uranic and Transuranic alpha emitters like u235, u238, plutonium, AMERICIUM and actinides like Californium that are destroying the human genome in Japan. The beta-gamma emitters do too, but are not as effective and  as potent, as mutagens and acute carcinogens because of their solubility and other chemical properties.
The Uranics, transuranics, actinides, are causing lung cancers, pancreatic cancers and sharp increases in birth defects from mutagenesis,  and teratogenesis across Japan now.
A great deal of Japan’s water supply is probably  heavily contaminated with tritium by now.  TRITIUM is a strong teratogen, that is known to substantially increase incidence of leukemia. Tritium actually covalently bonds to DNA, protein, fat tissue  and muscle tissue, unlike other radionuclides tritium acts exactly like hydrogen does in the body and the body is constantly doing chemical conversions of proteins using hydrogen and tritium ions in metabolic, acid-base, and enzyme reactions in the body.
The nucleoapes have gone out of their way, to obscure the deadly, insidious-effects of tritium on the human genome, chromosomes and the human body.
We are bags of mostly saline water solutions,  proteins, fat, with some bone in us. When we ingest radionuclides they are sometimes  diluted enough by our water and protoplasm, to not cause recognizable or apparent damage and acute symptoms. It is so with the highly water soluble saline analogs like cesium and strontium.
Dr Chris Busby:
Einstein, politics, physicists-nuclear physicists, and reality

The Uranics, transuranics, actinides are not so soluble because they are heavy metals. Particles of these radionuclides, that  get stuck in the lungs and gi tract are particularly deadly. Many of these radionuclides can be biotransformed or chemically transformed into sulfates and organometallics that are easily absorbed into the body.
Then there are the evil-monkeys that says that some radionuclides increase our resistance to RADIONUCLIDE exposure and bioccummulation. Don’t ya know radioactive tritium increase incidence of leukemia, as has been shown in rigorous studies and case studies, its hormetic!
Question. What are the Four most poisonous substances known to humans that are not radionuclides?
Answers
1. Sarin gas is an organophosphate chemical weapon.
20 micrograms will kill you
2. Botulin toxin: Used cosmetically as a neuromuscular block agent, to get rid of wrinkles is lethally toxic in a bolus of 150 micrograms.
Botulin toxin is used to relax muscles and give the illusion that wrinkes are gone cosmetically. Botulin is used because of its extreme potency and length of duration,of action.
Botulin toxin has to be highly diluted and administered by and expert, for any purpose in the human body.
Botulin toxin is lethaly toxic in millionths of a gram concentrations. You can barely see a millionth of a gram with a powerful microscope.
Drugs are dosed at thousands of a gram,that is milligrams. A milligram is a barely detectable spec on a piece of paper to the human eye.
3. 220 micrograms of Ricin toxin from castor beans can kill a child
4. 300 micrograms of fentanyl can kill an adult. Fentanyl analogs are even more potent.
The Moscow theater hostage crisis (also known as the 2002 Nord-Ost siege) was the seizure of a crowded Dubrovka Theater by 40 to 50 armed Chechens on 23 October 2002 that involved 850 hostages and ended with the death of at least 170 people.
It is known that the Russians used a fentanyl-like agent to try to sedate the Chechens, who were holding the hostages in the theater. Unfortunately fentanyl is very hard to dose and disperse as an aerosol. A highly toxic agent like Fentanyl, has to be prepared in such a very special way, so that only its sedative effects are manifested.
Many of the innocent hostages in Nord-Ost, siege died from fentanyl poisoning from the compounded-fentanyl gas, used by the Russians to try to sedate the chechens, before they stormed the theater.
On the flip side of the coin, Sarin, when aerosolized with a suspending agent that works and diffuses the poison in high enough concentrations, is a deadly nerve gas that will kill thousands, in a few square miles with only a few, weaponized Cannisters, detonated.
The Tokyo subway sarin attack-Subway Sarin Incident was an act of domestic terrorism perpetrated on 20 March 1995, in Tokyo, Japan, by members of the cult movement Aum Shinrikyo. In five coordinated attacks, the perpetrators released sarin on three lines of the Tokyo Metro (then part of the Tokyo subway) during rush hour, killing 12 people, severely injuring 50 (some of whom later died), and causing temporary vision problems for nearly 1,000 others. The attack was directed against trains passing through Kasumigaseki and Nagatachō, where the Diet (Japanese parliament) is headquartered in Tokyo
The Aum sarin attack in the Tokyo subways only killed 12 people. They used relatively large amounts of sarin in closed, relatively small areas, with sealed spaces.
They absolutely did not know what they were doing, otherwise they would have known that high doses of sarin have to be aerosolized in a suspending agent like a gas that is liquid under pressure, to properly disperse enough of the agent for it to be widely, dispersed and effectively lethal to a large group of people.
Many radionuclides, and especially the corrosive salt beta-gamma emittors and halogens like I131 and I129 are lethal in billionths of a gram . It even says so in toxicology profiles because, some of these radionuclides are used as radiopharmaceutical agents to treat cancer.
Bllionths of a gram, of any substance, is not even visible with a high powered microscope.
Radionucides are ionizing radiation emitters, as well as being the most poisonous substances to living things on earth, in the universe.
Billionths of a gram concentrations of these elements are highly detectable in billionth of a gram concentrations with scintillometers, gamma spectrometers, and decent pancake Geiger counters.
One of the main difficulties with proving how acutely lethal or chronically damaging RADIONUCLIDE are after nuclear accidents, or with chronic exposure to nuclear waste, are the chaotic mechanisms of dispersion of the radionuclides after catastrophes or in-situ.
Think of the Russian, poisoned with polonium, in London. He was dosed with a nanogram amount of polonium that caused him to die a slow painful death,from systemic organ failure for which there was no cure. He died days after the poisoning.
Boluses of cesium 137, and iodine 131 can kill quite quickly or at lower doses, can kill like the polonium did the murdered Russian in prolonged agony.
Who will be there, to prove what caused people dying a days, weeks or a month, after a.large exposure. Who will speakup for causative agents, after years of bioaccumuted exposure, when no one is even properly looking for the causative agent-RADIONUCLIDE or radionuclides?

