The News That Matters about the Nuclear Industry Fukushima Chernobyl Mayak Three Mile Island Atomic Testing Radiation Isotope

Algeria: deep resentment of French colonialism and the effects of nuclear bombing -still very real today.

In Algeria, France’s 1960s nuclear tests still taint ties,   https://www.france24.com/en/africa/20210729-in-algeria-france-s-1960s-nuclear-tests-still-taint-ties   More than 60 years since France started its nuclear tests in Algeria, their legacy continues to poison relations between the North African nation and its former colonial ruler.The issue has come to the fore again after President Emmanuel Macron said in French Polynesia on Tuesday that Paris owed “a debt” to the South Pacific territory over atomic tests there between 1966 and 1996.

The damage the mega-blasts did to people and nature in the former colonies remains a source of deep resentment, seen as proof of discriminatory colonial attitudes and disregard for local lives.

Diseases related to radioactivity are passed on as an inheritance, generation after generation,” said Abderahmane Toumi, head of the Algerian victims’ support group El Gheith El Kadem.

“As long as the region is polluted, the danger will persist,” he said, citing severe health impacts from birth defects and cancers to miscarriages and sterility.
France carried out its first successful atomic bomb test deep in the Algerian Sahara in 1960, making it the world’s fourth nuclear power after the United States, the Soviet Union and Britain.

Today, as Algeria and France struggle to deal with their painful shared history, the identification and decontamination of radioactive sites remains one of the main disputes.

In his landmark report on French colonial rule and the 1954-62 Algerian War, historian Benjamin Stora recommended continued joint work that looks into “the locations of nuclear tests in Algeria and their consequences”.

France in the 1960s had a policy of burying all radioactive waste from the Algerian bomb tests in the desert sands, and for decades declined to reveal their locations.

‘Radioactive fallout’

Algeria’s former veterans affairs minister Tayeb Zitouni recently accused France of refusing to release topographical maps that would identify “burial sites of polluting, radioactive or chemical waste not discovered to date”.”The French side has not technically conducted any initiative to clean up the sites, and France has not undertaken any humanitarian act to compensate the victims,” said Zitouni. According to the Ministry of the Armed Forces in Paris, Algeria and France now “deal with the whole subject at the highest level of state”.

“France has provided the Algerian authorities with the maps it has,” said the ministry.

Between 1960 and 1966, France conducted 17 atmospheric or underground nuclear tests near the town of Reggane, 1,200 kilometres (750 miles) from the capital Algiers, and in mountain tunnels at a site then called In Ekker.

Eleven of them were conducted after the 1962 Evian Accords, which granted Algeria independence but included an article allowing France to use the sites until 1967.

A radioactive cloud from a 1962 test sickened at least 30,000 Algerians, the country’s official APS news agency estimated in 2012.
French documents declassified in 2013 revealed significant radioactive fallout from West Africa to southern Europe. Algeria last month set up a national agency for the rehabilitation of former French nuclear test sites.

In April, Algeria’s army chief of staff, General Said Chengriha, asked his then French counterpart, General Francois Lecointre, for his support, including access to all the maps.

We respect our dead’Receiving the maps is “a right that the Algerian state strongly demands, without forgetting the question of compensation for the Algerian victims of the tests,” stressed a senior army officer, General Bouzid Boufrioua, writing in the defence ministry magazine El Djeich.”France must assume its historical responsibilities,” he argued.President Abdelmadjid Tebboune, however, ruled out any demands for compensation, telling Le Point weekly that “we respect our dead so much that financial compensation would be a belittlement. We are not a begging people.”France passed a law in 2010 which provided for a compensation procedure for “people suffering from illnesses resulting from exposure to radiation from nuclear tests carried out in the Algerian Sahara and in Polynesia between 1960 and 1998”.

But out of 50 Algerians who have since launched claims, only one, a soldier from Algiers who was stationed at one of the sites, “has been able to obtain compensation”, says the International Campaign to Abolish Nuclear Weapons (ICAN).

No resident of the remote desert region has been compensated, it said.

In a study released a year ago, “Radioactivity Under the Sand”, ICAN France urged Paris to hand Algeria a complete list of the burial sites and to facilitate their clean-up.

The 2017 Treaty on the Prohibition of Nuclear Weapons obliges states to provide adequate assistance to individuals affected by the use or testing of nuclear weapons.

It was signed by 122 UN member states, but by none of the nuclear powers. France argued the treaty was”incompatible with a realistic and progressive approach to nuclear disarmament”.

ICAN France in its study argued that “people have been waiting for more than 50 years. There is a need to go faster.

“We are still facing an important health and environmental problem that must be addressed as soon as possible.”

The need for integrity in epidemiological research: investigation of uranium miners’health to be carried out by pro nuclear bodies

“They want to show that it doesn’t cause cancer. I think they want to find that result.”

for years, the CNSC has served both as a regulator and promoter of the nuclear industry

“It is concerning that health standards are set by physicists and industries, based on financial and technological convenience, rather than by those educated in and committed to public health and safety.”


Canadian Nuclear Safety Commission to Investigate Lung Cancer Rates Among Uranium Workers, Mother Jones

What’s happened to 80,000 people who have worked in Canada’s mines and processing facilities?CHARLES MANDEL, 25 July 21, The Canadian Nuclear Safety Commission (CNSC) is leading a national study examining incidences of lung cancer in uranium workers from across the country.

The Canadian Uranium Workers Study (CANUWS) will examine health data from 80,000 past and present employees at Canada’s uranium mines, mills and processing and fabrication facilities. The study, which is now underway and set to end in 2023, is the largest examination of lung cancer in Canadian uranium workers to date.

Rachel Lane, one of the lead researchers on the new study, told Canada’s National Observer she believes it will reassure workers they face less risk than before from lung cancer arising from exposure to radon, ……..

The $800-million mining and milling uranium industry employs over 2,000 people—of whom more than half are residents of northern Saskatchewan—at mine sites. The researchers plan to examine causes of death in uranium workers from 1950 on and chart their cancer data from 1970 onwards, using research from previous studies.

