“The agreement is very assuring, as we will be able to receive support for efforts on the safety and security of the region,” Gov. Masao Uchibori said during the signing ceremony at the prefecture’s office on the same day.
It is the 15th time the unit of Japan Post Holdings Co. has concluded an agreement with a prefectural government.
Under the plan, Japan Post’s delivery minivehicles will be equipped with radiation gauges. Data will be collected automatically and wirelessly transmitted to the prefectural government. The prefecture’s coast was heavily damaged by the March 2011 mega-quake and tsunami, while much larger parts of it were contaminated by radiation by the subsequent core meltdowns at the Fukushima No. 1 nuclear plant, run by Tokyo Electric Power Company Holdings Inc.
In addition, the two parties agreed that posters to promote Fukushima goods will be put up at post offices in areas around Tokyo, in Fukushima and five other prefectures in the Tohoku region.
Japan Post’s delivery staff will also alert the prefectural government and others when several days’ worth of newspapers are seen accumulating outside of the homes of elderly people, and when damage to roads is observed.
“We will provide maximum assistance for Fukushima Prefecture’s revitalization,” said Kunio Yokoyama, president of Japan Post.
More workers tested positive for Hanford radiation, The 6 people are added to 31 who tested positive for inhaling or ingesting contamination in June, February 15, 2018 By Annette Cary / Tri-City Herald
Another spread of radioactive contamination has been confirmed at the Hanford nuclear reservation’s Plutonium Finishing Plant.
In addition, more central Hanford workers have tested positive for inhaling or ingesting radioactive contamination from demolition of the plant.
For the second time since workers were moved in January to offices away from the plant, contamination has been found on the steps of the newly assigned offices.
Most recently, a spot of radioactive contamination described as about the size of a 50-cent piece was found on the step outside an office on Feb. 8. The step has been removed.
In some cases radiation detected at Hanford is determined to have come from naturally occurring radon, but in this case it appears to be related to demolition of the heavily contaminated plant.
Demolition and the packing and hauling away of the debris has been stopped at the plant since mid-December after a spread of particles of radioactive contamination was discovered.
Most of the demolition of the Plutonium Reclamation Facility, the most contaminated portion of the plant, had just been completed when the spread was found.
Several steps have been taken since December, including bringing in new contractor management for the project, widely expanding the area where access is controlled and moving workers from offices near the plant to offices outside the control area.
Workers take shuttles to and from the plant, as needed for work assignments, from their newly assigned offices.
In response to the first discovery of a spot of contamination outside the new offices in late January, more stringent rules were instituted for checks of workers leaving radiologically contaminated demolition areas.
In response to the Feb. 8 spread, the radiological buffer around areas where radioactive material is expected to be present has been expanded. Workers have their hands and feet checked for radiation when they leave that area to board a shuttle to offices.
The number of workers known to have inhaled or ingested radioactive particles has increased to six.
Some 212 workers who requested checks had no contamination, with about 60 checks pending. Bioassays, or checks of body waste, are being done to determine if workers have radioactive contamination inside their bodies.
The amount of internal contamination is small. The largest estimated radiation dose for the six workers is 10 to 20 millirem over 50 years.
In comparison, the average person in the United States receives about 300 millirem a year annually from natural background radiation, including radon or radiation bombarding the Earth from outer space.
The six workers with positive bioassay results are in addition to 31 workers who tested positive for inhaling or ingesting radioactive contamination from Plutonium Finishing Plant demolition in June. The highest estimated dose from June was 10 millirem total over 50 years.
The worker tested positive for inhalation of the potential lethal nuclear isotope of plutonium – a key ingredient to the production of nuclear bombs and warheads., KGW8 News: Susannah Frame, February 13, 2018 A Hanford worker directly impacted by safety failures at an extremely dangerous demolition project at the site has granted an interview to KING 5.
