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.”
The recent false alarm in Hawaii underscores the threat from nuclear devices. While there has been media attention placed on how the United States is taking military and diplomatic action against North Korea from launching a nuclear strike, there is little media attention given to how well the United States is medically prepared for a nuclear attack. According to a recent report in the Bulletin of the Atomic Scientists, U.S. cities are not medically prepared for a nuclear detonation. This report, written by Dr. Jerome Hauer, who was the former assistant secretary for the Office of Public Health Emergency Preparedness at the U.S. Department of Health and Human Services, asserts that the United States is completely unprepared to manage the aftermath of a nuclear detonation. We are at a moment in history where nuclear terrorism is an unfortunate reality. North Korea and Iran have established nuclear capabilities, and Pakistan has stockpiles of highly enriched uranium.
These countries have a history of supporting terrorist groups. It has been acknowledged by our government that highly enriched uranium can be smuggled into this country to build a 10-kiliton improvised nuclear bomb, like that dropped on Hiroshima in 1945. A nuclear threat would even include a dirty bomb that combines a conventional explosive with radioactive isotopes, which could contaminate an area and leave a residual radioactive “hot zone” that is too dangerous for even first responders to enter. Also, radioactive particles can disperse into the air and create a “plume” that could extend hundreds of miles away from ground zero and create a contamination area that would last for years.
A nuclear blast would instantly release a massive pressure wave and heat that would incinerate everything within half a mile and kill an estimated 75,000 to 100,000 people. Another 100,000 to 200,000 would suffer complexed radiation burns, while others would be exposed to high doses of radiation that would cause acute radiation syndrome that is characterized by bone marrow failure and gastrointestinal, cardiac, neurological and pulmonary toxicity. The starkest fact about a nuclear bomb attack is that it destroys the capacity to respond from a medical and civil service perspective. There will be a loss of local government services from firefighters, police and hospitals, along with loss of water, sewage and utilities. There will be a loss of communication systems to direct survivors where to evacuate for treatment.
The management of mass casualties from nuclear detonation is far more complex than for natural disasters. Hot zones are too dangerous for first responders to enter to render medical assistance to casualties. Yet, victims would still need to be evacuated somehow. According to the report, most U.S. cities lack medical preparedness to manage the aftermath of a nuclear explosion. FEMA has not devoted enough attention to address this issue. This makes it important for cities and states to develop plans for the worse case scenarios. Each state should have a plan of preparedness that includes special medical triage centers; coordinated schemes from state military and local police to provide mobile communication assets and protection against civil unrest; and specialized trained hospitals that can medical manage the injuries associated with a nuclear bomb. There needs to be a statewide plan from the governor’s office from each state, along with each state’s department of public health, to ensure there is sufficient medical preparedness.
Several government officials stated they were unable to take steps forward out of being accused of inciting fearmongering. However, developing a comprehensive preparedness program against nuclear threats should not just stop with military action but should include a medical preparation program regardless of how politically undesirable the subject may be. Preparedness should be mandated at every local and state government level.

Annick Girardin has told journalists in Tahiti that there will be an answer to the recently raised calls for such a study.Last week, a child psychiatrist, who had worked in French Polynesia for years, suggested that an independent investigation be carried out after noticing a high incidence of disturbed and deformed children among the off-spring of people exposed to radiation from the atmospheric tests.
Girardin has acknowledged the concerns, saying it has to be established how to deal with the question and to see if it is possible to work on it with other countries.
The minister has restated that the former president Francois Hollande recognised two years ago in Papeete the French legacy and assumed responsibility.
She has also launched a project in Papeete to build an institute of archives and documents related to the tests.
She has also frozen the sale of land in the city previously used by the navy for its command for it to be able to be used for a memorial site.The head of the nuclear test veteran’s organisation Roland Oldham is dismissive, saying this will only see the light of day once people are dead.
He has continued to urge Paris to compensate the nuclear test victims suffering from poor health.
Until 2009, France claimed its weapons tests were clean but then passed a law accepting compensation demands.
Hundreds of applications have been filed since but almost all have been thrown out.
Radiation damage to any cells but the reproductive organs. Genetic damage. Damage to the reproductive cells. Birth defects may result.
Genetic damage from radiation highlights need to protect physicians in cath lab, Cardiovascular Business, Jan 12, 2018 | Daniel AllarA pair of studies published in October added to the growing literature on the harmful effects of radiation exposure to interventional cardiologists in the cath lab.
One study showed brain-specific microRNA (miRNAs) was significantly down regulated in operators exposed to radiation when compared to age- and sex-matched controls who had no occupational exposure. Another found genetic biomarkers for DNA damage/repair rose significantly after procedures that required radiation but then returned to baseline levels after 24 hours. Notably, the use of protective leg shielding mitigated the damage.
Charles E. Chambers, MD, who authored an editorial accompanying the studies in Circulation, spoke to Cardiovascular Business about this research and recent developments that could improve operator safety. Here are three key takeaways from that conversation:
1. These studies were novel because they showed genetic damage related to radiation exposure.
This differs from previous research, Chambers said, which centered on hard clinical outcomes or the development of orthopedic injuries from years spent wearing heavy lead clothing to shield against radiation.