The new study will build on the results of two historical studies: the Eldorado study and the Ontario Uranium Mine Workers Study, both of which found elevated risks of lung cancer in uranium workers. During numerous follow-ups ending in 2015, both studies found lung cancer among miners was still more prevalent than in the general population………….

deaths from lung cancer associated with radiation were historically higher for uranium workers than the general male population……….

In 2015, a follow-up to the 2007 Ontario Uranium Miner Cohort study was done. It examined approximately 28,546 male and 413 female uranium miners who had worked at least one week in the Elliot Lake and Bancroft regions or at the Agnew Lake Mine between 1954 and 1996.

The conclusion: “Significant elevations in lung cancer mortality and incidence, as well as silicosis and injury mortality were observed in comparison with the general Canadian population.”……….

Anne Leis, the department head of Community Health and Epidemiology at the University of Saskatchewan, will administer the project and analyze the data. Her colleague, Punam Pahwa, a professor of biostatistics, will lead the statistical analysis of the health data……….

Uranium mining companies Cameco, Orano, and BWXT are co-funding the study, contributing $60,000. The CNSC is providing $125,000, while the Saskatchewan government is kicking in $60,000, and the University of Saskatchewan is contributing $90,000 of in-kind funding.………… 

Concerns Over Possible Bias

While former employees and industry watchers applaud efforts to study the health of uranium workers, some are skeptical about the ability of CNSC to produce an unbiased report.

Jamie Kneen, communications and outreach coordinator at Mining Watch Canada, says it’s important to understand the longer-term impacts of radon on the miners. But he cautions that the peer review and oversight of the study must be carefully examined because it is being led by CNSC.Kneen contends that for years, the CNSC has served both as a regulator and promoter of the nuclear industry. “Their tendency has been to extend license periods and to give operators, whether it’s in the uranium industry or the nuclear power industry, more space, more time in terms of licensing and more leeway rather than the kind of tight supervision and oversight that the public probably would expect.”

Therefore, it’s a question of scrutinizing who’s doing the work and reviewing the study to ensure that it really is independent, according to Kneen. He notes that’s a difficult task given that the methodology around radiation is intricate and that not many people can decipher the technical details.

“So there’s a lot of potential for not necessarily deliberate manipulation, but for error to creep in and biases to creep in.”

Rod Gardiner, a former general foreman at the now-defunct Cluff Lake Mine in Saskatchewan, expresses his own concerns about the industry. Gardiner was at the mine for 33 years, working his way up to general foreman and acting mine manager.

He alleges management at Cluff Lake, which was owned by the multinational mining corporation Orano Group, consistently boasted that working in the mine was as safe as working in a supermarket and putting prices on soup cans. “That’s what they used to say, the company.”

He hopes a new study might answer questions about workers’ health. But others aren’t sure whether results will be trustworthy, primarily because the CNSC is partially funding and leading the study.

The CNSC’s work has been subject to just those kinds of complaints in the past.

Writing in the journal Canadian Family Physician in 2013, Dale Dewar and two other authors expressed concern over the CNSC’s ability to act independently of government and industry. The authors noted the former Conservative federal government fired the commission’s CEO when she applied safety guidelines to shut down the Chalk River reactor in Ontario.

The authors observed: “It is concerning that health standards are set by physicists and industries, based on financial and technological convenience, rather than by those educated in and committed to public health and safety.”

Dewar, a longtime general physician in northern Saskatchewan, recently told Canada’s National Observer: “They want to show that it doesn’t cause cancer. I think they want to find that result.”

Dewar expressed surprise that the CNSC has opted for a focused study when northerners have been asking for decades for a baseline health study to determine such things as whether or not there have been increases in autoimmune diseases or cancers that couldn’t be explained by diet, for example.

“I think not only is it virtually a sin that they’ve never done this, but I think it’s a really huge missed opportunity because if they had a study done like this, they would have researchers around the world trying to get information out of it.”…………

Compensation for Uranium Workers

Another, less discussed issue is compensation for uranium miners. In the United States, the Radiation Exposure Compensation Act (RECA) administered by the Department of Justice has awarded over US$2.4 billion in benefits to more than 37,000 claimants since its introduction in 1990. https://www.motherjones.com/environment/2021/07/canadian-nuclear-safety-commission-to-investigate-lung-cancer-rates-among-uranium-workers/

Most Hanford nuclear site workers report exposure to toxic or radioactive chemicals


57% of Hanford nuclear site workers surveyed by WA state report toxic exposures, Tri City Herald

BY ANNETTE CARY, JULY 07, 2021 

 More than half of Hanford site workers responding to a Washington state survey said they had been involved in an incident at the Hanford nuclear reservation that resulted in exposure to radioactive or toxic chemicals.

Some 57% of about 1,600 past and present workers who took the survey reported being in an exposure incident, which could include the release of radioactive material into the air.

And nearly a third, 32%, reported they had long-term exposure to hazardous materials at the nuclear reservation, rather than exposure during a single incident………

Workers are cleaning up and treating radioactive and hazardous chemical waste left from the past production at Hanford of two-thirds of the nation’s plutonium for its nuclear weapons program……….

For incurable diseases, such as chronic beryllium disease caused by breathing in fine particles of the metal beryllium, information sharing could be key to finding cures, the board said.

SICK HANFORD WORKER ISSUES

It also recommended expanding Tri-Cities access to care that is tailored to Hanford workers’ health needs.

Some workers reported they did not receive a diagnosis until they visited clinics outside the Tri-Cities area and sometimes outside the state.

After an initial assessment or diagnosis related to Hanford exposures there was not long-term coordination of care, said workers in survey comments.

Part of the difficulty was that some health problems, such as cancers, are not diagnosed until years after exposures, the report said……………https://www.tri-cityherald.com/news/local/hanford/article252613523.html

Perils to austronauts’ health – high radiation and low gravity

High Radiation, Low Gravitation: The Perils of a Trip to Mars, Sunscreen and calcium supplements aren’t enough to protect Mars-bound space travelers from radiation and a lack of gravity in outer space.   July 23, 2021 – 17:00Yuen Yiu, Staff Writer   (Inside Science) — Back in May, SpaceX launched its Starship SN15 prototype to about the cruising altitude of a commercial airliner before landing it safely. The company claims future versions of the rocket will be able to take 100 passengers at a time to the moon, and even Mars.  