The worker tested positive for inhalation of the potential lethal nuclear isotope of plutonium – a key ingredient to the production of nuclear bombs and warheads.
“I’m pissed. I’m scared, like we all are, that sooner or later it’s going to bite me and I’m going to end up with cancer,” said the contaminated worker.
For fear of retaliation, the worker does not want to be identified. Eight months ago, on June 8, the person was one of hundreds working on the demolition of Hanford’s Plutonium Finishing Plant (PFP). The workers were told to ‘take cover’ as a ‘precaution’ because monitors detected radioactive plutonium particles could be in the air.
But the event ended up not being precautionary whatsoever. The contractor in charge of the demolition, CH2M Hill, had an enormous problem on its hands.
“It was complete chaos. It was a mess,” said the worker.
Indeed, radioactive particles had escaped and spread outside the demolition zone. Hundreds of workers were eventually tested. Thirty-one of them got bad news: They had inhaled or ingested plutonium, which emits alpha radiation, the worst kind of radiation to get inside your body.
“Plutonium will go to the bones and sit there for a long, long time,” said Dr. Erica Liebelt, a toxicologist and executive director, as well as medical director, of the Washington Poison Center.
“Your risks are lung cancer, liver cancer, and bone cancer. That’s where plutonium heads in the body.” “(After being told no one was hurt) I was angry. You carry that with you for the rest of your life. It’s a cancer causer,” said the worker interviewed by KING 5.
After that event in June CH2M Hill increased safeguards and promised to do better. But six months later the job got out of control again. More plutonium began escaping outside the demolition control zone on December 15. Instead of getting to the bottom of it right away, CH2M Hill waited two days to halt the job.
Radioactive particles ended up on all kinds of items including worker’s boots, office trailers, jersey barriers, tumbleweeds.
“The response was awful. To me (waiting was) unforgivable, inexcusable. That should never have happened and this contractor ought to be on the hot seat,” said Tom Carpenter, executive director of the advocacy group Hanford Challenge.
The plutonium spread also made it onto cars. The KING 5 Investigators have found 36 cars total. Seven of them were personal vehicles, driven off the site by unsuspecting employees. The vehicles, with contamination on them, were driven into town and to their homes. One of those cars belongs to the worker who was contaminated internally six months earlier. …..
Once you have contamination that gets on private party’s cars and then gets driven off the Hanford Site it’s a big concern for us,” said Alex Smith of the Washington state Department of Ecology. Smith is the state’s top-ranking regulator for the state over Hanford.
On January 9, the Department of Ecology and the EPA sent a joint letter to U.S Department of Energy officials to communicate their great concern. For the first time in Hanford’s history, the regulators enacted a provision allowing them to halt work on a project due to a “creation of danger” to people and the environment.
ASCO GU 2018: Diagnostic Radiation and Testicular Germ Cell Tumor Risk Uro Today, 18,San Francisco, CA (UroToday.com)Dr. Kevin Nead and colleagues presented their work assessing diagnostic radiation and testicular germ cell tumor risk. Dr. Nead notes that both the incidence of testicular germ cell tumors (TGCT) and use of diagnostic radiation have increased in recent decades. In a quarter of diagnostic scans in children, direct and indirect radiation dose to the testes exceeds 20 mSv, which surpasses thresholds associated with malignancy risk (~5 mSv). The objective of this study was to examine the association between exposure to diagnostic radiation and TGCT risk in a case-control study. ……. The authors concluded that exposure to diagnostic radiation below the waist, particularly among younger individuals, may increase TGCT risk. ...https://www.urotoday.com/conference-highlights/asco-gu-2018/asco-gu-2018-penile-urethral-testicular-and-adrenal-cancers/101967-asco-gu-2018-diagnostic-radiation-and-testicular-germ-cell-tumor-risk.html
A better direction for low-dose radiation research, BAS, Jan Beyea 12 Feb 18,
With bipartisan support, the US House Science, Space, and Technology Committee recently passed a bill to revitalize low-dose radiation research. The bill, which would authorize an estimated $96 million in funding, has also garnered support from researchers and groups with opposing views on the seriousness of effects of ionizing radiation in the low-dose region, defined as being below 100 millisieverts—roughly the amount of radiation from 10 CT scans.