“But now these two studies suggest that radiation is what we were worried about all along. It really does increase genetic alterations,” he said.
Because dysregulated miRNA has been linked to certain forms of epilepsy, Alzheimer’s disease and brain cancers, the study authored by Andrea Borghini and colleagues raises the concern that radiation may also tie into cognitive impairment.
“We’re fortunate, I think, that there aren’t more tumors, there aren’t more long-term ramifications from radiations, but I also wonder—one of the articles mentioned dementia—are we missing subtleties, occupational hazards in people that are chronically exposed to radiation that we’re attributing to aging, but are enhanced by radiation?” Chambers said. “The importance of protecting the patients is always there, but we should not underestimate the importance of protecting the operator and staff.”………
3. Robotic procedures could eventually limit operators’ radiation risk.
Reducing dosage is one way to reduce risk. Two others are increasing the distance from the radiation source and decreasing the time spent near that source.
Robotic technology has the potential to address both concerns.
AWE bids for ‘more realistic’ nuclear terrorism tests licence, The UK’s nuclear warhead factory is bidding for a licence change to run “more realistic” tests in preparation for “nuclear terrorism”.
Hanford radioactive monitoring not protecting workers, By Annette Cary, Tri-City Herald, January 25, 2018 New test results show that monitoring for airborne radioactive contamination has not protected Hanford nuclear reservation workers as the site’s highly contaminated Plutonium Finishing Plant is demolished.
Two more Hanford workers have inhaled or ingested small amounts of airborne radioactive material, with tests for 180 workers still pending, according to the Department of Energy.
The most recent results were for the first 91 workers who requested testing after a spread of radioactive material was discovered in mid-December.
In addition, air samples collected and analyzed at sites outside the demolition zone around the plant show that airborne radioactive contamination was not found in 2017 by other monitoring methods meant to more quickly warn of a potential danger to workers.
A memo with the latest results for both checks for radioactive contamination of workers and for air monitoring results was sent to Hanford workers Wednesday afternoon by Doug Shoop, manager of the DOE Hanford Richland Operations Office.
In one case, airborne contamination that appeared to be linked to demolition of the plant was found about 10 miles away, near the K Reactors along the Columbia River, workers were told. The finding follows an earlier discovery of airborne contamination in June at the Rattlesnake Barricade, a secure entrance to Hanford just off public Highway 240…….. http://www.columbian.com/news/2018/jan/25/hanford-radioactive-monitoring-not-protecting-workers/
Fukushima heroes on both sides of the Pacific still fighting effects of radiation, stress and guilt, Following the catastrophic earthquake and tsunami of 2011, selfless Japanese workers battled nuclear-reactor meltdown, and thousands of US troops provided disaster relief. Today, many are counting the cost to their mental and physical health, SCMP, BY ROB GILHOOLY, 25 JAN 2018 Christmas Day saw dozens of masked men descend on Futaba, in the northeast of Japan’s main island of Honshu. They moved deliberately along deserted streets, clearing triffid-like undergrowth and preparing to demolish derelict buildings. Their arrival marked the beginning of an estimated four-year government-led project to clean up Futaba, which has succumbed to nature since its residents deserted almost seven years ago.
Futaba is one of two towns (the other being neighbouring Okuma) on which sits the 350-hectare Fukushima Daiichi Nuclear Power Plant, which experienced multiple reactor meltdowns and explosions in March 2011, contaminating huge swathes of land and forcing the evacuation of 160,000 residents – all the result of the magnitude-nine undersea Tohoku earthquake and the devastating mega-tsunami that hit on March 11, claiming up to 21,000 lives.
Despite 96 per cent of Futaba still being officially designated as uninhabitable due to high radiation levels, the government has set spring 2022 as the return date for its 6,000 or so residents. That the government has also built a 1,600-hectare facility to store up to 22 million cubic metres of nuclear waste in the town has led to doubts that many will return.
I find it difficult to believe anyone would want to go back,” says Ryuta Idogawa, 33, a former employee at Fukushima Daiichi operator Tokyo Electric Power Co (Tepco), and one of the so-called “Fukushima 50” – a hardcore of station workers who remained on-site after 750 others had been evacuated, battling to bring the melting reactors under control at great risk to their own safety.
“They say time heals,” Idogawa adds, “but that depends how deep the wounds are.”
On the other side of the world, members of a different and larger group of people than the Fukushima 50 are suffering health problems, ostensibly as a result of the disaster. For more than seven weeks following the catastrophe, the United States mounted a massive disaster relief mission, dubbed Operation Tomodachi (the Japanese word means “friend”). The initiative directly or indirectly involved 24,000 US service personnel, 189 aircraft and 24 naval ships, at a total cost US$90 million.