But while it’s one thing to send a rocket to Mars, it’s another to send people there alive. And it’s yet another thing to make sure the people can be as healthy as they were when they left Earth. 

Besides packing enough fuel and air and water and food for the seven-month-long journey to Mars (and more for a return trip if you want a return ticket), there are other luxuries we enjoy here on Earth that the spaceship will have to provide if we want to stay healthy during the long flight. 

Nasty sunburns and zero gravity

Earth’s atmosphere and magnetic field protect us from harmful space radiation, but passengers bound for Mars will lose that protection. So, their spaceship would need to provide some kind of radiation shielding.

Depending on where radiation comes from, it may be made of different particles and have different energies, which would require different means of shielding and pose different levels of danger to our radiation-prone DNA. For example, radiations from energetic particles ejected from the sun behave very differently than cosmic rays from outside our galaxy. 

So, how many times more radiation would a Mars-bound astronaut experience compared to what they would experience on Earth? 

Enough to be of concern, according to Athanasios Petridis, a physicist from Drake University in Des Moines. According to calculations by his team, high-end estimates for radiation exposure during a round trip to Mars are in the range of several Sieverts (Sv). For reference, the U.S. Nuclear Regulatory Commission has set 0.05 Sv/year as the dose limit for workers who are exposed to radiation at their jobs.

Solar weather also plays a role in the amount of radiation you would get in space. For instance, the 11-year solar cycle affects the amount of radiation the sun emits. However, due to the complicated interplay between sun-generated radiation and cosmic rays from outer space, it may not be worth it to time the launch around these cycles. 

“There are enough competing factors in radiation exposure that trying to plan around the solar cycle is like trying to time the stock market, which usually results in losing,” said Kerry Lee, a radiation analyst from NASA in Houston, Texas.

The lack of gravity can also wreak havoc on the human body given enough time. Astronauts aboard space stations have been shown to lose 1 to 1.5 % of the mineral density in their weight-bearing bones every month. They also tend to lose muscle mass, even when exercising as much as they do on Earth. ………..  https://www.insidescience.org/news/high-radiation-low-gravitation-perils-trip-mars

Environment Working Group recommends stringent health-based standards for radiation exposure from wireless devices 

EWG study recommends stringent health-based standards for radiation exposure from wireless devices  Medical Network  News, 21 July 21, A peer-reviewed study by the Environmental Working Group recommends stringent health-based exposure standards for both children and adults for radiofrequency radiation emitted from wireless devices. EWG’s children’s guideline is the first of its kind and fills a gap left by federal regulators.

The study, published in the journal Environmental Health, relies on the methodology developed by the Environmental Protection Agency to assess human health risks arising from toxic chemical exposures. EWG scientists have applied the same methods to radiofrequency radiation from wireless devices, including cellphones and tablets.

EWG recommends the Federal Communications Commission, or FCC, adjust its woefully outdated health standards for wireless radiation, last revised a quarter-century ago, well before wireless devices became ubiquitous, heavily used appliances synonymous with modern life. The recommendation draws on data from a landmark 2018 study from the National Toxicology Program, or NTP, one of the largest long-term studies on the health effects of radiofrequency radiation exposure.

EWG’s new guidelines, the first developed in the U.S. to focus on children’s health, recommend that children’s exposure overall be 200 to 400 lower than the whole-body exposure limit set by the FCC in 1996.

The EWG recommended limit for so-called whole-body Specific Absorption Rate, or SAR, for children is 0.2 to 0.4 milliwatts per kilogram, or mW/kg. For adults, EWG recommends a whole-body SAR limit of 2 to 4 mW/kg, which is 20 to 40 times lower than the federal limit.

The FCC has not set a separate standard for children. Its standards for radiofrequency radiation set a maximum SAR of 0.08 watts per kilogram, or W/kg, for whole-body exposure and an SAR for localized spatial peak – the highest exposure level for a specific part of the body, such as the brain – of 1.6 W/kg for the general population.

The NTP studies examined the health effects of 2G and 3G wireless radiation and found there is “clear evidence” of a link between exposure to radiofrequency radiation and heart tumors in laboratory animals. Similar results were reported by a team of Italian scientists from the Ramazzini Institute.

Cellphone radiation was classified a “possible carcinogen” in 2011 by the International Agency for Research on Cancer, part of the World Health Organization, a conclusion based on human epidemiological studies that found an increased risk of glioma, a malignant brain cancer, associated with cellphone use.

EWG scientists say that more research is needed on the health impacts of the latest generation of communication technologies, such as 5G. In the meantime, EWG’s recommendation for strict, lower exposure limits for all radiofrequency sources, especially for children………

“We have grave concerns over the outdated approach the federal government has relied on to study the health effects of cellphone radiation and set its current safety limit and advice for consumers,” said EWG President Ken Cook. “Government guidelines are a quarter-century old and were established at a time when wireless devices were not a constant feature of the lives of nearly every American, including children.”…………

“The evidence shows that children absorb more radiofrequency radiation than adults, and the developing body of a child is more vulnerable to such effects,” said Olga Naidenko, Ph.D., EWG’s vice president for science investigations and co-author of the study.

“More research on the safety and sustainability of wireless technology is essential,” added Naidenko. “Meanwhile, there are simple steps everyone can take to protect their health, such as keeping wireless devices farther from their bodies.”……

EWG’s recommendation for limits for radiofrequency radiation exposure is its latest effort to advance the public dialogue about science-based standards that protect public health.  https://www.news-medical.net/news/20210720/EWG-study-recommends-stringent-health-based-standards-for-radiation-exposure-from-wireless-devices.aspx

Using snakes to monitor Fukushima radiation,

Using snakes to monitor Fukushima radiation, EurekAlert, 21 July 21,

Researchers placed tiny GPS trackers on rat snakes to track their movements at Fukushima

UNIVERSITY OF GEORGIA  Ten years after one of the largest nuclear accidents in history spewed radioactive contamination over the landscape in Fukushima, Japan, a University of Georgia study has shown that radioactive contamination in the Fukushima Exclusion Zone can be measured through its resident snakes.

The team’s findings, published in the recent journal of Ichthyology & Herpetology, report that rat snakes are an effective bioindicator of residual radioactivity. Like canaries in a coal mine, bioindicators are organisms that can signal an ecosystem’s health.