Studies of excess cancers among survivors of the Hiroshima and Nagasaki bombings have estimated a 1 percent increase in long-term cancer risk for adults receiving a dose of 100 millisieverts (the risk is higher for children), with the risk below that level declining in proportion to the dose. However, stakeholders and researchers with different hypotheses continue to debate whether or not downward extrapolation by dose magnitude—the “linear no-threshold” model deemed most reasonable by a National Research Council committee of experts—is the best way to estimate risk. ……
The hope of many supporters of the proposed legislation, voiced by Rep. Roger Marshall, a Kansas Republican, is that it may assist “the development of nuclear energy opportunities,” in part by reducing the size of nuclear plant evacuation zones. The bill’s supporters presume that the finding of a threshold or hormesis region would demonstrate that the existing linear no-threshold model is an over-protection that, as Northwestern University radiation biologist Gayle E. Woloschak wrote in a letter of support for the bill, “may be wastefully expensive and deplete funds that could be used for other strategic goals for the nation.”
Past research by the Energy Department to upend the linear model has failed to fulfill that dream, finding health effects below 100 millisieverts from even protracted exposures. There is so much existing epidemiological data from exposed workers, patients receiving medical diagnostics, and residents living around the Soviet nuclear complex—as well as the Japanese atomic bombing survivors—that new research, whatever it shows, will need to be interpreted in the light of all the evidence.
That will likely leave stakeholders and experts debating for a long time, and the public confused.
Inherent uncertainty. New radiation research is likely to carry uncertainties, which means government policy must be conservative in its choice of the best dose-response model to use. Why is it difficult to tease out risks at low doses? Individual risks from medical diagnostics and from the (fortunately) limited releases of radioactivity at Fukushima are generally low under the linear extrapolation model. They are small compared with background disease rates, challenging epidemiological methods. The difficulty of finding effects among background cancers is actually good news for exposed individuals. However, the social risk is sufficiently large to justify keeping doses as low as reasonably achievable and balancing risks against benefits.
My colleagues and I call radiological events “reverse lotteries”: The individual risk of drawing a cancer-causing “ticket” from an event such as the Fukushima meltdowns is small, but because so many people are part of the lottery, real people do get impacted when they draw losing tickets.
Prospective risks and retrospective risks are perceived differently. If I learned that my family and I had already been exposed to a 1-in-1,000 cancer risk, I would be angry, but I would realize that the odds were highly in our favor; none of us would likely be injured. However, if you asked me to relocate to contaminated land where my children would be exposed to a 1-in-1,000 chance of cancer, I would want to stay away unless there were major benefits associated with the move, or if I thought I couldn’t afford to do otherwise. Risk tradeoffs are personal, and families can be painfully split on the best decision, as happened at Fukushima……… https://thebulletin.org/better-direction-low-dose-radiation-research11500
And the beneficiaries are and will be hundreds, if not thousands, of workers exposed to some of the most dangerous materials known to humans.
The workers are present workers and retirees, at the Department of Energy’s nuclear complex in Hanford, Wash. And as a result of all those factors, they’ll be more eligible for workers’ comp.
The story starts in 1942-43, says Nick Bumpaous of Plumbers and Steamfitters Local 598, located near the complex. That’s when the U.S. War Department took over the Hanford area to build the factory complex to make nuclear warheads for U.S. bombs. Hanford, like the whole Manhattan Project for developing atomic weapons, was top secret.
The feds, to their credit, realized Hanford’s workers would be in constant daily contact with uranium, plutonium and other highly radioactive materials. Who knew what would happen to them in later years due to those exposures?