While the mission was lauded a success by the US and Japanese governments, during Operation Tomodachi, thousands of US sailors were inadvertently exposed to a plume of radiation that passed over their ships, which were anchored off the Pacific coast of Japan. Since then, several hundred have developed life-changing illnesses, such as degenerative diseases, tumours and leukaemia, and defects have been detected in foetuses of some pregnant women. All are a result, they claim, of being irradiated by the plume.
According to one report, 24 sailors, who were in their late teens or 20s at the time, are living with a variety of cancers. At least six have died since 2011, while others suffer post-traumatic stress disorder (PTSD).
“Unlike the nuclear plant workers, these sailors had no protective clothing, in fact some of them literally had no shirts on their backs because they had given all their clothing away to people they saved from the tsunami waves,” says Charles Bonner, a lawyer at one of three law offices representing 402 sailors who have filed a US$5 billion lawsuit against Tepco and General Electric Co, a suit that has been given the go-ahead to be heard in a US federal court. (Fukushima Daiichi’s Reactor No. 1 – the plant’s oldest reactor – was built by American manufacturer General Electric Co.)
“And because they had given away all their bottled water to tsunami survivors, they were drinking desalinated water that also had been contaminated,” Bonner continues. “I do not doubt the psychological impact of the disasters on the plant workers, but at least they had masks and protective clothing, as required by law. The sailors, however, knew nothing of their exposure and were literally marinated in the radiation.”……….
lawyer Bonner says that while his team represents more than 400 sailors, there were a further 69,600 American citizens – military and civilian – potentially affected by the radiation, and who have yet to join the class lawsuit.
He also expresses indignation at the Royal Society study and the viewpoint of cancer expert Thomas, insisting that the health of the young US service men and women aboard the ships was endangered and in many cases compromised by Operation Tomodachi. “[The sailors] were certified by the Navy as healthy and fit, so why are they getting cancer and other illnesses?” he asks. “That can only be because they were exposed to radiation. It can’t just be a coincidence.”…….. http://www.scmp.com/magazines/post-magazine/long-reads/article/2130359/fukushima-heroes-both-sides-pacific-still
The finding comes as Nasa continues to prepare for missions to Mars and beyond. By Shubham Sharma, As Nasa continues to prepare for manned deep-space missions to Mars and beyond, a new study has highlighted a major concern for the agency – the affect of long-term space travel on astronauts’ retinal nerves, which ultimately degrades their ability to see.Nearly 50% of astronauts report cases of vision impairment after spending a prolonged time in space, sometimes months or maybe years after returning to Earth. The cases vary from person to person but the new study, published in the journal JAMA Ophthalmology and reported by Live Science, factors something that could be the key trigger for these problems.
After studying pre- and post-flight optical scans of 15 astronauts who had spent around six months in space, researchers noted a significant change in their optic nerves, the delicate transmitter that takes visual information from the retina to the vision centres of the brain, helping a person register what they see.
As per the report, the analysis of Bruch membrane openings, the gaps at the back of the eyeball through which these nerves travel, revealed that their delicate tissues were significantly swollen and warped.
The critical damage was noted weeks after the astronauts’ return to Earth and has been touted as the first direct observational evidence that highlights the critical effect of long-term space travel on optic nerves. Some of the study subjects already had vision-related problems but the patterns in the deformity could not be ignored.
Though the actual cause of this condition remains unknown, the researchers believe it could be due to the difference between normal and cosmic pressures. According to them, when astronauts reach space, the pressure increases and the eyes take their time to adjust to that change. However, when they come back to Earth, the pressure goes down suddenly, which the eyes fail to deal with.
As of now, it cannot be said for certain if this is the exact reason, but whatever it may be, Nasa will have to study this problem carefully before going ahead with its deep-space missions. The success of any manned program, whether to the Moon, Mars or any other distant planet, will depend on astronauts and how they react to changes in their surroundings several thousand kilometres away from Earth.
Even though it’s over 30 years since the 1986 Chernobyl nuclear disaster, radiation levels exceeding 39 706 Bq (becquerel) per kilo have been found in Swedish wild boar meat taken from the Uppland area.
According to the Swedish Radiation Safety Authority, this is the highest ever level measured in wild boar meat in Sweden, way exceeding the 1500 Bq/kg safe limit set by the Swedish Food Agency for meat consumption.
Speaking to The Local, Paul Andersson of the Swedish Radiation Authority explained that “wild boar were practically non-existent outside the southern counties of Skåne and Sörmland, two Swedish counties unaffected by radiation. However, in the years since, the wild boar population has multiplied and migrated to northern areas of Sweden”, which is why the authority is keen to test wild boar meat.
Andersson noted that wild boar may be particularly susceptible to radiation for a number of reasons: ”Wild boar forage for wild mushrooms and have the ability to find truffles in the ground, which may explain why this particular wild hog had such high levels of radiation.”
In contrast, he said elk meat’s radiation levels have consistently gone down since 1986, rarely exceeding the safety limit for meat consumption of 1500 Bq/kg.
The authority is encouraging hunters to send them wild boar meat samples for testing.
