November 3, 2019

FUKUSHIMA—A citizens’ group here has released an English radiation-level map for eastern Japan created with input from 4,000 volunteers in response to requests from abroad ahead of the Tokyo Olympics.

“We want people outside Japan to understand the reality of radioactive contamination following the nuclear accident,” said Nahoko Nakamura, a representative of Minna-No Data Site (Everyone’s Data Site), which published the map.

The Fukushima No. 1 nuclear power plant experienced a triple meltdown in March 2011 after a tsunami knocked out its cooling systems during the Great East Japan Earthquake.

Titled “Citizens’ Radiation Data Map of Japan,” the 16-page booklet summarizes the content of the original Japanese map, released in November last year. It also shows projected declines in radiation levels by 2041.

The Japanese version was based on results of land contamination surveys conducted over three years at the request of Everyone’s Data Site.

About 4,000 volunteers took soil samples at 3,400 locations in 17 prefectures in eastern Japan, including Fukushima and Tokyo, and measured radiation levels. The map was compiled with advice from experts.

The group raised 6.23 million yen ($57,500) from 1,288 individuals through a crowdfunding campaign. So far, 15,000 copies have been sold.

Nakamura said the group decided to produce an English version after it received inquiries about the Japanese map from researchers and others overseas in the run-up to the Tokyo Olympics.

Everyone’s Data Site spent about four months creating the English map, working through e-mail and online chats with five volunteer translators overseas, including an American and a Canadian.

The English edition sells for 500 yen, excluding tax. For more information, contact Everyone’s Data Site at (minnanods@gmail.com).

Fukushima is not safe for 2020 Olympics, nuclear scientists warn

Fukushima_I_by_Digital_Globe-630x310.jpg

October 30, 2019

Would Russia hold the 1994 Olympics at Chernobyl, the site of the 1986 meltdown? Only 8-years later, do we really think it’s safe to hold the Olympics on Fukushima soil? What would common sense tell us?

But these are very dark times.

The International Olympic Committee (IOC), the Japanese government, and most news media have ignored the risks one of the worst nuclear disasters in world history: the 2011 Fukushima power plant meltdown.

For years afterward, the Japanese government struggled what to do with millions of gallons of contaminated water and tens of thousands of Japanese refugees. Instead of safer measures, they chose the cheapest solution, spinning the truth in favor of profit and national image over human life.

Scientists warned that almost everything on land is contaminated, and this may include Tokyo which sits 100 kilometers from Fukushima.

Radiation levels may beyond what is safe for humans

According to 60 Minutes Australia, many experts are asking for the Fukushima Olympics to be canceled due to radioactive contamination. Yet, when The Washington Post ran an article on the struggles Fukushima and the residents are facing, there is no mention of what dangers Olympians and spectators may face in an area that has radiation levels way beyond what is safe for humans. Such high levels are likely to continue for decades to come.

In fact, in that same article, Simon Denyer wrote that when it rains, the water itself is radioactive. Residents feel forced by the Japanese government to return, as the government cuts pensions if residents refuse, essentially forcing them and their children for increased risk of cancer and other health problems. Childhood cancer is increasing in the affected zones, Denyer reports.

Why the silence? Where is the IOC? Is it okay for athletes and spectators to spend two weeks in a radioactive zone so that the Japanese government can make everyone forget that radiation exposure is no big deal? Such wouldn’t have to do with money over human life would it? Where is the U.S. news media that often looks for just a big story like this to crack? Why the silence?

As for Japan, what choice does it have but to move forward and accept that almost its entire population is inevitably exposed to radiation.

This is not something they can fix, so the government must reinvent Fukushima as a safe and wonderful place, a place where one can eat the vegetables and fruits from Fukushima, and they can live there healthy and happy. What better way than to repackage horrible facts with a new Fukushima, a safer, healthier one? However, they will have to force their residents to come back in order to seal such a wonderful myth.

Smelling a Nuclear Rat?

Dahr Jamail interviewed Arnie Gunderson that oversaw dozens of nuclear power plant projects in the United States. He faults the Japanese government and the nuclear power plant industry in pushing residents to go back to Fukushima before the 2020 Games. Even more surprising is that the IOC is also, according to Jamail, making very light over the known toxicity of Fukushima where the softball and baseball events will be played. Denyer, however, verified that six total events will take place in Fukushima. Gunderson, with 45 years’ experience with nuclear energy companies says that the goal is profit and that public health is not being considered.

Thyroid cancer, Jamail writes, already is increasing within the 310-mile radius of the disaster, and instances of cancer among children is increasing as well.  In fact, the radiation is not decreasing but increasing at the power plants. Dr. Tadahiro Katsuta of Meiji University in Japan makes the Japanese motive clear: the Japanese government is putting its public image and money over the lives of its citizens. The Japanese government is also putting international athletes and citizens at risk with little regard for their health and safety.

Reporters Dave Zirin and Jules Boykoff went through Fukushima with a radioactive tester. They noted that a reading over 0.23 is seen as unsafe for humans. As they neared the Fukushima Daiichi Unit 1 reactor, the needle read 3.77. The Olympic torch is scheduled to pass near this area.