An abundant species in Japan, rat snakes travel short distances and can accumulate high levels of radionuclides. According to the researchers, the snakes’ limited movement and close contact with contaminated soil are key factors in their ability to reflect the varying levels of contamination in the zone.

Hanna Gerke, an alumna of UGA’s Savannah River Ecology Laboratory and the Warnell School of Forestry and Natural Resources, said tracked snakes moved an average of just 65 meters (approximately 213 feet) per day.

An abundant species in Japan, rat snakes travel short distances and can accumulate high levels of radionuclides. According to the researchers, the snakes’ limited movement and close contact with contaminated soil are key factors in their ability to reflect the varying levels of contamination in the zone.

Our results indicate that animal behavior has a large impact on radiation exposure and contaminant accumulation,” Gerke said. “Studying how specific animals use contaminated landscapes helps increase our understanding of the environmental impacts of huge nuclear accidents such as Fukushima and Chernobyl.”  https://www.eurekalert.org/pub_releases/2021-07/uog-ust072021.php

Astronauts to Mars – a game of cancer-russian-roulette, especially dangerous to women

women were more likely to develop lung cancer than men, suggesting a greater sex-based vulnerability to harmful radiation.

the risk to an astronaut exposed to space radiation is long-term rather than immediate. Without proper shielding (which tends to be rather heavy and thus prohibitively expensive to launch) their chances of developing cancer, as well as cardiovascular disease, cataracts and central nervous system damage, slightly increase each day they are in space. In a person’s cells, space radiation can sever both strands of a DNA molecule’s double helix. And while a few such instances might come with very limited risks, each additional severance raises the odds of developing a harmful mutation that could cause cancer………

New Space Radiation Limits Needed for NASA Astronauts, Report Says, Scientific American, By Ramin Skibba on July 14, 2021 https://www.scientificamerican.com/article/new-space-radiation-limits-needed-for-nasa-astronauts-report-says/   Although meant to minimize risks to human health, the proposed new limits would still be exceeded by any conceivable near-future crewed voyage to MarsAstronaut Scott Kelly famously spent an entire year residing onboard the International Space Station (ISS), about 400 kilometers above Earth, and his NASA colleague Christina Koch spent nearly that long “on station.” Each returned to Earth with slightly atrophied muscles and other deleterious physiological effects from their extended stay in near-zero gravity.

But another, more insidious danger lurks for spacefarers, especially those who venture beyond low-Earth orbit.

Space is filled with invisible yet harmful radiation, most of it sourced from energetic particles ejected by the sun or from cosmic rays created in extreme astrophysical events across the universe. Such radiation can damage an organism’s DNA and other delicate cellular machinery. And the damage increases in proportion to exposure, which is drastically higher beyond the protective cocoon of Earth’s atmosphere and magnetic field (such as on notional voyages to the moon or Mars). Over time, the accrued cellular damage significantly raises the risk of developing cancer.

To address the situation, at NASA’s request, a team of top scientists organized by the National Academies of Sciences, Engineering, and Medicine published a report in June recommending that the space agency adopt a maximum career-long limit of 600 millisieverts for the space radiation astronauts can receive. The sievert is a unit that measures the amount of radiation absorbed by a person—while accounting for the type of radiation and its impact on particular organs and tissues in the body—and is equivalent to one joule of energy per kilogram of mass. Scientists typically use the smaller (but still quite significant) quantity of the millisievert, or 0.001 sievert. Bananas, for instance, host minute quantities of naturally occurring radioactive isotopes, but to ingest a millisievert’s worth, one would have to eat 10,000 bananas within a couple of hours.

Every current member of NASA’s astronaut corps has received less than 600 millisieverts during their orbital sojourns, and most, including Koch, have received much less and can thus safely return to space. But a year on the ISS still exposes them to more radiation than experienced by residents of Japan who lived near the Fukushima Daiichi nuclear accidents of 2011.

“Everybody is planning trips to the moon and Mars,” and these missions could have high radiation exposures, says Hedvig Hricak, lead author of the report and a radiologist at Memorial Sloan Kettering Cancer Center in New York City. Using current spaceflight-proved technologies, long-distance voyages—especially to the Red Planet—would exceed the proposed threshold, she says.

That could be a big problem for NASA’s Artemis program, which seeks to send astronauts to the moon in preparation for future trips to Mars. Another problem for the space agency is that the epidemiological data it uses mostly come from a longevity study of Japanese survivors of atomic bomb blasts, as well as from the handful of astronauts and cosmonauts who have endured many months or even years in low-Earth orbit. NASA’s current space radiation limit, which was developed in 2014, involves a complicated risk assessment for cancer mortality that depends on age and sex, yet more relevant data are necessary, Hricak argues. In the atomic bomb survivor study, for instance, women were more likely to develop lung cancer than men, suggesting a greater sex-based vulnerability to harmful radiation. “But with the knowledge we presently have, we know we cannot make a comparison between high exposure versus chronic exposure,” Hricak says. “The environment is different. There are so many factors that are different.”

NASA wants to update its standards now because the agency is on the cusp of sending so many astronauts well beyond low-Earth orbit, where greater amounts of space radiation seem destined to exceed previously mandated exposure limits. Furthermore, Hricak says, having a single, universal radiation limit for all space travelers is operationally advantageous because of its simplicity. A universal limit could also be seen as a boon for female astronauts, [ Ed. a boon?when they still are more susceptible to cancer than men are?] who had a lower limit than men in the old system and therefore were barred from spending as many days in space as their male counterparts.

The new radiation limit proposed by Hricak and her team is linked to the risks to all organs of a 35-year-old woman—a demographic deemed most vulnerable in light of gender differences in the atomic bomb survivor data and the fact that younger people have higher radiation risks, partly because they have more time for cancers to develop. The goal of the radiation maximum is to keep an individual below a 3 percent risk of cancer mortality: in other words, with this radiation limit, at most three out of 100 astronauts would be expected to die of radiation-induced cancer in their lifetime.