Radiation doses underestimated in study of city in Fukushima

understimated radiation Date jan 9 2019.jpg
Workers decontaminate land in Date, Fukushima Prefecture, in 2013.
 
January 9, 2019
A nuclear physicist who has drawn attention for tweeting about fallout from the Fukushima nuclear disaster has admitted that he and a colleague underestimated radiation doses in an article for an international scientific journal.
Ryugo Hayano, professor emeritus at the University of Tokyo, said the error, which he recognized on Jan. 8, was “unintentional.”
The article, carried in the Journal of Radiological Protection’s online edition in July 2017, listed average radiation doses that were one-third of the actual levels for people in Date, a city around 60 kilometers northwest of the crippled Fukushima No. 1 nuclear plant, he said.
Hayano’s admission came after an atomic nucleus expert contacted the journal last year to point out unnatural data carried in the report and call for a correction.
The radiation doses in the article were based on figures kept by Date residents after the nuclear accident unfolded in March 2011.
“Even if residents lived in the most contaminated area of Date for 70 years, the median of the doses would not exceed 18 millisieverts,” the article concluded.
However, Shinichi Kurokawa, professor emeritus with the High Energy Accelerator Research Organization, an institute jointly used by national universities, raised doubts about the data presented in some sections of the report.
When Hayano and his colleague re-examined the figures, they found that they mistook a monthly dose recorded on a dosimeter as the figure for three months of exposure.
Hayano said the conclusion of the report still stands.
“Even after the error was fixed, I believe the average of annual doses will be within the 1-millisievert mark,” he said.
The benchmark upper limit for radiation exposure among ordinary people is 1 millisievert a year.
Hayano has frequently tweeted about radiation levels and doses from the nuclear disaster.
He was also involved in another research paper that analyzed radiation doses among people in Date. Kurokawa also questioned the veracity of a chart in the second report.
The second report has often been cited in discussions by the government’s Radiation Council on setting standards for protecting people from radiation.
The two research papers were produced after the Date city government provided Hayano’s research team with data on radiation doses of about 59,000 residents.
But it has emerged that data for 27,000 citizens were provided without their consent.
The city plans to set up an investigation panel to find out why it occurred.
Date has a population of 61,000.