Who Works in Radioactive Zones without Protection? Athletes and Migrant Workers

They witnessed in Fukushima workers without protective suits putting contaminated soil in black plastic bags and piling them in “pyramids.” While some agencies dispute how dangerous Fukushima is, what is clear is that the Japanese government raised the exposure benchmark for radiation from 1mSV a year to 20 MSV per year, the reporters noted. As an international journalist based in Japan stated, the Japanese government is pushing “propaganda over truth.” The IOC seems happy to play along.

Tens of thousands of Japanese refugees are still displaced and not willing to go back. The question is why wouldn’t people back to their homes, many of which whose families lived there for generations, if it were safe? Why would the IOC be so willing to host the games at a questionable site, even if such posed the slightest risks to athletes?

It does not take a nuclear engineer or scientist to understand that radiation contamination lasts for many years. Why build Olympic venues eight years after that very place had a nuclear disaster? Isn’t such a push egregious, irresponsible, and shameful? Common sense would tell any organizer of any event that such an event should not be placed in areas that could potentially put people at risk.

It’s time to hold the Japanese government and the IOC responsible for their hasty and reckless push to ignore the risks facing displaced citizens, spectators, and athletes and demand that the games be postponed and moved from Fukushima.

These are indeed dark times, where governments and their ties to corporate interests spin truths and make fictions that all of us would like to be real, but sadly money is always at the end of this contaminated rainbow. In the years to come, when the cancer cases mount, these same organizations and governments will pretend they knew nothing. Let’s all remember that.

Warning on Fukushima fallout for Tokyo 2020 Olympians

gjklmm.jpg
International Campaign to Abolish Nuclear Weapons co-founder Tilman Ruff.
October 29, 2019
The Australian Olympic Committee has been urged to inform its athletes and team members about the ongoing health effects of the 2011 Fukushima nuclear ­reactor disaster for those attending the 2020 Tokyo Games.
Tilman Ruff, a public health expert who co-founded the Nobel Peace Prize-winning International Campaign to Abolish Nuclear Weapons (ICAN) in Melbourne, said he had written to the AOC to warn that levels of radioactivity in certain areas could be above the recommended maximum permissible exposure level. He said the Japanese Olympic Committee planned to host baseball and softball competitions and part of the torch relay in Fukushima City, 50km away from the ruins of the Fukushima Dai-ichi nuclear power plant.
In 2011, multiple nuclear meltdowns at the damaged facility caused radioactivity to leak out across Japan and the Pacific.
“It was a catastrophe comparable only to the nuclear meltdown of Chernobyl,” he said. While contamination was not as severe as at Chernobyl, “it was widespread and persists”.
At least 50,000 residents have not yet been able to return to the most affected areas in Fukushima prefecture. “The Japanese government is making a concerted ­effort to present the Fukushima nuclear disaster as over and effectively dealt with in the lead-up to the Olympics. Some of these ­efforts are misleading and should not be accepted at face value,” Dr Ruff said.
He said thyroid cancers had notably increased among young people in Fukushima, with a total of about 200 cases.
He has made several visits to Fukushima since 2011, the latest in May when he provided radiation health advice to the Fukushima prefectural government.
Dr Ruff said he then wrote to the AOC urging it to “properly ­inform and safeguard the best interests of the Australian staff and team, and their accompanying families, especially women who may be pregnant and young children”.
He said short-term visits to areas contaminated by radioactive fallout “now involve low to minimal risk”.
“However, if any (AOC) members or athletes plan to be based in Fukushima or neighbouring contaminated prefectures for weeks or months, they should be informed about the health risks of radiation exposure,” Dr Ruff said.
International physician groups have criticised the Japanese government’s decision shortly after the 2011 disaster to increase the maximum permissible radiation dose for Japanese citizens from one to 20 millisieverts. “Eight years later, it has not reversed that decision,” Dr Ruff said. “No other government in the world has ever accepted such a high level of radiation beyond the immediate emergency phase of a nuclear disaster for its citizens.”
An AOC spokesman said Tokyo 2020 provided regular updates to the IOC regarding the situation. “We have been given assurances that radiation levels in Fukushima City are safe, noting that the IOC Co-ordination Team has made several visits to the region and that ongoing monitoring is conducted independently of the Japanese government,” the spokesman said.

The danger of sourcing food and material from the Fukushima region

Ground-level nuclear disasters leave much more radioactive fallout than Tokyo is willing to admit

August 25, 2019
International concerns are growing over the Japanese government’s plans to provide meals from the Fukushima area to squads participating in the 2020 Tokyo Olympics. The starting point for the Olympic torch relay, and even the baseball stadium, were placed near the site of the Fukushima Nuclear Power Plant. It seems to be following the model of the Tokyo Olympics in 1964, where Japan’s rise from the ashes of the atomic bombs was underscored by having a young man born the day of the Hiroshima bombing act serve as the relay’s last runner. Here we can see the Shinzo Abe administration’s fixation on staging a strained Olympic reenactment of the stirring Hiroshima comeback – only this time from Fukushima.
But in terms of radiation damages, there is a world of difference between Hiroshima and Fukushima. Beyond the initial mass casualties and the aftereffects suffered by the survivors, the atomic bombing of Hiroshima resulted in little additional radiation exposure. Nuclear technology being as crude as it was back then, only around one kilogram of the Hiroshima bomb’s 64kg of highly enriched uranium actually underwent any reaction, resulting in a relatively small generation of nuclear fission material.
Whereas ground-based nuclear testing results in large quantities of radioactive fallout through combining with surface-level soil, the Hiroshima bomb exploded at an altitude of 580m, and the superheated nuclear fission material rose up toward the stratosphere to spread out around the planet, so that the amount of fallout over Japan was minimal.
Even there, most of the nuclides had a short half-life (the amount of time it takes for half the total atoms in radioactive material to decay); manganese-56, which has a half-life of three hours, was the main cause of the additional radiation damages, which were concentrated during the day or so just after the bomb was dropped. The experience of Nagasaki was similar. As a result, both Hiroshima and Nagasaki were able to fully resume as functioning cities by the mid-1950s without additional decontamination efforts.