“In the 1940s, the War Department got into a contract with the state legislature to have workers use Washington’s industrial insurance for workers’ comp claims if they got ill from handling the radioactive material,” Bumpaous said in a phone interview. “The feds would reimburse the state for any claims.”
The catch was when sickened workers went to their doctors, the doctors “couldn’t tell what the illnesses were” – because Hanford was secret – “so they couldn’t give you medication,” much less OK workers’ comp claims.
Common diseases among the Hanford workers include various cancers, according to a fact sheet for a later federal workers comp program for federal nuclear workers nationwide. The Steelworkers, who now represent many of those nuke workers, lobbied for and won the federal program. It began in 2001, with a second part added in 2004. But it caps lifetime benefits at $250,000, plus medical expenses.
“But you still put the burden of proof” upon the worker to show his or her toil at Hanford and exposure to the fissile materials there caused those ills, not to mention exposure to other threats, Bumpaous says.
One example: Exposure to diethyl mercury, “a silent odorless, colorless, tasteless stuff that induces neurological diseases and dementia.” In addition, “you have a whole generation of people with reactive airway disease,” he adds.
The doctors couldn’t diagnose the reasons for Hanford ills. The workers became so ill they couldn’t work and had to leave their jobs, “so they’re not getting a paycheck and they had no health insurance.” They had to navigate the bureaucracy “and their claims were denied,” Bumpaous explains. Workers’ comp denials at Hanford were 52 percent above average.
“It’s hard enough to take care of yourself when you’re battling the Department of Energy,” which now runs Hanford “and the state Department of Labor and Industry,” which runs workers’ comp, Bumpaous says.
With the burden of proof on the workers, Bumpaous got into the picture. Two years ago, he read about legislation the Fire Fighters successfully pushed elsewhere, shifting the burden of proof for certain diseases – known to be caused by Fire Fighter exposure to asbestos and other dangers on the job – from the worker to the state.
In short, if a Fire Fighter goes to the doctor with asbestosis, the doctor must presume the worker caught it from on-the-job exposure and is eligible for workers’ comp. Bumpaous wanted to create the same scenario for the Hanford workers. Workers and retirees still must go to the doctors, though.
“These brave workers continue to be exposed to some of the most hazardous substances known to man, including many chemical and radiological hazards as yet unidentified, and the safety measures intended to protect them are inadequate,” wrote David Groves in The Stand, the Washington State Labor Council’s online newspaper, which first reported the legislation.
But the Hanford workers couldn’t get workers comp because they had to “connect specific exposures to their disease — a virtually impossible task given the” top secret “circumstances at Hanford.”
Bumpaous enlisted two lawmakers to push the measure shifting the burden of proof from the workers to the state: State Rep. Larry Haler, R-Richland, and State Sen. Karen Keiser, D-Kent, a longtime pro-worker advocate, who is now state Senate President Pro Tem and chair of the state Senate’s Labor Committee. Haler’s district includes Hanford.
And that’s where the political switch comes in. When Bumpaous, Haler and Keiser first tried to get their bill, HB1723, through, it passed the House, then died in the Senate, which the GOP controlled by one vote. Republican leaders wouldn’t even let it get out of committee.
But earlier this year, Manka Dhingra, a Democratic pro-worker woman with strong union backing, won a special election for an open State Senate seat. Control switched, Keiser took over – and the legislation for the Hanford workers sailed through: 76-22 in the House and 35-14 in the Senate.
“It’s important we take care of workers who suffered due to being exposed to harmful chemicals and processes at Hanford,” Haler said. “Despite all the safety precautions, families and individuals have been devastated by illness and disease. They need help. This will help make that easier,” Haler said after HB1723 headed for Democratic Gov. Jay Inslee’s desk.
“Exposure to heavy metal and radiation has ruined people’s lives,” Keiser told the Senate before passage.