“NASA uses standards to set spaceflight exposure limits to protect NASA astronauts’ health and performance, both in mission and after mission,” says Dave Francisco of NASA’s Office of the Chief Health and Medical Officer. He acknowledges that, while astronauts on Mars missions would benefit from the thin Martian atmosphere that provides some limited protection, “transit in deep space has the highest exposure levels.”

That means long-haul space trips come with the biggest risks. A stay on the lunar surface for six months or more—presuming, of course, that astronauts eventually have a presence there and do not spend most of their time in subsurface habitats—would involve nearly 200 millisieverts of exposure, a higher amount than an extended visit to the ISS. And an astronaut traveling to Mars would be exposed to even more radiation. Whether they reached the Red Planet through a lunar stopover or on a direct spaceflight, they could have experienced significant radiation exposure en route. Even before they embarked on the trip back home, they could have already exceeded the 600 millisievert limit. The entire voyage, which would likely last a couple of years, could involve well more than 1,000 millisieverts. So if astronauts—and not just robots—will be sent to Mars, NASA likely will need to request waivers for them,

Hricak says, although the exact process for obtaining a waiver has not yet been laid out.

The report’s proposal for a new radiation maximum is not without its critics. “For a mission to Mars, a 35-year-old woman right at that limit could have an over 10 percent chance of dying in 15 to 20 years. To me, this is like playing Russian roulette with the crew,” says Francis Cucinotta, a physicist at the University of Nevada, Las Vegas, and former radiation health officer at NASA. Despite the supposed benefits the new limits would have for female astronauts, he is concerned that the risks are particularly pronounced for younger women in space.

On the contrary, Hricak says, in its request for new limits, NASA has sought to be conservative. The European, Canadian, and Russian space agencies all currently have a higher maximum allowed dose of 1,000 millisieverts, while Japan’s limit is age- and sex-dependent like NASA’s current one, mainly because of a shared dependence on the atomic bomb survivor data.

But unlike someone in the vicinity of a nuclear explosion, the risk to an astronaut exposed to space radiation is long-term rather than immediate. Without proper shielding (which tends to be rather heavy and thus prohibitively expensive to launch) their chances of developing cancer, as well as cardiovascular disease, cataracts and central nervous system damage, slightly increase each day they are in space. In a person’s cells, space radiation can sever both strands of a DNA molecule’s double helix. And while a few such instances might come with very limited risks, each additional severance raises the odds of developing a harmful mutation that could cause cancer………

considering how little is known about various health risks from different kinds of space radiation, compared with radiation we are familiar with on Earth, researchers will surely continue with more studies like these to protect astronauts as much as possible. “I can tell you exactly how much exposure you’re going to get from a CT scan,” Hricak says, “but there are many uncertainties with space radiation.”….. https://www.scientificamerican.com/article/new-space-radiation-limits-needed-for-nasa-astronauts-report-says/

Most Hanford nuclear cleanup workers exposed to hazardous materials: Washington state report

Most Hanford cleanup workers exposed to hazardous materials: Washington state report  https://thehill.com/policy/energy-environment/561893-most-hanford-workers-exposed-to-hazardous-materials-state-report

BY CELINE CASTRONUOVO – 07/07/21 More than half of all current and former workers involved in the Hanford Nuclear Reservation cleanup effort have said they were exposed to hazardous materials, according to a new report from the Washington state government.

The report, the last in a series from the Department of Commerce’s Hanford Healthy Energy Workers Board, found that 57 percent “of all current and former workers reported being in an exposure event,” with 32 percent saying they experienced “long-term exposure to hazardous materials.”

The 106-page document cited “deep concerns” among current and former workers about “compensation system processes and the healthcare system’s ability to meet workers’ needs,” and identified “deficiencies in continued engagement with workers after an initial assessment or diagnosis as a common obstacle for the Hanford workforce.”

The findings cap eight months of research by a state-commissioned board tasked with making recommendations on addressing the health needs of workers at the Hanford nuclear site.

The 560-square-mile area in Washington was used by the federal government from 1944 to 1987 to produce plutonium for nuclear weapons and missile warheads.

However, the state board noted that during this time, “many highly radioactive byproducts and waste chemicals were dumped directly into the ground or stored in subterranean multi-million-gallon underground storage areas known as tank farms.”

The Department of Energy’s mission at the site shifted from production to cleanup beginning in the late 1980s.

The site has come under increased scrutiny in recent years for its affect on health and the environment, with the Energy Department warning in April that it believed an underground tank at the facility was leaking waste produced by plutonium production.

The Hanford area is considered the most contaminated site of radioactive waste in the U.S.

The board’s final report on Wednesday offered a look at some of the long-term impacts of nuclear production and waste at the site, including incurable conditions like chronic beryllium disease, which leads to scarring of lung tissue.

The board said that “information sharing could be key to finding cures” to the disease and other chronic conditions developed from exposure to hazardous materials.

Other recommendations included the creation of a Hanford Healthy Energy Workers Center to “serve as a centralized clearinghouse for Hanford-specific health-related information that includes up-to-date scientific knowledge, research on emergent topics, exposure data analysis, medical surveillance data analysis and coordinated intergovernmental efforts for policy and advocacy.”

The board said greater access should be given to specialty and follow-up care, and urged health officials to improve “the quality of care available to Hanford workers both at the Hanford site and in the Tri-Cities area.”

Fukushima’s ”nuclear recovery Olympics” has gone even more wrong, as spectators banned.

Fukushima to ban Olympic spectators as Covid cases rise, 
U-turn deals blow to Japan’s hopes of using Games to showcase recovery from 2011 tsunami, Guardian, 10 Jul 21, 
, The Fukushima prefecture of Japan will bar spectators from the Olympic events it hosts this summer owing to rising Covid-19 infections, its governor said on Saturday, reversing a position announced two days earlier by organisers.

The decision deals another blow to Japan’s hopes of using the Olympics to showcase its recovery from a devastating earthquake and tsunami that hit the northern coast in 2011, destroying a nuclear power station in Fukushima in the worst nuclear accident since Chernobyl.

Organisers had said on Thursday there would be no spectators in the host city, Tokyo, as a resurgent coronavirus forced the prime minister, Yoshihide Suga, to declare a state of emergency in the capital that will run throughout the Games, which were already postponed by a year due to the pandemic……..