Town that hosts disaster-hit Fukushima nuclear plant aims to allow daytime access to special zone in 2020

n-fukushima-a-20181214-870x601.jpg
Futaba in Fukushima Prefecture, where restrictions may be lifted to allow daytime access in 2020, is seen in November
December 13, 2018
FUKUSHIMA – One of the municipalities that hosts the crisis-hit Fukushima No. 1 nuclear plant is considering lifting restrictions on daytime access in spring 2020 to an area being rebuilt in the town center, sources close to the matter said Thursday.
The town of Futaba, Fukushima Prefecture, where units Nos. 5 and 6 of the complex are located, became a ghost town after the 2011 disaster due to high levels of radiation. Those wishing to visit need to apply in advance for permission to enter and must pass through a checkpoint.
But such restrictions would be lifted during the daytime for access to a special zone several kilometers from the Fukushima plant on the Pacific coast, where government-funded decontamination and reconstruction work is underway, with the aim of evacuees returning in the spring of 2022.
To lift the restrictions, the town will have to meet government criteria to be unveiled by the end of the year. If realized, the move will pave the way for the town to be rebuilt.
After the massive earthquake and tsunami triggered the world’s worst nuclear catastrophe since the 1986 Chernobyl disaster, the whole of Futaba was designated a no-go zone for residents, with radiation levels exceeding 50 millisieverts per year.
The town’s plan to mark the special zone as a reconstruction hub was endorsed by the central government in September last year. The town said at the time that in most of the area radiation levels had fallen below 20 mSv per year, with figures around Futaba Station brought down below 5 mSv per year.
Decontamination work has been conducted to make sure radiation levels will be below 20 mSv per year throughout the special zone by the spring of 2020. The government eventually aims to lower the levels below 1 mSv per year.
The International Commission on Radiological Protection sets radiation exposure under normal situations at 1 mSv per year and says 100 mSv of exposure over a lifetime would increase the possibility of developing cancer by up to 1 percent.
Under emergency situations, the ICRP sets a limit of 20-100 mSv of annual radiation exposure.
In the special zone, which will occupy about 560 hectares, or 10 percent of the town, residential areas and commercial facilities will be built. Futaba envisions some 2,000 residents will eventually live in the area.
With more residents and construction workers expected to come to the area, the town is likely to discuss measures with the central government to beef up surveillance through the use of security cameras or patrols.
Five other municipalities near the Fukushima No. 1 plant aim to build similar reconstruction hubs for the return of their own evacuees.
All six municipalities are planning to have evacuation orders lifted in the hub zones by the spring of 2023 but Futaba is the first to announce plans for free access during daytime.
The Fukushima No. 1 plant spewed a massive amount of radioactive materials after a magnitude 9.0 earthquake triggered tsunami that flooded the facility on March 11, 2011.
Reactor Nos. 1 to 3 suffered fuel meltdowns, while hydrogen explosions damaged the buildings housing units Nos. 1, 3 and 4. Reactor Nos. 5 and 6 achieved a cold shutdown after several days.
The disaster left more than 18,000 people dead or missing. As of November, more than 54,000 people were still unable to return to their homes.

Fukushima sake shop opens in New York

Plainly criminal. Taking advantage of the unknowing American public and at the same time using such sales as propaganda in Japan telling to the Japanese public that it is safe, look even the Americans buy it. 
gjkkjl.jpg
December 2, 2018
The Fukushima government has opened a sake shop in New York specializing in brews from the prefecture.
 
The shop opened its doors on Saturday inside a commercial facility in Manhattan. Officials from the prefecture and the facility celebrated the occasion.
 
Sake sales are booming in the United States. Exports to the US have increased 50 percent in the past 10 years.
 