“I cannot think of a more suitable assertion for this Senate to make than putting our partisan differences aside to put people first. We are seeing people dying from dementia, cancer and lung disease who were systematically left out of workers compensation.”
“People went bankrupt paying for cancer treatments. This ordeal has been going on since the 1990s. We have seen a whole generation impacted by this tragedy. That is not right. Our Washington community cares about protecting all workers.”
Inslee is expected to sign the bill. But that’s not the end of the story for Bumpaous. “I want to see everyone get these benefits” nationwide if they worked in nuclear weapons and warhead production, he says. “That way we won’t have this type of stuff in the future.”
U.S. FDA Approves NorthStar Medical Radioisotopes’ RadioGenixTMSystem (Technetium Tc 99m Generator) for Non-uranium Sourced Molybdenum-99 (Mo-99) Production of Imaging Isotope Technetium-99m (Tc-99m)– Enables domestic Mo-99 supply produced without uranium for U.S. healthcare –
– First U.S. source of medical radioisotope Mo-99 in more than 25 years –
BELOIT, Wis.–(BUSINESS WIRE)--NorthStar Medical Radioisotopes, LLC, (NorthStar) a company involved in the production and distribution of radioisotopes used for medical imaging, today announced that the U.S. Food and Drug Administration (FDA) has approved the RadioGenixTM System, an innovative, high tech radioisotope separation platform indicated for use in producing the widely used medical radioisotope technetium-99 (Tc-99m) from NorthStar’s non-uranium based molybdenum-99 (Mo-99). The RadioGenixTM System is indicated as “a technetium Tc 99m generator used to produce sterile, non-pyrogenic Sodium Pertechnate Tc 99m Injection.”There has been no U.S. production of Mo-99, the parent isotope of Tc-99m, for more than 25 years. The supply of Mo-99 has been subject to frequent and sometimes prolonged interruptions, disrupting and often delaying the diagnosis and treatment of patients in need of medically important diagnostic tests that require the use of this radioisotope. Furthermore, current bulk production of Mo-99 is based on enriched uranium which poses significant environmental concerns.“With the FDA’s approval of the RadioGenix System, NorthStar can begin providing its customers with a reliable and environmentally friendly supply of the Mo-99 radioisotope for the United States,” said George P. Messina, Chairman and CEO of NorthStar Medical Radioisotopes. “As the first, and thus far only company to achieve the objective of being the first U.S. producer of Mo-99 in more than 25 years, we are extremely proud to pioneer domestic production of Mo-99 that is independent of uranium-based product. The approval by the FDA will reduce the U.S. healthcare system’s reliance on fragile foreign supply of Mo-99 and the use of enriched uranium target material. The RadioGenix System allows for automated, on-site separation and preparation of U.S. Pharmacopeia (USP) Sodium Pertechnetate Tc 99m Injection from Mo-99. The RadioGenix is also a platform technology that has the potential ability to apply its separation capabilities at the point-of-care to other radioisotopes in the future, including therapeutic isotopes such as actinium-225/bismuth-213 (which will require FDA approval). ……….
The RadioGenix System is an innovative, high tech system that is approved for processing non-uranium/non highly enriched uranium molybdenum-99 (Mo-99) for the production of the important medical radioisotope, technetium-99m (Tc-99m). Prior to availability of RadioGenix technology, the U.S. supply chain for Mo-99 has been subject to frequent and sometimes severe interruptions which negatively impact patient healthcare. Approved by the U.S. Food and Drug Administration in February 2018, the RadioGenix System is the first and only on-site, automated isotope separation system of its kind for use with non-uranium/non-highly enriched uranium based Mo-99. ……….. https://www.businesswire.com/news/home/20180208005961/en/U.S.-FDA-Approves-NorthStar-Medical-Radioisotopes%E2%80%99-RadioGenixTM#.Wnzqgpg9SWY.facebook

Days Past: Are you a Downwinder? , Shannon Williams, The Courier, 4 Feb 18 Downwinder: this term has become well known in Yavapai County. Downwind radiation exposure has been cited in many cancer diagnoses and blamed for the deaths of many long-term residents of the county.