Fukushima’s move comes a day after the Australian Olympic Committee president, John Coates, expressed optimism about audiences in Fukushima. Japan take on Australia in a softball game that will be the first competition of the Olympics on 21 July, two days before the opening ceremony.

………. Organisers said there was no change to plans for limited crowds in Miyagi, Shizuoka and Ibaraki prefectures.  https://www.theguardian.com/sport/2021/jul/10/fukushima-to-ban-olympic-spectators-as-covid-cases-rise

Mobile phones/cellphones – the health danger from electromagnetic radiation

Ed. note. We know that ionising radiation from nuclear activities causes cancer and other health ill-effects. But we should also be aware of non-ionising radiation, and its effects on health – electromagnetic radiation as emitted by mobile pnones.

Since then, he said, research has shown significant adverse biologic and health effects — including brain cancer — associated with the use of cellphones and other wireless devices. And now, he said, with the fifth generation of cellular technology, known as 5G, there is an even bigger reason for concern.

Moskowitz: Cellphone radiation is harmful, but few want to believe it. Berkely News,  Anne Brice, Berkeley News| JULY 1, 2021 For more than a decade, Joel Moskowitz, a researcher in the School of Public Health at UC Berkeley and director of Berkeley’s Center for Family and Community Health, has been on a quest to prove that radiation from cellphones is unsafe. But, he said, most people don’t want to hear it.

“People are addicted to their smartphones,” said Moskowitz. “We use them for everything now, and, in many ways, we need them to function in our daily lives. I think the idea that they’re potentially harming our health is too much for some people.”

Since cellphones first came onto the market in 1983, they have gone from clunky devices with bad reception to today’s sleek, multifunction smartphones. And although cellphones are now used by nearly all American adults, considerable research suggests that long-term use poses health risks from the radiation they emit, said Moskowitz.

“Cellphones, cell towers and other wireless devices are regulated by most governments,” said Moskowitz. “Our government, however, stopped funding research on the health effects of radiofrequency radiation in the 1990s.”

Since then, he said, research has shown significant adverse biologic and health effects — including brain cancer — associated with the use of cellphones and other wireless devices. And now, he said, with the fifth generation of cellular technology, known as 5G, there is an even bigger reason for concern.

Berkeley News spoke with Moskowitz about the health risks of cellphone radiation, why the topic is so controversial and what we can expect with the rollout of 5G.

Berkeley News: I think we should address upfront is how controversial this research is. Some scientists have said that these findings are without basis and that there isn’t enough evidence that cellphone radiation is harmful to our health. How do you respond to that?

Joel Moskowitz: Well, first of all, few scientists in this country can speak knowledgeably about the health effects of wireless technology. So, I’m not surprised that people are skeptical, but that doesn’t mean the findings aren’t valid.

A big reason there isn’t more research about the health risks of radiofrequency radiation exposure is because the U.S. government stopped funding this research in the 1990s, with the exception of a $30 million rodent study published in 2018 by the National Institute of Environmental Health Sciences’ National Toxicology Program, which found “clear evidence” of carcinogenicity from cellphone radiation.

In 1996, the Federal Communications Commission, or FCC, adopted exposure guidelines that limited the intensity of exposure to radiofrequency radiation. These guidelines were designed to prevent significant heating of tissue from short-term exposure to radiofrequency radiation, not to protect us from the effects of long-term exposure to low levels of modulated, or pulsed, radiofrequency radiation, which is produced by cellphones, cordless phones and other wireless devices, including Wi-Fi. Yet, the preponderance of research published since 1990 finds adverse biologic and health effects from long-term exposure to radiofrequency radiation, including DNA damage.

More than 250 scientists, who have published over 2,000 papers and letters in professional journals on the biologic and health effects of non-ionizing electromagnetic fields produced by wireless devices, including cellphones, have signed the International EMF Scientist Appeal, which calls for health warnings and stronger exposure limits. So, there are many scientists who agree that this radiation is harmful to our health.

Our 2009 review, published in the Journal of Clinical Oncology, found that heavy cellphone use was associated with increased brain cancer incidence, especially in studies that used higher quality methods and studies that had no telecommunications industry funding.

Last year, we updated our review, published in the International Journal of Environmental Research and Public Health, based on a meta-analysis of 46 case-control studies — twice as many studies as we used for our 2009 review — and obtained similar findings Our main takeaway from the current review is that approximately 1,000 hours of lifetime cellphone use, or about 17 minutes per day over a 10-year period, is associated with a statistically significant 60% increase in brain cancer.

Why did the government stop funding this kind of research?

The telecommunications industry has almost complete control of the FCC, according to Captured Agency, a monograph written by journalist Norm Alster during his 2014-15 fellowship at Harvard University’s Center for Ethics. There’s a revolving door between the membership of the FCC and high-level people within the telecom industry that’s been going on for a couple of decades now.

The industry spends about $100 million a year lobbying Congress. The CTIA, which is the major telecom lobbying group, spends $12.5 million per year on 70 lobbyists. According to one of their spokespersons, lobbyists meet roughly 500 times a year with the FCC to lobby on various issues. The industry as a whole spends $132 million a year on lobbying and provides $18 million in political contributions to members of Congress and others at the federal level.

……… there are strong parallels between what the telecom industry has done and what the tobacco industry has done, in terms of marketing and controlling messaging to the public. ………  For safety tips on how to reduce exposure to wireless radiation from the California Department of Public Health and other organizations, Moskowitz recommends readers visit his website, saferemr.com, Physicians for Safe Technology and the Environmental Health Trust.  https://news.berkeley.edu/2021/07/01/health-risks-of-cell-phone-radiation/#:~:text=Moskowitz%3A%20Cellphone%20radiation%20is%20harmful%2C%20but%20few%20want%20to%20believe%20it,-By%20Anne%20Brice&text=For%20more%20than%20a%20decade,radiation%20from%20cellphones%20is%20unsafe.

Epidemiology – an important guide to the pandemic – why not to nuclear radiation-caused disease? -theme for July 2021

Epidemiology – a forgotten science?   But now, in the time of pandemic, it has come into its own.

The coronavirus illness is a global phenomenon. Epidemiologists, formerly just boring old farts, in a world that reveres high tech and space scientists, now are called upon for guidance .