Fukushima’s radiation increases over time
The Fukushima disaster did not result in mass casualties, but the damages from radiation have only increased over time. The nuclear power plants experiencing core meltdowns had the equivalent of around 12 tons of highly enriched uranium in nuclear fuel – roughly 12,000 times more than the amount of uranium that underwent nuclear fission in the Hiroshima bomb. At one point, the Japanese government announced that Fukushima released 168 times more cesium than the Hiroshima bomb. But even that was merely a difference in emissions; there’s an immeasurable difference between the amount of fallout from Hiroshima, which was left over from a total spread out over the planet at a high altitude, and the amount from Fukushima, which was emitted at ground level.
Hiroshima also experienced little to no exposure to cesium-137 and strontium-90 – nuclides with half-lives of around 30 years that will continue to afflict Japan for decades to come. Due to accessibility issues, most of the forests that make up around 70% of Fukushima’s area have been left unaddressed. According to Japanese scholars, around 430 square kilometers of forest was contaminated with high concentrations of cesium-137. The danger of this forest cesium is that it will be carried toward residential or farm land by wind and rain, or that contaminated flora and fauna will be used in processing and distribution. Indeed, cedar wood from Fukushima remains in distribution in the region, and was even shipped off recently to serve as construction material for the Tokyo Olympics. Meanwhile, the incidence of thyroid cancer in children – a rare condition – has risen all the way from one to two cases before the incident to 217 in its wake. Yet the Abe administration has only impeded a study by physicians, using various government-controlled Fukushima-related investigation committees as vehicles for sophistry and controlling media reporting on the issue.

Abe administration hoping to cut costs in nuclear waste disposal
The economic consequences have been astronomical as well. From an expert group’s analysis, the Japan Center for Economic Research estimated that the 14 million tons of radioactive waste from collecting Fukushima’s cesium-contaminated soil would result in a financial burden of 20 trillion yen (US$187.98 billion) based on the acceptance costs at the Rokkasho-mura radioactive waste disposal center. Contaminated water from the Fukushima Nuclear Power Plant – which already amounts to 1.2 million tons and is expected to increase to 2 million – was predicted to cost fully 51 trillion yen (US$479.35 billion) in tritium and strontium removal costs alone. Factor in the 10 trillion yen (around US$94 billion) in resident compensation, and the amount is close to the Japanese government’s total annual budget. Hoping to cut costs, the Abe administration announced plans to reuse soil waste in civil engineering, while the contaminated water is expected to be dumped into the Pacific after the formalities of a discussion. But few if any Japanese news outlets have been doing any investigative reporting on the issue.
When Abe declared the situation “under control” during the Olympic bidding campaign in 2013, this truthfully amounted to a gag order on the press and civil society. Having the world’s sole experience of filing and winning a World Trade Organization (WTO) case on Fukushima seafood, South Korea may be in the best position to alert the world to the issue of radioactivity and the Tokyo Olympics. I look forward to seeing efforts from the administration.

South Korea express concern about food from Fukushima as Tokyo 2020 Chef de Mission Seminar begins

tepco_2020_olympics.jpg

 

August 20, 2019

The Korean Sport and Olympic Committee (KSOC) has written to Tokyo 2020 organisers to express concern about food from Fukushima being served at the Games.

Organisers confirmed to Reuters that a letter on the issue had been sent on the opening day of the Tokyo 2020 Chef de Mission Seminar.

Fukushima was struck by one of the worst natural disasters ever to hit Japan in 2011, when a devastating earthquake and tsunami caused an accident at a nuclear power plant.

Around 16,000 people lost their lives in the tragedy.

Both Tokyo 2020 and the International Olympic Committee (IOC) have been keen to promote the Games as a tool which could help with the region’s recovery.

Baseball and softball matches will be staged there and Fukushima prefecture will also host the start of the Japanese leg of the Torch Relay.

Produce from Fukushima has been served at official events, including IOC Coordination Commissions, but the KSOC said they are worried about contamination.

Their letter comes at a period of increasing tension between Japan and South Korea.

“Within our planning framework we will respond to them accordingly,” said Toru Kobayash, Tokyo 2020’s director of NOC services, to Reuters.

“We have said that we will respond to them properly. 

“We have had no further questions [from South Korea].”

A trade war has developed between the two countries with South Korea also angry about reported Japanese plans to dump “toxic” water from Fukushima into the Pacific Ocean.

Some voices have even called for a Korean boycott of the Games with the nations further clashing over the appearance of disputed islands on an official Tokyo 2020 Torch Relay map.