How did this happen? During the Cold War, the U.S. government built a huge nuclear arsenal. Above-ground testing began in 1951 at the Nevada Test Site, where over 100 nuclear bombs were detonated through 1958. All nuclear testing stopped in 1958 by agreement among the United States, the United Kingdom and the USSR.
The government detonated several above-ground devices in July 1962. This was the last time nuclear weapons were tested above ground. Nuclear testing continued below ground at the Nevada Test Site. From Jan. 21, 1951, to Oct. 31, 1958, and June 30, 1962, to July 31, 1962, when above-ground testing was conducted, were later designated as Downwind time periods.
After the 1962 testing period, many of the workers at the test sites and local residents filed class action lawsuits alleging exposure to known radiation hazards. All of the suits were dismissed by the courts. Congress responded by creating the Radiation Exposure Compensation Act (RECA) on Oct. 5, 1990. The Act was then expanded in 2000, when the Radiation Exposure Screening and Education Program (RESEP) was created. RECA provides monetary compensation as an apology to individuals who developed certain cancers after their exposure to radiation. RECA authorized the payment of $50,000 to individuals who lived downwind from the Nevada Test Site and developed one of the specified diseases.
Congress designated several counties in Nevada, Utah and Arizona as areas impacted by the radiation exposure. In Arizona, the Downwind-eligible counties include Apache, Coconino, Gila, Mohave (above the Grand Canyon), Navajo and Yavapai………
Many local residents have been affected by these nuclear tests, as we now know. Perhaps the most well-known was longtime Prescott resident and former City Council member John Hanna, who died of non-Hodgkin’s lymphoma in October 2013 – which the government has acknowledged was likely caused by radiation from nuclear testing. Quoting from the book “Downwind: A People’s History of the Nuclear West,” by Sarah Alisabeth Fox: “Many families” in the areas affected by fallout “kept livestock and gardens or bought meat, milk, and produce from their neighbors, unwittingly gathering radiological contamination … and placing it on their dinner tables.”
To file a RECA claim, individuals need to provide documentation to show physical presence in the Downwind counties for two years during the Downwind time periods.
In addition, individuals need to establish their diagnosis of a compensable cancer. Compensable diagnoses include leukemia, multiple myeloma, lymphoma, and cancers of the thyroid, lungs, esophagus, and breast, among others. Applicants do not need to provide causation on their cancer diagnosis. They only need to gather medical records that show proof of the eligible cancer.
RECA expires on July 9, 2022. All Downwinder RECA claims must be submitted before this date.
Join Shannon Williams, health promotions manager with RESEP, when she presents “Downwinders Program: Are You Eligible?” at 2 p.m. Saturday, Feb. 10, at Sharlot Hall Museum. Come early, as seating is limited.
If Elon Musk is to colonise Mars, he’ll need to recruit a crew of genetically-modified humans
People who live on Mars may need to be genetically altered to be resistant to radiation. And while it might seem a long way off, research is already underway to work out how this can be done. Wired, ByABIGAIL BEALL, 3 Feb 18, Elon Musk dreams of creating a million-person city on Mars. But first, the SpaceX and Tesla founder is going to need a small group of people with an unusual genetic trait in common; resistance to radiation.
Radiation resistance in humans and animals is something we know little about, although we know it exists. At the moment, resistance tests are used to try and predict how much radiation cancer patients can survive, but one day this could be an important decider of who gets to venture into space.
Our Earth is protected from the harmful radiation from the Sun by our magnetic field, but astronauts that leave the planet will be bombarded with the dangerous particles…..
it’s not impossible that in the future, humans could be gene-edited to better withstand the harshness of space; not limited to the radiation. …….