Epidemiologists are not industry’s favourite people. Sir Richard Doll, in the 1950s, combined laboratory studies on mice with painstaking epidemiological research, proving that cigarette smoking causes cancer,  British Tobacco  did not like him.

The nuclear industry learned  – to downgrade epidemiological research, and prevent it wherever possible.  Subservient governments complied with the nuclear industry.

BUT – there has been epidemiological research applied to nuclear’s ionising radiation and its effect on health – just a few examples –  on nuclear workers’ health., on residents of Belarus and Ukraine, on the developing foetus,

Right now, the world sees value in identifying cases, clusters – where the invisible coronavirus exists, with its threat of immediate illness and death.

Equally dangerous  the cases and clusters of accumulating radioactive particles lead to the threat of later illness and death.

It is time that epidemiological research on ionising radiation was done, properly, thoroughly, like Richard Doll’s cigarette study. Time to no longer allow the nuclear industry to downplay and stifle such research, (and not to let them rely on  their own biased studies)

Japan is not being transparent about the radioactive content in Fukushima wastewater


A 2018 TEPCO report revealed that even after filtration the treated water still contained other radionuclides, such as strontium-90 and iodine-129, above regulatory-limit levels.

Japan’s nuclear wastewater plan is clouded by politics
29 June 2021  East Asia Forum Author: Yasuo Takao, Curtin University

The Japanese government’s approval of a plan to discharge treated radioactive water stored at the Fukushima Daiichi nuclear plant into the Pacific Ocean has unilaterally reversed a decade of nuclear safety reform in Japan. Although providing information to foreign embassies in Tokyo and online social networks, the Japanese government has failed to allay domestic concerns and rising international pressure.

The Tokyo Electric Power Company (TEPCO) proposes to use an Advanced Liquid Processing System (ALPS) to remove all the radionuclides from the wastewater except tritium — which poses the lowest health risk. It will then dilute the tritium concentration until levels are safe enough for release into the Pacific Ocean.

Japan’s Ministry of Economy, Trade and Industry and TEPCO, with the backing of the International Atomic Energy Agency (IAEA) and other experts, claim that this ‘dilution and discharge option’ is technically feasible and safe. Since the ALPS operations started in 2013, TEPCO has insisted that releasing treated water into the ocean is a normal part of nuclear plant operations around the world.

But the water directly injected into the cooling process of the damaged reactors and fuel debris is different from the water normally used for cooling nuclear plants. Japan’s Nuclear Regulation Authority (NRA) has described this cooling process as free-flowing (kakenagashi) because of its direct contact with the damaged reactors. The used cooling water from the Fukushima plant is much more radioactive than that from a normal operation.


A 2018 TEPCO report revealed that even after filtration the treated water still contained other radionuclides, such as strontium-90 and iodine-129, above regulatory-limit levels. In September 2020, TEPCO began to carry out secondary treatment tests on the water to reduce the amount of radioactive substance it contained.

Japanese Prime Minister Yoshihide Suga stated, ‘the disposal of ALPS treated water is unavoidable and experts have recommended that the release into the sea is the most realistic method’. If good nuclear safety governance is concerned with bringing stakeholders together to meet social needs, then the prime minister’s remark falls short.

Referring to ‘expert opinion’ as the main factor in the decision making process can be seen as a political strategy to avoid blame. The Suga cabinet is unwilling to take political responsibility for releasing the wastewater into the Pacific Ocean. The potential threats to human health and the environment call for closer scrutiny of Japan’s leadership………

TEPCO needs to regain public trust by exercising transparency and providing accurate and reliable information about the current state of radionuclides contained in each water storage tank at Fukushima Daiichi. The Japanese government should produce a clear technical plan at the operational level and an environmental impact report for stakeholders. The Japanese government and TEPCO should also actively seek views from all relevant stakeholders — including those in other countries — and show that their concerns are being adequately addressed…….https://www.eastasiaforum.org/2021/06/29/japans-nuclear-wastewater-plan-is-clouded-by-politics/

NASA pretending that space radiation is sort of OK for women, but it’s not

New NASA radiation standards for astronauts seen as leveling field for women, Science, By Anil OzaJun. 29, 2021 

A blue-ribbon panel has endorsed NASA’s plans to revise its standard for exposing astronauts to radiation in a way that would allow women to spend more time in space.


A report by the U.S. National Academies of Sciences, Engineering, and Medicine released on 24 June encourages NASA to proceed with its plans to adopt a new standard that limits all astronauts to 600 millisieverts of radiation over their career. The current limit is the amount of radiation that correlates with a 3% increase in the risk of dying from a cancer caused by radiation exposure—a standard that favored men and older astronauts whose cancer risk from radiation was lower. The proposed standard would limit all astronauts to the allowable dosage for a 35-year-old woman.

The changes are in line with current data and puts women on an equal footing, says Hedvig Hricak, a radiologist at Memorial Sloan Kettering Cancer Center and chair of the committee that wrote the report. “There’s no evidence for significant gender difference in the radiation exposure, and associated risk of cancer,” she says.

The new standard comes as NASA gears up for renewed exploration of the Moon and, eventually, a mission to Mars. The change should remove gender from the list of factors used to decide who gets chosen for those missions, says Paul Locke, an environmental health expert at Johns Hopkins University who was not on the committee. “Women will not be penalized because they are, under the old model, at higher risk,” he says.

Whereas some experts lauded NASA’s intentions, others worry the proposal ignores the complexities and uncertainties of deep space travel. “I think they’ve pulled together the best data they have. But again, I think, more research is going to be needed,” says Albert Fornace, a radiobiologist at Georgetown University. With so few people having traveled beyond low-Earth orbit, most of the data for setting radiation exposure limits in space come from survivors of the atomic bombs in Japan and studies of people, like uranium miners, who work in conditions with high exposure to radiation. The long lead time for voyages to Mars also gives scientists time to develop ways to shield astronauts from higher levels of radiation, Fornace adds.

Francis Cucinotta, a biophysicist at the University of Nevada, Las Vegas, doesn’t agree with the report’s backing of a single dosage level. Instead, the former chief scientist for NASA’s radiation program thinks equity should come in the form of equal risk rather than equal dosages of radiation.