Sakes brewed in Fukushima Prefecture have performed well in competitions. The shop offers 50 brands from 11 breweries.
 
One customer said he’s tasted Japanese sake several times before, but none were as good as the one he tried in the shop. He said he would like to visit Fukushima someday.
 
A Fukushima tourism official said breweries in the prefecture are having a hard time finding buyers since the 2011 disaster. He said he hopes the shop will boost the image of Fukushima’s sakes worldwide.
 
The shop will operate until March next year.

Abe, IOC chief to visit Fukushima venue for 2020 Olympics

10325401_10204102291517461_1178696755673550066_n

November 5, 2018
TOKYO – Prime Minister Shinzo Abe and International Olympic Committee President Thomas Bach plan to visit the venue in Fukushima for the 2020 Tokyo Olympics later this month, a government source said Sunday.
With a “reconstruction Olympics” being one of the fundamental themes of the Summer Games, the government hopes the visit planned for Nov 24 will increase momentum toward the recovery of the country’s northeastern region, devastated by the 2011 earthquake, tsunami and ensuing crisis at the Fukushima Daiichi nuclear power plant.
Bach will visit Japan to attend a two-day general assembly meeting of the Association of National Olympic Committees starting Nov 28, followed by an IOC Executive Board session, both to be held in Tokyo.
The Olympic torch relay will start in Fukushima Prefecture on March 26, 2020, with the flame scheduled to be lit in the ancient Greek city of Olympia on March 12 the same year, a day after the ninth anniversary of the 2011 disaster.
The city of Fukushima will host six softball games including a match played by the Japan team on July 22 as the first event of the Olympic Games.

Temporal changes in 137Cs concentrations in fish, sediments, and seawater off Fukushima Japan

serveimage
Demersal fish live and feed on or near the bottom of seas or lakes (the demersal zone). They occupy the sea floors and lake beds, which usually consist of mud, sand, gravel or rocks. In coastal waters they are found on or near the continental shelf, and in deep waters they are found on or near the continental slope or along the continental rise. They are not generally found in the deepest waters, such as abyssal depths or on the abyssal plain, but they can be found around seamounts and islands. The word demersal comes from the Latin demergere, which means to sink.
 
Demersal fish consist of Benthic fish and benthopelagic fish, they are bottom feeders. They can be contrasted with pelagic fish which live and feed away from the bottom in the open water column. Demersal fish fillets contain little fish oil (one to four percent), whereas pelagic fish can contain up to 30 percent.[not verified in body]
 
Benthic fish, sometimes called groundfish, are denser than water, so they can rest on the sea floor. They either lie-and-wait as ambush predators, maybe covering themselves with sand or otherwise camouflaging themselves, or move actively over the bottom in search for food. Benthic fish which can bury themselves include dragonets, flatfish and stingrays.
 
Benthopelagic fish inhabit the water just above the bottom, feeding on benthos and zooplankton. Most demersal fish are benthopelagic.

 

October 15, 2018
Abstract
We analyzed publicly-available data of Fukushima 137Cs concentrations in coastal fish, in surface and bottom waters, and in surface marine sediments and found that within the first year of the accident pelagic fish lost 137Cs at much faster rates (mean of ~1.3% d-1) than benthic fish (mean of ~0.1% d-1), with benthopelagic fish having intermediate loss rates (mean of ~0.2% d-1). The loss rates of 137Cs in benthic fish were more comparable to the decline of 137Cs concentrations in sediments (0.03% d-1), and the declines in pelagic fish were more comparable to the declines in seawater. Retention patterns of 137Cs in pelagic fish were comparable to that in laboratory studies of fish in which there were no sustained 137Cs sources, whereas the benthopelagic and benthic fish species retained 137Cs to a greater extent, consistent with the idea that there is a sustained additional 137Cs source for these fish. These field data, based on 13,511 data points in which 137Cs was above the detection limit, are consistent with conclusions from laboratory experiments that demonstrate that benthic fish can acquire 137Cs from sediments, primarily through benthic invertebrates that contribute to the diet of these fish.

