Russia declares ‘state of emergency’ after radiation detected in eastern city of Khabarovsk

Authorities in Russia’s far eastern city of Khabarovsk have declared a state of emergency in an area where a “radiation source” was found, TASS news agency reported on Friday, adding that elevated radiation levels were detected near a power pylon about 2.5 km (1.5 miles) from residential buildings.

Officials have not provided an explanation for the leak but have confirmed its containment and transfer to a secure radioactive waste storage site. A state of emergency is to persist for a minimum of three additional days as law enforcement continues investigations into the incident.

Reports indicate a delay of approximately one week before authorities responded to the leak. Video footage has surfaced depicting an individual in a nuclear protective mask, carrying a radiation reader, which displayed escalating readings as he traversed a designated “waste dump” area.

No one had been injured or exposed to radiation and “there is no threat to the health of citizens”, TASS quoted the local branch of Russia’s consumer safety watchdog as saying.

It said radiation levels would be monitored for the next two days and the source of the radiation would be investigated.

WHERE HAVE ALL THE INSECTS GONE? Satellites are taking them, every one.

The least noticed and greatest assault on Earthly life rains on us from the sky. Nature’s wires strung above us from horizon to horizon, carrying the electricity that helps power our bodies, and the information that informs our growth, healing, and daily lives, now carries dirty electricity — millions of frequencies and pulsations that confuse our cells and organs, and dim our nervous systems, be we humans, elephants, birds, insects, fish, or flowering plants.

The pulsations pollute the Earth beneath our feet, surround us in the air through which we fly, course through the oceans in which we swim, flow through our veins and our meridians, and enter us through our leaves and our roots. The planetary transformer that used to gentle the solar wind now agitates, inflames.

The lake pictured above is the United Kingdom’s largest. Located in Northern Ireland, Lough Neagh swarms so densely with flies every spring and summer that residents shut their windows against the living smoke. Clothes left out on a line are covered with them. So is any windshield on a vehicle traveling around the lough’s 90-mile shoreline. Until 2023.

Last year, unbelievably, no flies were to be seen. Windshields and hanging clothes were bare of them. None flew into open windows. Other species that used to eat them were gone as well — ducks, frogs, fish, eels, and predatory insects. Fly larvae were not there to keep the lake bottom clean. Little was alive in the lough except an overgrowth of algae. “Has the ecosystem of the UK’s largest lake collapsed?” asked The Guardian in a February 19, 2024 article.

Has the ecosystem of the entire Earth collapsed? we ask, for the same is happening all over, according to reports I have been receiving for a year from almost everywhere on every continent.

56 Years of Global Vandalism

On June 13, 1968, the United States completed its launch of the world’s first constellation of military satellites. Twenty-eight of them, more than twice as many satellites as were in orbit around the Earth until then, were lofted to an altitude of 18,000 miles, in the heart of the outer Van Allen radiation belt. The “Hong Kong” flu pandemic began two weeks later and lasted for almost two years.

For the next three decades, the skies slowly filled up with hundreds of satellites, mostly for military purposes. Then in the late 1990s, cell phones became popular.

On May 17, 1998, a company named Iridium completed its launch of a fleet of 66 satellites into the ionosphere, at an altitude of only 485 miles, and began testing them. They were going to provide cell phone service to the general public from anywhere on earth. Each satellite aimed 48 separate beams at the earth’s surface, thus dividing the planet into 3,168 cells. Reports of insomnia came from throughout the world………………………………………………………………

SpaceX has been launching rockets carrying dozens of satellites at a time on a weekly or biweekly basis, filling the heavens with luminous objects that interfere with astronomy, spewing chemicals that are destroying our planet’s protective ozone layer, filling the upper layers of the atmosphere with water vapor that should not be there and that is increasing the current in the global electric circuit and the violence of thunderstorms, and cluttering up space with satellites that are nothing but solar arrays and computers that are continually failing, wearing out, and having to be replaced, and which are deorbited to burn up in the lower atmosphere, filling it with metals and toxic chemicals for everyone to breathe — and altering the electromagnetic environment of the Earth that had not changed in three billion years and that life below depends on for its vitality and survival.

Last Thursday morning, from Boca Chica, Texas, SpaceX successfully launched its Starship — the largest rocket ever built, the one it wants to ferry men and women to Mars with — into space for the first time.  And on Friday it launched yet another 23 Starlink satellites to bring its total polluting the ionosphere up to more than 6,000, now not only for internet communication with rooftop dishes but for direct communication with handheld cell phones. The 6,000 satellites are also now communicating directly with one another, wrapping the Earth with pulsating lasers carrying 42 million gigabytes of data every single day………

Since March 24, 2021, not only has human health deteriorated, but the biodiversity of the Earth, everywhere, has plummeted. People have not so much noticed the decline of the larger wildlife like wolves, bears, lions and tigers, which were already scarce, but they are shocked by the total disappearance of the smallest animals that were only recently so common you couldn’t open your windows without them flying in. They are shocked by the disappearance of all the frogs that used to swim in their ponds, the birds that used to nest in their trees, the worms that used to slither on the ground, the insects that used to fly through their windows and cover their clothes hanging on the line. My newsletters of March 29, June 21, September 20, October 17, and November 28, 2023 carried major stories about this from various parts of the world. My newsletters of December 5 and December 26, 2023, and January 9 and February 6, 2024 quoted from individuals all over the world who have emailed or called me, and I have a huge backlog of more such reports that you can read when I publish them in the future.