“[It] sounds like they’re just going to ignore the science and try to make it comfortable for everybody,” Cucinotta says, arguing that age, sex, and race affect an individual’s risk of developing cancer and should be factors when determining the amount of time astronauts can spend in space. “When they’re selected to be astronauts, there’s a lot of things where it’s not equal—it’s based on performance capability. But they’re not applying that model here.”

Cucinotta would stick with the 3% increase in the risk of dying of cancer. For a Mars mission, which is expected to expose astronauts to 1000 millisieverts, he proposes raising that maximum risk to 5% after conducting research on countermeasures and weighing genetic markers that lower an astronaut’s risk of developing cancer………..    https://www.sciencemag.org/news/2021/06/new-nasa-radiation-standards-astronauts-seen-leveling-field-women

‘Strong Evidence’ Links Uranium Mining to Lung Cancer

The U.S. Nuclear Weapons Program Left ‘a Horrible Legacy’ of Environmental Destruction and Death Across the Navajo Nation   Inside Climate News,  By Cheyanne M. Daniels, Amanda Rooker, June 27, 2021  ”………………….‘Strong Evidence’ Links Uranium Mining to Lung Cancer

Uranium mining began in the Southwest in 1944, when the United States no longer wanted to depend on foreign sourcing of the uranium that was needed for nuclear research and weapons development as part of the Manhattan Project, the secret World War II effort to develop the atomic bomb. The federal government was the sole purchaser of uranium ore until 1971, but private companies operated the mines.

Navajo miners were not fully informed about the dangers of uranium mining specifically, despite the fact that scientists had concluded by the late 1930s that uranium mining caused lung cancer, even if debate existed about exactly why, according to a 2002 study published in the American Journal of Public Health. The miners were not informed about the potential risks of their work.

The investigation focused on white miners, although mortality rates were reported for non-white miners. One study looked at 3,238 white miners, while a second involved 757 non-whites, mainly Navajos. The studies were performed without the consent of the workers. 

In both white and non-white cohorts, “strong evidence” was found for an increased incidence of lung cancer. In the study of 757 non-white miners, 10 deaths were expected, but 34 were documented, meaning researchers found more than three times the number of lung cancer deaths than they expected. 

Tommy Reed, 64, a member of the Navajo Radiation Victims Committee who began working in a uranium mine when he was in high school, said his father was one of the Navajo miners studied. 

“They studied my father and a lot of the men …  and ladies that were in the mines there,” Reed said. “My dad, like many other men that were (miners), spent nine months on a ventilator. How much more of our story can cut deep, where one can comprehend the struggle that we have?”

For Reed, extending the Radiation Exposure Compensation Act isn’t to place blame but to ensure that other miners, uranium workers and downwinders are compensated for illnesses related to radiation exposure. But if he had to place blame, Reed said, he would point to the federal agencies that allowed the mining to take place and the related illnesses to go undiagnosed and untreated. 

“They knew, and they had numbers on them. They studied, it’s on the books, there were human experimentations,” said Reed.

“We’re just five-finger people,” he said, using a Navajo word for human beings. “But these five-finger people are the ones that they relied on, the people that are most expendable.” 

In response to this legacy of environmental destruction, death and racism, the Navajo Nation Council passed the Diné Natural Resources Protection Act in 2005 to mandate that “no further damage to the culture, society and economy of the Navajo Nation occurs because of uranium processing until all adverse economic, environmental and human health effects from past uranium mining” have been eliminated or substantially reduced……………… https://insideclimatenews.org/news/27062021/nuclear-weapons-navajo-nation-uranium-mining-environmental-destruction-health/

NASA wants to increase allowable radiation exposure for astronauts – women affected most.

“As missions go deeper into space, we need to communicate why astronauts are being asked to take on that risk and offer explicit ethical justifications. This report offers a framework for accomplishing that,”

Report backs NASA proposal to change astronaut radiation exposure limits, Space News, by Jeff Foust — June 25, 2021  WASHINGTON — A National Academies committee has endorsed a NASA proposal to change the radiation exposure limits the agency sets for its astronauts but cautioned that the revised limit is still insufficient for human Mars missions.

The June 24 report by a committee established by the National Academies and sponsored by NASA backs the agency’s proposal to set a single lifetime radiation exposure limit for astronauts, rather than different limits based on age and gender.

Currently, lifetime exposure limits range from 180 millisieverts for a 30-year-old woman to 700 millisieverts for a 60-year-old man. Those limits are based on models intended to set a limit of no more than a 3% risk of radiation exposure-induced death (REID) at the 95% confidence level.

NASA proposed changing that to a limit of about 600 millisieverts, regardless of age or gender. That limit is based on the mean 3% risk of REID for a 35-year-old woman, the most conservative case but measured to a different standard than the earlier calculation.

The change, the committee noted, will allow more opportunities for female astronauts given the higher radiation limits. “Taken together, the proposed standard creates equality of opportunity for spaceflight with the trade-offs of somewhat higher allowable exposure to radiation for a subset of astronauts (primarily women) and limiting exposures below otherwise acceptable doses for others (primarily older men),” the committee’s report stated………

While the revised levels will increase flight opportunities for many NASA astronauts, the levels are still more conservative than many other space agencies. Roscosmos, the European Space Agency and the Canadian Space Agency all set lifetime exposure limits of 1,000 millisieverts for their astronauts and cosmonauts, without any age or gender differences. The Japanese space agency JAXA does have age and gender differences, varying between 500 and 1,000 millisieverts.

Even those higher levels fall short of projected radiation exposures for round-trip Mars missions, which the report noted would exceed 1,000 millisieverts. Any astronauts who fly on a Mars mission would need a waiver to NASA’s radiation exposure limits, which raises ethical questions. “NASA should develop a protocol for waiver of the proposed space radiation standard that is judicious, transparent, and informed by ethics,” the committee recommended.

“As missions go deeper into space, we need to communicate why astronauts are being asked to take on that risk and offer explicit ethical justifications. This report offers a framework for accomplishing that,” said Julian Preston of the U.S. Environmental Protection Agency, vice-chair of the committee, in a statement.https://spacenews.com/report-backs-nasa-proposal-to-change-astronaut-radiation-exposure-limits/