Japan recognizes first death related to Fukushima cleanup

ghgjhkj.jpg
September 7, 2018
The Japanese government has recognized the first death associated with cleanup work at the Fukushima Daiichi nuclear power plant after the tsunami disaster in March 2011, according to the Ministry of Health, Labour and Welfare.
The government designated the death of an unnamed man in his 50s as an “industrial accident.” The man, who had worked at the plant from 1980 to 2015, was diagnosed with lung cancer in February 2016.
After the 2011 tsunami that was triggered by a 9.0-magnitude earthquake, the man was assigned to “radiation control” work in which he was responsible for monitoring radiation levels and work time of cleanup crews.
The Ministry of Health, Labour and Welfare recognized his cancer and death as related to his work at the plant. A committee of experts determined his accumulated radiation level exceeded government standards.
Kunihiko Konagamitsu of the ministry said 17 workers had applied to be considered cases with an “industrial accident” designation, including three with leukemia and one with thyroid cancer. Two workers withdrew their requests, five were dismissed, and five are still under review.
The March 11, 2011, quake was the worst to hit Japan and lasted nearly six minutes. More than 20,000 people died or went missing in the earthquake and tsunami that followed.
Three reactors at the Fukushima Daiichi nuclear plant, operated by Tokyo Electric Power Co. or TEPCO, melted down in the nation’s worst nuclear disaster. The damaged reactors released radioactive materials into the air and more than 100,000 people were evacuated from the area. Forty-five thousand workers were involved in the ensuing cleanup.
In 2015 Japan health officials confirmed the first case of cancer linked to cleanup work at the plant.
In 2016, TEPCO said that decommissioning the reactor was like climbing a mountain and that it could take as long as 40 years.

Fukushima unrecognized threat of radioactive microparticles

hghkmlmùù

Fukushima Microparticles, An Unrecognized Threat

In the years since the initial disaster there have been disparities between the official radiation exposure estimates and the subsequent health problems in Japan. In some cases the estimates were based on faulty or limited early data. Where a better understanding of the exposure levels is known there still remained an anomaly in some of the health problems vs. the exposure dose. Rapid onset cancers also caused concern. The missing piece of the puzzle may be insoluble microparticles from the damaged reactors.
 
What are microparticles ?
These microscopic bits of fuel and other materials from the reactor meltdowns have been found around Japan since soon after the disaster. Citizens with hand held radiation meters first discovered them as highly radioactive fine black sands on roadsides and gutters. These substances eventually caught the attention of researchers who determined they are tiny fused particles of vaporized reactor fuel, meltdown byproducts, structural components of the reactors and sometimes concrete from the reactor containments. The Fukushima microparticles are similar to “fuel fleas” or “hot particles“. Hot particles or fuel fleas have been found at operating nuclear reactors that had damaged fuel assemblies. These fused particles found around Japan are different in that they are a byproduct of the reactor meltdowns.
The small size of these microparticles, smaller than 114 μm makes them an inhalation risk. Other studies have also confirmed the size is small enough to inhale. These microparticles have been found near Fukushima Daiichi, in the evacuation zone, outside of the evacuation zone and as far away as Tokyo.
 