The map on the official website includes the Liancourt Rocks, which are governed by South Korea but claimed by Japan.

South Korea calls the islands Dokdo but in Japan they are known as Takeshima, and both countries claim historical ties.

They lie in the Sea of Japan in between the two countries and are valuable due to rich fishing waters and natural gas deposits.

Elsewhere, concerns over sweltering conditions were discussed on day one of the Seminar at the Hotel New Otani.

Rising heat has developed into a major concern before Tokyo 2020 with more than 50 deaths in July as temperatures in Japan approached 40 degrees celsius.

Athletes have also struggled in the weather at the test events, including rowers suffering heatstroke at the World Junior Championships at the Sea Forest Waterway.

The triathlon event was shortened because of the humid conditions while cooling measures were tested at the beach volleyball.

The Tokyo 2020 Olympics are due to open on July 24 next year.

Among the measures being considered to combat the problem is allowing fans to bring their own bottled water into venues under certain conditions, which had previously been banned at past editions of the Olympic Games due to security and sponsorship reasons.

Misting sprays, air-conditioned tents and special road coatings are other plans put forward by organisers, as well as moving some events to earlier in the day. 

Dutch Chef de Mission Pieter van den Hoogenband, who faced the media on behalf of attending National Olympic Committees (NOCs), said he was impressed with how organisers were handling the issue.

“Of course we know there are some heat issues but overall, for all the different teams, these are the circumstances and we have to deal with it,” the triple Olympic champion said to Reuters.

“Top athletes know that they have to perform in any circumstances.

“Because of the test events, we get a lot of information and a lot of data and the way the Organising Committee is taking all that data to make it even more perfect…

“I was impressed with the way they handled things.”

Organisers have also pledged to install triple-layer screens in Tokyo Bay to combat bacteria in the water.

It comes after the discovery of E.coli which forced the cancellation of the swimming leg at the Paratriathlon test event.

The three-day Seminar continues tomorrow with every NOC invited to attend.

Representatives from the IOC and the Association of National Olympic Committees are also present.

A full progress update has been promised as well as a venue tour.

Tokyo’s Fukushima cesium-enriched microparticle (CsMP) update

CsMP-01-2.jpgSecondary electron images from Utsunomiya et al. 2019, of CsMPs discovered in atmospheric particles trapped on a Tokyo air filter from March 15, 2011, with major constituent elements displayed. 

 

August 17th, 2019

An interesting paper  was recently published by a team headed by Dr. Satoshi Utsunomiya of Kyushu University on the subject of Fukushima-derived cesium-enriched microparticles (CsMPs). As many readers will know, several researchers have located and analyzed these microparticles, in which the cesium is often bonded within glass-like silicates and therefore generally significantly less soluble than other Cs chemical species in water, though technically not actually “insoluble.” After an accident like Fukushima, it is much more common to find cesium in water-soluble compounds like cesium hydroxide (CsOH), and predictions about how quickly the cesium will be dispersed through the environment, in soil, in watersheds, taken up by plants and animals, etc, are based primarily on this assumption. The discovery of sparingly-soluble Fukushima-derived cesium microparticles, first documented by Adachi et al in 2013, and since then confirmed by many others, has raised a number of questions. How abundant are they? Does their presence increase health risk to humans? How much do they reveal about the process of the accident itself? From the standpoint of researchers the microparticles are very intriguing.

Utsunomiya et al.’s paper is titled “Caesium fallout in Tokyo on 15th March, 2011 is dominated by highly radioactive, caesium-rich microparticles,” and as noted in a recent Scientific American article, it was originally accepted for publication in 2017 by Scientific Reports journal. Weeks before publication, however, Tokyo Metropolitan Industrial Technology Research Institute (TIRI), operated by the Tokyo Metropolitan Government, raised objections with Scientific Reports. However no questions about the quality of the science or the validity of the paper’s findings appear to have been brought forward. This in itself was highly irregular. Two years elapsed without resolution, and in March of this year Scientific Reports took the highly unusual step of withdrawing its offer to publish the paper, despite the lack of confirmed evidence that would warrant it. Utsunomiya and several co-authors decided that the best course of action was to place the study in the public domain by publishing it via arXiv, a highly respected pre-print website. The paper is now open and free to download

This study makes a valuable contribution to the body of scientific literature regarding the consequences of the Fukushima disaster in general and CsMPs in particular. I think it was a mistake for Scientific Reports not to publish it two years ago, especially considering the rapid pace of research into these particles and the tremendous interest in them. To summarize the findings briefly, the researchers analyzed air filter samples from March 15, 2011, in Setagaya, Tokyo, when the radioactive plume from Fukushima caused a noticeable peak in airborne radioactivity in the city. The researchers used radiographic imaging (placing the filters on a photographic plate) to identify any highly radioactive spots. Using these images as a guide they were able to isolate seven CsMPs, which they subjected to atomic-scale analysis using high-resolution electron microscopy (HRTEM) to identify their nano-scale structure and chemical composition. Based on these detailed measurements and quantitative analysis, the researchers concluded that 80-89% of the total cesium fallout in Tokyo that day was in the form of highly radioactive microparticles. The second half of the paper is devoted to estimates of how long such particles might be retained in the human lungs if inhaled, based on previous studies that reported the effects of inhalation of non-radioactive atmospheric particles, and some possible physical consequences. The paper is valuable for the quantitative analysis of the Tokyo particles alone, since it is one of few studies that deal with the issue for Tokyo specifically. Research into possible health consequences of the particles, meanwhile, has gained momentum while the paper remained unpublished, using approaches such as stochastic biokinetics, and DNA damage studies.  In a recent paper, Utsunomiya and colleagues produced estimates of the rate of dissolution of the particles inside the human lung, in pure water, and in seawater. A working group at the Japan Health Physics Society has also devoted attention to the issue, noting the need for further study of the risk from intake of these particles, particularly to the lung.  Likewise, others have been studying the particles to learn about the accident progression and possible consequences for decommissioning.