The lenses in our eyes are one of the most sensitive parts of the body when it comes to exposure to radiation. Astronauts, who are exposed to dangerous levels of space radiation, and survivors of atomic bombs and accidents such as Chernobyl, have been shown to be much more susceptible to a condition called radiation cataracts.
This special type of cataract, which was seen for the first time in a rabbit in 1897, is easy to detect because it grows from the back of the lens. Exactly what causes it is unknown, but the current best explanation is that it forms because of DNA damage.
……..If radiation-resistant humans are sent to Mars, this would make an interesting pot of humans from which new traits could evolve separately from those on Earth.
NASA lecture: Radiation still a stumbling block to space travel Daily Press, Tamara Dietrich Contact Reporter, Senior Reporter, 4 Feb 18 The dream of exploring deep space has sparked the imagination for generations, but it always runs up against one cold, hard reality: radiation.
Simply put, exposure to space radiation during a long mission or while exploring a place like Mars increases the likelihood of an astronaut dying from cancer.
Yes, astronauts are willing to take some risks, but within reason, said John Norbury, lead research physicist in the Space Radiation Group at NASA Langley Research Center in Hampton.
According to the American Cancer Society, the average American male stands a roughly 22 percent chance of dying from cancer in his lifetime; an American woman, just under 19 percent.
“It’s not a do-or-die situation,” Norbury said. “It’s, rather, how much does the risk of dying from cancer increase on a mission?”……….
Senior research physicist Sheila Thibeault said “Radiation in space is much, much, much more hazardous than on Earth, so this is a space problem. And it’s a very challenging problem to try to figure out how we’re going to get astronauts to Mars and back safely. And how to get astronauts to the moon and stay there for a while and get back.” ……..
Prolonged exposure doesn’t just increase one’s lifetime cancer risk, but can cause serious acute health effects.
Cellphone radiation study finds mixed effects in rodents without clear implications for human health, WP, By Ariana Eunjung ChaFebruary 2 2018
The long-awaited results of a $25 million National Institutes of Health study on the effects of cellphone radio frequency radiation exposure on animals is out, and the results are mixed. They showed a higher risk of tumors, DNA or tissue damage and lower body weight in some groups of rodents, but no obvious ill effect in others and no clear implications for human health.
John Bucher, a senior scientist involved in the 10-year study, was cautious in his interpretation of the results in a conference call with journalists on Friday. Given the inconsistent pattern of the findings, the fact that the subjects were rats and mice rather than people and the high level of radiation used, he said he could not extrapolate from the data to potential health effects on humans.
“At this point we don’t feel that we understand enough about the results to place a huge degree of confidence in the findings,” he said.
Bucher also said “I have not changed the way I use a cellphone, no.”
The study by the National Toxicology Program is believed to be the most comprehensive assessment of the health effects of such radiation on rats and mice and involved 3,000 test animals. A draft report was released on Friday for public comment and peer review, in advance of an external expert review on March 26-28. Among other things, reviewers will examine whether some of the results might be statistical noise.
The issue of cellphone radiation’s impact on human health is one that has been hotly debated for years. In 2010, the Federal Communications Commission came under fire after it dropped a long-standing recommendation that consumers buy phones with lower radiation emissions. In 2015, the city council in Berkeley, Calif., approved a disclosure ordinance that directed sellers to let buyers know of the risk of carrying devices too close to their bodies. The CTIA, which represents the wireless industry, has sued, saying the warnings are “ill-informed” and violates retailers’ First Amendment rights.
The strongest finding in the new study involved male rats — but not female rats or male or female mice — which developed tumors in the nerves surrounding their hearts. Researchers also saw increases in damage to heart tissue in both male and female rats. If these results are confirmed, Bucher said, they appear to suggest this type of radiation could be a “weak” carcinogen.