How microparticles were created at Fukushima Daiichi
The heat of the meltdown processes reached temperatures high enough to cause the nuclear fuel and other materials to break down into small particles. The uranium in the fuel further oxidized and then volatilized once temperatures reached 1900K. As these materials broke down into nanoparticle sized components of the fuel melt process, this set up the conditions for them to condense.  As these materials cooled the fused microparticles were created. Newer studies call these microparticles “CsMPs” (Cesium bearing micro particles).  A 2018 study of how these microparticles were created gives a plain language explanation of the process. https://pubs.acs.org/doi/pdf/10.1021/acs.est.7b06309
“From these data, part of the process that the FDNPP fuels experienced during the meltdown can be summarized as the follows: Cooling waters vaporized, and the steam reacted with Zr and Fe forming their oxides after the loss of power to the cooling system. UO2, which is the main composition of fuels, partially oxidized and volatilized at greater than ∼1900 K. (9,10) The fuel assemblies melted unevenly with relatively less irradiated fuels being heated to a higher temperature as compared with the high burnup fuels and volatilized as evidenced by the 235U/238U isotopic ratio.(9) The fuel assembly collapsed and moved to the bottom of RPV. The temperature increased locally to at least greater than 2400 K based on the liquidus temperature of U−Zr oxides. Locally formed oxides melted to a heterogeneous composition, including a small amount of Fe oxides,(27) which then became a source of Fe−U single crystals and U−Zr-oxide eutectic phases. Specifically, euhedral magnetite nanocrystals encapsulated euhedral uraninite nanocrystals, which would have crystallized slowly at this stage. Liquid U−Zr-oxide nanodroplets were rapidly cooled and solidified to a cubic structure. When the molten fuels hit the concrete pedestal of the PCV, SiO gas was generated at the interfaces between the melted core and concrete and instantly condensed to form CsMPs.(5) The U−Zr-oxide nanoparticles or the magnetite nanocrystals subsequently formed aggregates with CsMPs. Finally, the reactor debris fragments were released to the environment along with CsMPs.”
The microparticles may have left the reactors through multiple processes including containment leaks,  containment venting operations, hydrogen explosions and the later reduction and addition of water in an attempt to control the molten fuel.
 
New study looks at how to quantify these substances
A new study found a useful way to quantify how much of the contamination in an area is due to microparticles (hot particles). By using autoradiography they were able to confirm the number of microparticles in a sample. Soil samples near Fukushima Daiichi ranged from 48–318 microparticles per gram.  The microparticles had high concentrations of radioactive cesiums, in the range of ∼1011 Bq/g. The study stresses the health concern that these microparticles pose due to cellular damage from the highly concentrated radiation level. The authors also mention the risk re-suspension of microparticles in the air poses to the public.
Not just cesiums
A separate study found strontium-90 in the Fukushima microparticles at a ratio similar to what has been found in contaminated soil samples. This study included the amount of hot particles (aka: microparticles) found in soil samples taken in the fallout zone in Fukushima north-west of the plant. They ranged from 0-18 microparticles per square meter of soil. This information confirms that strontium-90 is part of some of these fused microparticles. https://academic.oup.com/jrr/advance-article/doi/10.1093/jrr/rry063/5074550
An ongoing research project and paper by Marco Kaltofen documents these hot particles further. In the 2017 paper they found more than 300 such hot particles from Fukushima Daiichi in Japanese samples.  A hot particle was found in a vacuum cleaner bag from Nagoya, over 300 km from the disaster site. https://www.sciencedirect.com/science/article/pii/S0048969717317953?via%3Dihub
“300 individual radioactively-hot particles were identified in samples from Japan; composed of 1% or more of the elements cesium, americium, radium, polonium, thorium, tellurium, or strontium. Some particles reached specific activities in the MBq μg− 1 level and higher.”
The study found americium 241 in two house dust samples from Tokyo and in one from Sendai, 100 km north of the disaster site.  The sample set collected in 2016 showed a similar instance of highly radioactive hot particles compared to the 2011 samples. This appears to show that the threat from these reactor ejected hot particles has not gone away. A majority of the collected samples were from locations declared decontaminated by the national government.
The above graph is from the 2017 Kaltofen paper. These represent the highest readings for cesium found in their microparticle samples. The highest in the graph is Namie black sand. These black sand substances found around Fukushima prefecture and as far south as Tokyo were discovered to be largely made up of ejected reactor materials based on multiple studies.
The 2018 study we cited earlier in this report to explain the microparticle creation process also confirms some of these microparticles also contain radioactive isotopes of uranium. This further confirms the creation of some of these microparticles from the fuel itself. Uranium poses a particular concern due to the extremely long half lives involved.
 