Why did Tokyo Metropolitan Industrial Technology Research Institute object to the paper’s publication? When we first heard that publication of the paper was being held up by Tokyo Metropolitan Government, we thought politically-motivated suppression was a likely explanation. Since then the public has learned that the actual complaint given to Scientific Reports stems from a chain of custody issue of the original air filter samples. We don’t want to speculate further about Tokyo’s motivation, because we have seen no direct evidence yet of political suppression in this case. But based on past occurrences with other government institutions, we would find it plausible. We will let readers know if TIRI responds to our inquiries.

We spoke with Dr. Utsunomiya and co-author Dr. Rodney Ewing recently. I was aware of their co-authorship of several strong papers on CsMPs, including Utsunomiya’s plenary talk at the Goldschmidt Conference in Yokohama in 2016, which I attended. I asked how this new arXiv paper fits in with their other papers, and where they think this research is heading next:


Satoshi Utsunomiya:

Thank you for asking. The Tokyo paper was actually our first paper regarding CsMPs. As I mentioned, the paper was accepted two years ago. There were no previous papers of ours on CsMPs that time. Currently we are working on several topics on CsMPs. I cannot reveal the content yet, as we are thinking about a press release for the next paper. But I think it is important to continue this kind of research, providing some insights for decommissioning at Fukushima Daiichi Nuclear Power Plant.

Azby Brown:

I didn’t realize that this was your first paper on the subject.  How does it relate to the one presented at the Goldschmidt Conference in Yokohama in 2016? “Cesium-Rich Micro-Particles Unveil the Explosive Events in the Fukushima Daiichi Nuclear Power Plant.” Didn’t that paper receive a prize?

SU:

My talk at Goldschmidt briefly covered the story described in the two papers that were accepted for publication at the same time. One was published in Scientific Reports. The other one was not published. There was no prize. It was a plenary talk.

AB:

I see. I recall that it received a lot of attention. Now it makes more sense to me.

Can you tell me a little bit about the specific characteristics and focus of your research, and how it differs from papers like Adachi 2013, Abe 2014, etc? Generally speaking, that is. I’d like to help people understand the different aspects of the field.

SU:

Adachi reported the discovery of CsMPs. Abe demonstrated X-ray absorption analysis on the CsMPs. We focused on the nanotexture inside CsMPs. We are particularly interested in the detailed evidence remaining within the microparticle, which can provide useful information on the development of the chemical reactions during the meltdowns, because it is still difficult to directly analyze the materials inside the reactors. We, for the first time, succeeded in performing isotopic analysis on individual CsMPs. More specifically, the occurrence of uranium can directly tell the story of how the fuel melted. Our research has two directions: one is to understand the environmental impact of CsMPs, and the other is to provide useful information on the debris properties to help decommissioning at FDNPP. We are also interested in the implications for health.

AB:

Can you tell me a little bit about your working relationship? Satoshi went to the US to work in your lab, right Rod? When was that, and what were you working on?

Rod Ewing:

Satoshi and I have known each other since 2000, when he joined my research group as a post-doctoral fellow at the University of Michigan. He was a member of the research group until 2007. We collaborated on a wide range of topics that had to do with radioactive materials, such as the transport of plutonium at the Mayak site in Russia to the identification of uranium phases within C60 cages, so called buckyballs, that were formed and released from coal power plants. Once Satoshi returned to Japan to take his position at Kyushu University, we continued to collaborate, particularly on topics related to Fukushima Daiichi.

AB:

How did you both get interested in CsMPs?

RE:

Once discovered, CsMPs were clearly of high interest. They had not been noted in earlier reactor accidents. Satoshi is a master with the transmission electron microscope – exactly the tool/technique needed to study these particles.

AB:

For people who aren’t familiar with what’s involved in a research experiment like yours, can you describe the overall process? What were the technical challenges?

RE:

I would just emphasize that it is very difficult to find and characterize these particles. Considering the full literature and efforts by others as well as our team – the results are impressive. It is rare to have both the TEM characterization and the isotopic data.

SU:

As Rod mentioned, it is difficult to obtain both TEM and isotopic data from a few micron-sized spots. The isolation of CsMPs from soils is a time consuming process. But to date, many scientists have found and isolated CsMPs. The important thing is what information we can obtain from the analysis of CsMPs. We have been taking various approaches to elucidate the properties, environmental impact, and the role in releasing fissile actinides to the environment.    