The male rat tumors were so-called malignant schwannomas. Based on limited research that shows a potentially elevated risk of schwannomas near the brain in people, the International Agency for Research on Cancer lists radio-frequency fields as “possibly carcinogenic to humans.”
In a study published earlier this month, researchers discovered that yeasts are surprisingly capable of withstanding radioactive and acidic conditions, like those that would follow a nuclear detonation. A species of yeast called Rhodotorula taiwanensis can even form a type of shield, called a biofilm, to stop radioactivity from spreading. The reddish fungus — which Popular Sciencedubs “hardcore yeast” — was originally found in an abandoned acid mine in Maryland, and it has even proved more effective in halting radioactive spread than a microbe that researchers nicknamed “Conan the Bacterium” for its resistance to radiation.
“The potential for yeast is enormous,” said the study’s co-author Michael Daly. He and other researchers are hoping to use their newfound fungal ally to stop the leakage of Cold War-era nuclear waste, which is stored at 120 sites around the country. The largest of these, the Hanford Site in southeastern Washington, houses more than 50 million gallons of nuclear byproduct — and has contaminated 10,000 football fields’ worth of soil since it was used to assemble the first atomic bombs during the Manhattan Project.
But with the mighty yeast on their side, these scientists are hopeful that they can contain the dangerous waste. Read more at Popular Science. Shivani Ishwar
But communities around the uranium mines and test sites needed for the production of nuclear weapons — places which are often socio-economically disadvantaged already — have been especially impacted by the health and environmental costs of nuclear weapons production.
The Navajo Nation is just one example — where cancer rates doubled from the 1970s to the 1990s due to the impacts of testing, mining and milling in the southwestern US. Mining companies extracted millions of tons of uranium between 1944 and 1986. At the time, Navajo children played in mine debris piles and pools, and livestock drank contaminated water. Some homes were even built with materials from uranium mines and mills.

Runit Dome, on Enewetak Atoll, serves as a living reminder of US nuclear testing that continues to threaten the islands today. The 18-inch concrete cap covers 111,000 cubic yards of radioactive debris left behind after 12 years of nuclear tests. Today, scientists fear the effects of climate change could damage the dome, releasing its contents into the ocean.
The lands of some indigenous communities still house nuclear waste today. Tribes play host to this waste because their reservations are not subject to the same environmental and health standards as US land.
“In the quest to dispose of nuclear waste, the government and private companies have disregarded and broken treaties, blurred the definition of Native American sovereignty, and directly engaged in a form of economic racism akin to bribery,” Bayley Lopez of the Nuclear Age Peace Foundation told Scientific American, citing examples of companies taking advantage of the “overwhelming poverty on native reservations by offering them millions of dollars to host nuclear waste storage sites.”
Whether this characterization and those like it are fair, it’s an unfortunate fact that the people who live near the hallmarks of the US nuclear industrial complex — like test sites in Nevada and the Marshall Islands, mines in the western half of the US, and the indigenous communities that still house nuclear waste today — have been disproportionately affected by the cost of what it takes to keep the rest of us safe.
Morning Star 27th Jan 2018, Fury as scandal-hit nuclear agency demands 23-fold radiation emissions
increase. CAMPAIGNERS have gone nuclear after the Atomic Weapons
Establishment (AWE) applied this week to increase radiation output from its
Berkshire site by over 2,000 per cent.
AWE, which produces Trident nuclear warheads, had two sites placed in renewed special measures last August over
safety concerns. Now the company is asking the Environment Agency to raise
the 4.4 megabecquerel radiation limit to 100MBq for tests it claims will
help counter nuclear terrorism.
But the Campaign for Nuclear Disarmament
(CND) said it was nuclear proliferation that increases chances of dangerous
material falling into hostile hands. The group also sounded the alarm over
the risk to public health. CND radiation expert Ian Fairlie said: “While
radiation amounts appear relatively low in the application, they represent
a 23-fold increase. If radiation is released into the water supply in
spikes, this could present a danger.”