How these act differently in the environment
In the case of the microparticles that contained Strontium 90, the isotope would normally move with water in the environment. Due to the insolubility of the microparticles, the strontium 90 stays in the top soils. Studies on microparticles predominantly carrying radioactive cesiums showed that the radioactive substances did not migrate through the environment as expected.
Microparticles were found in road gutters, sediment that collected in parking lots, below downspouts and similar places where sediments could concentrate. These initial discoveries hint at how the microparticles could migrate through the environment. The findings of the 2017 Kaltofen study indicate that microparticles can persist years later, even in places that were decontaminated. This may be due to the natural processes that have caused many areas to recontaminate after being cleaned up. There has been no effort to clean up forest areas in Japan. Doing so was found to be extremely difficult. The forest runoff may be one method of recontamination.
 
The risk to humans and animals
The subject of hot particles and the risk that they might pose to human or animal health has been controversial in recent years. Some studies found increased risks, others claimed a lesser risk from these substances. One study we reviewed may have discovered the nuances of when these substances are more damaging.
Most studies on hot particles aimed to determine if they were more damaging than that of a uniform radiation exposure to the same body part. A 1988 study by Hoffman et. al. found that hot particle damage varied by the radiation level of the particle, distance to nearby cells and the movement of the particle within the tissue. A high radiation particle might kill all the nearby cells but cause transformation in cells further away. Those dead cells near the hot particle would stimulate the transformed cells to reproduce faster to replace the dead cells. https://academic.oup.com/rpd/article-abstract/22/3/149/161256
A hot particle of moderate radiation would cause more transformations than cell death of nearby cells. High radiation hot particles that moved around in the organ, in this case the lung, would cause the most transformations. These acted like multiple moderate radiation hot particles transforming cells as they moved around. Those transformations are what can turn into cancers. This study’s findings appear to explain the results found in other studies where fewer cancers were found than they expected in certain groups.
A veteran who was exposed during US atomic testing had experience over 300 basal cell carcinomas. The study concluded that the skin cancers in atomic veterans could be induced by their radiation exposure. Continued exposure to ultraviolet radiation then promoted those cancers.
Other studies found damage in animal models. A study of hot particles on pig skin showed roughly half of the exposures caused small skin lesions. Two in the higher exposure group caused infections, one of these resulted in a systemic infection. https://inis.iaea.org/collection/NCLCollectionStore/_Public/28/061/28061202.pdf
A mouse study where hot particles were implanted into the skin found increased cancers of the skin. https://www.tandfonline.com/doi/abs/10.1080/09553009314550501
Workers at Fukushima Daiichi in the group with some of the highest radiation exposures were discovered to have these insoluble microparticles lodged in their lungs. When the workers radiation levels didn’t decrease as expected, further tests were done. Scans found the bulk of the worker’s body contamination was in their lungs. The lung contamination persisted on subsequent scans. The looming concern is that these microparticles in the lungs can not be ejected by the body.
 
Risks have been known for decades 
The US NRC issued an information notice related to a series of hot particle exposures at nuclear plants where workers were exposed beyond legal limits. https://www.nrc.gov/reading-rm/doc-collections/gen-comm/info-notices/1987/in87039.html
Damaged fuel was the source in all cases. Even improperly laundered protective clothing was found to be a risk factor. Contaminated clothing from one facility could make it through the laundry process with a hot particle undetected on bulk scans of finished laundry. This would then result in an exposure to a different worker at a different plant who donned the contaminated gear. The hot particles when in contact with skin can give a high dose rate. Plants with even small fuel assembly leaks saw significant increases in worker exposure levels.
“In addition to any increased risk of cancer, large doses to the skin from hot particles also may produce observable effects such as reddening, hardening, peeling, or ulceration of the skin immediately around the particle. “
These problems are thought to only occur in high dose exposures from hot particles. One worker in the review had an estimated 512 rem radiation exposure from a hot particle.  Workers at US nuclear power plants are subjected to strict screening programs when they exit or return to work. This increases the chance of detecting and removing a hot particle before it can do more damage. This also lessens the potential for one to leave the plant site. The general public exposed to a nuclear plant disaster does not receive this level of scrutiny.
 