As described above, many papers examining various aspects of Fukushima-derived cesium microparticles have been published since they were first identified in 2013. Even so, important aspects remain only partially documented and understood to date. Below is a partial list of relevant publications.

Displaced Fukushima sake brewery to restart in hometown using only local rice

If you have a death wish, make sure to drink Fukushima sake….
ghjhlkjmlmù.jpg
Daisuke Suzuki is seen working at a tank in his brewery in Nagai, Yamagata Prefecture, on July 2, 2019.
August 17, 2019
NAGAI, Yamagata — A local brewery intends to restart some of its sake making business in its hometown of Namie, Fukushima Prefecture, in two years. Its storehouse there was swept away by the tsunami that followed the Great East Japan Earthquake in March 2011 and forced the company to relocate to nearby Yamagata Prefecture.
The Suzuki Brewery is looking to hire up to two people to work in Fukushima, and will employ them first in Yamagata Prefecture from fall this year for training.
Although part of Namie is still under evacuation orders due to the effects of the nuclear meltdown at the Fukushima Daiichi Nuclear Power Plant, the company’s head, Daisuke Suzuki, 46, says he wants to work to eradicate the rumors about rice cultivated in Namie by using it as the sole ingredient in its sake.
The Suzuki Brewery was a well-known business in the port town of the Ukedo district with a history stretching back to the Edo period. Its representative sake brew, “Iwaki Kotobuki,” held a special place in the community as a drink used to celebrate big catches of fish.
Over 150 people, close to 10% of Ukedo district’s population, were killed by the tsunami in March 2011. The hydrogen explosion that occurred in the aftermath of the disaster at the Fukushima Daiichi plant some 5 kilometers south of the town meant that for around a month search and rescue activities could not proceed.
The wave also took the Suzuki Brewery and its storage out to sea. Although none of its staff were harmed, the nuclear disaster combined with the order to completely evacuate the town forced the company to give up on rebuilding the brewery in Namie.
While the town was left in a state of crisis regarding whether it would continue to operate or not, Suzuki was encouraged by acquaintances at a Fukushima Prefecture elementary school, where they were temporarily taking shelter, to continue making sake for the community. The experience made him realize that Iwaki Kotobuki sake is an indispensable part of the local community.
In October 2011, he took up ownership of a brewery marked for closure in Nagai, Yamagata Prefecture, and from November the following year he began brewing there.
Coincidentally, some of the yeast necessary to make the Iwaki Kotobuki sake had been left in the care of the Fukushima technology support center, who had been asked to analyze it before the disaster took place.
The company completed its first shipment within the year on time, and residents who bought the sake to welcome the New Year even made the news.
Evacuation orders were finally lifted for the Ukedo district and other primarily central parts of Namie in March 2017. Suzuki decided he would restart brewing activities in Namie while also keeping the business running in Nagai.
The new storehouse will be some kilometers inland from the location of the previous one, and the intention is for all of the sake’s ingredients to come from produce made in Namie, including products for home consumption such as the locally grown Koshihikari rice. Since the nuclear disaster, food made in Fukushima has suffered from rumors about its safety, but local sake is appreciated all over the country.
Although it’s considered difficult to make the necessary malted rice for sake from edible rice Suzuki is unfazed, “If we spend a lot of time and care on the work, we’ll get it done,” he said, aiming to become a beacon for the town’s rice that could lead to greater sales of the region’s products.
The company is seeking to hire one or two people up to around the age of 30. Experience or a specific gender is not required. The position will offer involvement in both sake production and the development of new products. The individuals hired will begin working at the company’s location in Yamagata Prefecture to become experienced in sake making.
“It’s low-profile work, but you get out of it what you put into it. I’m waiting to hear from people who feel they want to work together with us in Namie,” said Suzuki. The brewery can be contacted by telephone on 0238-88-2224, in Japanese only.

Fukushima 2020 Olympics Nightmare: Is PM Abe Criminally Insane?

 

Jul 28th, 2019
This documentary investigates and exposes the plans of Japanese Prime Minister Shinzo Abe to bring the Olympics baseball games to contaminated Fukushima. Although there is over a million tons of tritium radioactive water in tanks surrounding the plan, thousands of contamined bags of waste and melted nuclear rods still in the broken plants Abe has claimed to the Olympic Committee and world that Fukushima has been decontaminated.
This 2019 documentary looks at the plans of Japan Prime Minister Shinzo Abe to bring the Olympic baseball games to Fukushima during the 2020 Japan Olympic games. It interviews experts, community activists and trade unionists about the reality of Fukushima and the massive propaganda campaign to cover-up the continuing dangers and crisis.
 
PM Abe told the International Olympics Committee that Fukushima had been decontaminated but there is over 1 million tons of tritium radiocative water in tanks surrounding the broken nuclear reactors, the melted nuclear rods still remain and there are tens of thousands of bags of contaminated radioactive material spread throughout the prefecture.
 
This documentary hears from people in Japan about the reality of having the 2020 Olympics in Japan and Fukushima.