How this risk may have played out in Fukushima
Soon after the reactor explosions ripped through Fukushima Daiichi, people in the region began complaining of nosebleeds and flu like symptoms. These eventually began being reported as far south as Chiba and Tokyo.  https://www.aljazeera.com/indepth/features/2011/08/201181665921711896.html
The government responded that these complaints were “hysteria” or people trying to scare others. These problems were so widespread and coming from diverse people it had seemed to be a significant sign in the events that unfolded.
On March 21, 2011 there was rain in Tokyo that may have washed out contamination still being ejected at the plant. Events at Daiichi between March 17-21 caused increased radiation releases.
In 2013 there was an unusual uptick in complaints about severe nosebleeds. This happened at the time typhoon Man-yi made landfall in Tokyo. The bulk of the people who responded to a survey by a foreign policy expert working in the office of a member of Japan’s Diet were from the Kanto region (Tokyo) where the typhoon made landfall.
Children in the Fukushima region that were found to have thyroid problems also complained of frequent nosebleeds and skin rashes.  People have described unusual ongoing health problems such as this woman in Minami Soma near Fukushima Daiichi who had odd rashes, a rapid loss of teeth etc.  Cattle housed 14 km from the disaster site have shown with white spots all over their hides, something previously seen after US nuclear tests. https://www.huffingtonpost.com/evaggelos-vallianatos/the-nuclear-meltdown-at-f_b_4209766.html
The USS Reagan was offshore of Fukushima Daiichi March 11 to 14th. Plume maps for iodine 131 (a gaseous release from the meltdowns) blew in the wind north and at times east out to sea during those dates. These same winds could have carried microparticles out to sea. A number of sailors on the Reagan and those working with the rescue helicopters have fallen ill. Eight have died since the disaster. This newer account of the events on the Reagan raise even more concerns about what happened to those trying to save people after the tsunami.
Namie Mayor, Tamotsu Baba resigned his office in June 2018 after a year of off and on hospitalization. He had been undergoing treatment for gastric cancer. He died a few weeks after resigning. His cancer may have predated the disaster, but in the last year his health drastically declined. Namie is in the area of some of the highest fallout from the disaster.
Fukushima plant manager Masao Yoshida died of esophageal cancer in 2013. TEPCO insisted his cancer was not related to the disaster due to the rapid onset. This is a common claim around cancers that could be tied to Fukushima, yet the number of cancers soon after the disaster has been hard to ignore.
As we neared completion of this report the labor ministry announced that the lung cancer death of a Fukushima Daiichi worker was tied to his work during the disaster. The worker was at the plant during the early months of the disaster and worked there until 2015. TEPCO didn’t give specifics of his work role, only mentioning he took radiation levels. TEPCO mentioned that the worker wore a “full face mask respirator” during his work. All of the workers at Daiichi wore the same after ordered to do so after meltdowns were underway. The worker was not among the highest exposure bracket so he may not have been receiving detailed health monitoring. Radiation exposure monitoring during the early months of the disaster was inconsistent and sometimes missed exposures. https://mainichi.jp/english/articles/20180905/p2a/00m/0na/004000c
 
What microparticles change about the disaster
Highly radioactive microparticles were released to the environment during the meltdowns, explosions and subsequent processes in units 1-3 at Fukushima Daiichi.
Microparticles have been found near the disaster site, in the evacuation zone, far outside of the evacuation zone and south into the Tokyo region. These substances persist in the environment and have been found in areas previously decontaminated.
These microparticles significantly change the exposure estimates for the general public. Individual exposures can not be accurately estimated by the use of generic environmental radiation levels as this does not account for the individual’s exposure to microparticles.
Microparticle exposure has multiple variables that create a unique level of risk to the exposed human or animal. They can in the right circumstances cause significant damage to nearby tissues, persist in the body, cause damage, initiate or promote a cancer.
Microparticle exposures may be the missing puzzle piece that explains a number of odd problems tied to the Fukushima disaster. Health problems that showed up soon after the disaster. Exposed populations with aggressive or sudden cancers and other serious health problems that can be created or exacerbated by radiation exposure.
Microparticles continue to pose a public health risk in some parts of Japan that experienced fallout and increased radiation levels due to the disaster.