Fukushima village hit by 2011 meltdowns starts raising dairy calves again

Hopefully that milk from these local dairy farms will NOT end up in school lunch…

safe_image.php
A dairy calf is led off a truck in the village of Iitate, Fukushima Prefecture, on July 16, 2019.
July 25, 2019
IITATE, Fukushima — Local farmers have resumed raising dairy calves for the first time in over eight years in this village that was hit by radiation following the March 2011 meltdowns at Tokyo Electric Power Co. (TEPCO)’s Fukushima Daiichi Nuclear Power Station.
Feliz Latte, a dairy company jointly managed by five farmers who were forced to evacuate from areas hit by the nuclear disaster, transported its 22 calves aged 8 months to a cowshed operated by a village-run company on July 16.
The dairy company was established in the city of Fukushima using subsidies from the national and prefectural governments to promote reconstruction in the area following the Great East Japan Earthquake and tsunami, which triggered the meltdowns.
The firm plans to raise the calves in the village until they reach 22 months old and then move them to its farm in the city of Fukushima.
Prior to the disaster, the village had a total of 12 dairy farmers who used to raise about 240 dairy cattle. However, all of the farmers evacuated from Iitate due to the disaster. The evacuation order was lifted in 2017 for most parts of the village.
Kazumasa Tanaka, 48, president of Feliz Latte, said, “I hope to help the reconstruction by creating an environment where young people can easily engage in dairy farming when they return to the village.”

Temporal variation of radionuclides contamination of marine plants on the Fukushima coast after the East Japan nuclear disaster

Bioaccumulation_in_the_sea
July 16, 2019
As a result of the Great East Japan Earthquake and associated tsunami in March 2011, the Fukushima Daiichi Nuclear Power Plant (FDNPP) released a large amount of radioactive materials into the environment, resulting in contamination of many marine organisms.
In this study, 15 marine algal and a seagrass species were collected from the sublittoral zone of the Iwaki Coast of Fukushima Prefecture from May 2012 to June 2015 and analysed for variations in 110mAg, 134Cs, and 137Cs with time.
The results indicated that (1) 110mAg, 134Cs, and 137Cs were present in all marine plants collected in May 2012; (2) the concentration of 110mAg in the seagrass Phyllospadix iwatensis decreased significantly with time, while the ecological half-life of 110mAg in P. iwatensis was longer at locations closer to the FDNPP; and (3) the 110mAg/137Cs radioactivity ratio of P. iwatensis was remarkably high until 2015, indicating that detectable 110mAg was present in the coastal environment 4 years after the accident.
The concentration of 110mAg in P. iwatensis was higher than those in other marine algae, demonstrating a species-specific mechanism of accumulation.

Workers Enter Fukushima Electrical Room In Socks, Get Contaminated

workers
June 25, 2019
This unusual event at Fukushima Daiichi took place in early June. Workers entered a 2nd floor electrical room in the unit 4 turbine building in their socks. The room holds electrical equipment for the nearby reverse osmosis water filtration system. The equipment in this room is all new, post disaster equipment. The room appears to be a “clean” area where they attempt to keep dust and contamination out of the room.
 
To keep the room clean, workers are expected to change into shoes placed for use in the electrical room to prevent dust and radioactive contamination from entering the room. Instead of switching shoes, five of the ten workers removed their shoes and entered in their socks. TEPCO reports the act of opening and closing the door allowed dust to enter the room. When the workers entered in their socks they picked up contaminated dust on their socks.
 
The contaminated socks were discovered as workers were scanned at the workers facility. The inside of the shoes they wore that day were contaminated. Everywhere they walked in their socks in the worker facility was also potentially contaminated. TEPCO had to track down the shoes these workers wore by scanning all shoes of those sizes until they found the contaminated ones.
 
TEPCO did not clarify if there was a lack of enough pairs of shoes or if they were not proper sizes to allow all of the workers to use them. TEPCO is now reviewing the shoe inventory for this room to assure there are enough available for workers to change shoes. Training and new notices about work processes are being added to avoid a repeat problem. Radioactive dust on site can contain insoluble microparticles and alpha radiation. These are an inhalation hazard as well as a problem of external exposure if they become attached to the skin or hair.

Novellas express anger after Fukushima disaster

sacred cesium and isa's deluge“Sacred Cesium Ground and Isa’s Deluge: Two Novellas of Japan’s 3/11 Disaster,” by Yusuke Kimura, translated by Doug Slaymaker (Columbia University Press, 2019, 176 pages, $60 hardcover, $20 paperback)

May 2, 2019
TOKYO >> An anger directed toward Tokyo underlies Yusuke Kimura’s two novellas, “Sacred Cesium Ground” and “Isa’s Deluge.” Born from a keen sense of abandonment felt by the Tohoku region in the aftermath of the catastrophic earthquake and tsunami on March 11, 2011, and the subsequent nuclear accident at the Fukushima Daiichi Nuclear Power Plant, this anger plays out across stories exploring the post-disaster relationships between humans and animals.
The protagonist in “Sacred Cesium Ground” is a woman who travels to Fukushima Prefecture to volunteer at the Fortress of Hope, a farm where cattle irradiated by the Fukushima No. 1 power plant meltdown are tended to despite a government order to kill them.
Based on the story of a real post-Fukushima ranch, the novella carries with it a weight of research born from the author’s own volunteering, though it proves ultimately unsatisfying, never quite reaching the moment of reinvention that the lead character hints at throughout.
“Isa’s Deluge” is the more readable of the two, with a flow and pacing that draws in the reader. Shortlisted for the Mishima Yukio Prize after it was first published in 2012, it follows a family of fishermen who relate the story of their uncle Isa and his “deluge” of pain and depression, an allegory of the 3/11 tsunami.
Both novellas highlight peripheral voices in the post-3/11 period and ultimately return time and again to that tension between a “sacrificial” Tohoku and an all-powerful capital. These perspectives are those not frequently heard and challenge the widespread narrative of an ever-dominant Tokyo.

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?

Determination and Comparison of the Strontium-90 Concentrations in Topsoil of Fukushima Prefecture before and after the Fukushima Daiichi Nuclear Accident

serveimage
Abstract
To precisely understand the status of scattered strontium-90 (90Sr) after the 2011 accident at the Fukushima Daiichi Nuclear Power Plant (F1-NPP) of Tokyo Electric Power Company (TEPCO), the measurement of the soil samples collected both before and after the day of the accident from the same sampling locations is necessary. However, very few reports have investigated the background contaminant data before the accident even though several studies have been conducted to investigate the effects of the F1-NPP accident. To address the lack of the passed 90Sr information and reestablished baseline, this study focuses on the stored topsoil samples that are collected from the same sampling locations from the Fukushima Prefecture before and after the F1-NPP accident, which are analyzed for obtaining the 90Sr concentrations. The results of our investigation exhibited that the 90Sr concentrations in the Fukushima Prefecture soils ranged from 0.2 to 20.4 Bq/kg in the samples that were collected before the accident and from 1.37 to 80.8 Bq/kg in the samples that were collected after the accident from identical sampling locations. Further, the soil samples that were collected from 30 out of 56 locations displayed significant differences in terms of concentrations before and after the accident. In addition, the relations between the 90Sr concentrations and the soil properties of the samples (organic content, pH, water content, and composition) were investigated, and it was found that the organic content and water content had a positive correlation with 90Sr concentrations and, in contrast, the sandiness was shown to have a negative correlation with 90Sr concentrations. The depth characteristics were also investigated. The aforementioned results indicate that this tendency would be observed even in the future.
 
Introduction
 
A large amount of radioactive materials was scattered throughout the environment (ocean, atmosphere, land, and so on) because of the accident that occurred on March 11, 2011 at the Fukushima Daiichi Nuclear Power Plant (F1-NPP) that was owned by Tokyo Electric Power Company Holdings, Inc. (TEPCO).(1−3) Seven years have passed by since the accident, and research institutes around the world have been monitoring the influence of the environmental dynamics of radionuclides that have been released.(4−13) More specifically, there have been several environmental monitoring reports regarding β-ray-emitting nuclides, such as radioiodine and radiocesium, because multiple samples can be analyzed in a relatively short time using certain types of instruments such as a germanium semiconductor detector, a sodium iodide scintillator detector, and a lantern bromide scintillator detector.(14−19) Meanwhile, radiostrontium (90Sr) (half-life: 28.79 y(20)) is a pure β-ray-emitting nuclide that does not emit γ-rays, which makes it necessary to chemically isolate it for measuring β-rays because the β-ray spectra overlap. In particular, it is imperative to monitor 90Sr over a long period because it will require several decades to decommission F1-NPP. In Japan, instead of a few literature concerning the development of a rapid analytical means,(21−25) radiochemical analysis using milking-low background gas-flow counter (milking-LBC) is adopted as the official analysis method for analyzing 90Sr because of good sensitivity and/or high-precision analysis in low concentration levels in the environment.(26) This method requires considerable amount of time and effort to pretreat the analysis as compared to those required by the γ-ray measurement method. Although various studies have been vigorously conducted,(27−33) the study related to the scattering of 90Sr is not as advanced as compared to that related to the γ-ray-emitting nuclides such as radiocesium.
To precisely understand the status of scattered 90Sr after an incident of nuclear accident, the samples collected both before and after the day of the accident should be measured, thereby distinguishing from the fallout of atmospheric nuclear tests (20th century’s) that have been conducted in the past. So far, the survival ratios of nuclides with short half-lives in samples have been employed in several studies.(34) However, this technique cannot track the long-term process because it becomes difficult to evaluate the nuclides that exhibit a short decrease in half-lives. The optimal method for addressing these issues is to measure the radioactive concentrations of 90Sr in soil that is collected at identical locations before and after the accident. However, few examples exhibited the presence of 90Sr in soil before the F1-NPP accident, which was completely unexpected. Fortunately, we already possessed analytical data related to the 90Sr concentrations in soil samples that were collected before the accident with precise sampling locations throughout the Fukushima Prefecture (not published). Therefore, in this study, we succeeded in estimating the exact amount of 90Sr deposition before and after the F1-NPP accident. When performing the long-term observation, understanding the background level of 90Sr before the accident was observed to be considerably important for understanding the environmental radioactivity and the environmental dynamics or the usage of 90Sr as a tracer.
In this study, we measured the radioactivity concentrations of 90Sr in the topsoil at the same locations in the Fukushima Prefecture before and after the accident and obtained the background levels of 90Sr before the F1-NPP accident. Thus, we revealed the deposition status of 90Sr before and after the accident. We also investigated the correlation between the soil properties and 90Sr to determine the status of deposition of 90Sr on the topsoil in Fukushima prefecture (Figure 1).

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.