If we want to have a planet to live on, not only for our children but for ourselves, the [electromagnetic]radiation has to stop. Not only do the cell towers have to come down that are so ugly to look at, but also the cell phones that we hold in our hands and have become so dependent on, and the satellites that are squeezing all the life that remains out from under them. We are running out of time.  https://cellphonetaskforce.org/where-have-all-the-insects-gone/

The horrors of nuclear weapons testing

I think that enough time has gone by that the longer-term dangers of nuclear weapons, such as radioactive fallout, have largely disappeared from the public consciousness—much to the agony and despair of those afflicted to this day.

Radioactive fallout and its long-term effects—things that the average person today does not really appreciate—would be the result from any future nuclear weapons explosion that touched the Earth’s surface. Fallout does not just affect the target, but also the surrounding areas—which could be as far as hundreds of miles away. And the effects could last for years, if not decades thereafter.

Bulletin By Walter Pincus, March 7, 2024

There has been talk in the national security community lately about the so-called “merits” of resuming underground or even atmospheric nuclear weapons tests. I think this would be a grave mistake for many reasons—chief among them is that it forgets the horrific health effects that resulted from some previous nuclear tests.

To be clear, since 1963, atmospheric tests of nuclear weapons have been banned, as have tests in outer space and under water. And underground explosive tests have been banned ever since the 1996 Comprehensive Nuclear Test Ban Treaty, or CTBT. (Technically speaking, while the United States and China have signed the CTBT, neither has ratified it. Russia did both sign and ratify the treaty but on November 2, 2023 Russia announced it had rescinded its ratification. All three countries, however, have so far abided by the CTBT treaty.)

Meanwhile, sub-critical nuclear tests—which use tiny amounts of plutonium but do not create self-sustaining, exponentially-growing, nuclear chain reactions—have continued to this day, in laboratories or in specially constructed underground tunnels. The US is building new tunnels for sub-critical tests at the Nevada Nuclear Test Site where they are expected to help in designing the new, US W93 nuclear warhead now under development.

Presumably, then, what we are referring to when we talk about the possible resumption of nuclear testing is not the latter sub-critical testing, but some version of atmospheric, outer space, underwater, or underground explosives testing.

And here things get tricky.

Because I think that enough time has gone by that the longer-term dangers of nuclear weapons, such as radioactive fallout, have largely disappeared from the public consciousness—much to the agony and despair of those afflicted to this day.

I believe that the more people understand and even can visualize the immediate and long-term dangers of nuclear weapons use, the less likely it is that they may be used. Several nuclear scientists have told me they have memories of specific past nuclear atmospheric tests, most memorably two who were involved in the Manhattan Project—Harold Agnew and Hans Bethe.

Agnew photographed the Hiroshima mushroom cloud from the US aircraft that followed the Enola Gay that dropped the atomic bomb. Agnew almost always brought up the effect that had on him when we met.

For his part, Bethe, at 88—on the 50th anniversary of the birth of the atomic bomb—wrote: “I feel the most intense relief that these weapons have not been used since World War II, mixed with horror that tens of thousands of such weapons have been built since that time—one hundred times more than any of us at Los Alamos could ever imagine.”

In an interview years earlier at Cornell University where he was teaching, Bethe had told me something similar—and at 91, I have never forgotten those words.

The closer you are to nuclear weapons, the more you are aware of the dangers if they were to be used again. However, I believe, most people today have forgotten, if they ever knew, what a single nuclear weapon could do.

Seeing is believing. But believing in this case should make you work to oppose their use, as can be seen in a very rough sort of timeline of my own life…………………………………………………………………………………………………………………

It was in February 1966, well after the 1963 atmospheric test ban treaty, that I first wrote about the impact of nuclear weapons. It was a rather flip, three-paragraph note in The Reporter Magazine, which no longer exists. The story concerned a law that had passed Congress the previous month, a measure which required the US Government to pay $11,000 to each of the 82 men, women and children—or their survivors—who had been on Rongelap Atoll in the Marshall Islands in the central Pacific on March 1, 1954 when the United States detonated Test Bravo from a tower on an artificial island built within Bikini Atoll, more than 120 miles west of Rongelap.

Bravo was the first US test of a deliverable thermonuclear bomb and was expected to have a six-megaton yield, the equivalent of six million tons of TNT. In fact, the explosion was more than double that—15 megatons—and one thousand times more powerful than the atomic bomb that destroyed Hiroshima.

Thanks in good part to thousands of documents on nuclear weapons declassified and released during the Clinton Administration, I was able to describe details about the Bravo explosion two years ago in my book, Blown To Hell: America’s Deadly Betrayal of the Marshall Islanders, as follows:

In a few seconds the fireball, recorded at one hundred million degrees, had spread nearly three miles in diameter, then quickly spread to ten miles. The sandspit and nearby reef where Bravo had stood, along with coral island areas, were vaporized down almost two hundred feet into the sea, creating a crater about one mile in diameter.

It was estimated that three hundred million tons of vaporized sand, coral and water shot up into the air as the fireball rose, and one-hundred-mile-an-hour winds created by the blast pulled additional debris up into the fireball. Within one minute, the fireball had gone up forty-five thousand feet with a stem four miles wide filled with radioactive debris. It continued to zoom upward, shooting through the troposphere and into the stratosphere within five minutes.

Later data showed the cloud bottom was at fifty-five thousand feet, the secondary mushroom cloud bottom was at one-hundred-fourteen thousand feet, and the upper cloud hit one-hundred-thirty thousand feet.

Ten minutes after detonation the mushroom cloud had widened and measured seventy-five miles across just below the stratosphere.

Original projections had predicted Bravo radioactive fallout would emanate from a fifteen-mile-wide cylinder that could stretch into the stratosphere. Instead, it turned out to be a one-hundred-mile-wide cloud where “debris was carried up and dispersed over a much larger area than was thought possible,” wrote Dr. William Ogle, the test’s task force commander of the scientific group that dealt with radioactivity.

Radioactive fallout and its long-term effects—things that the average person today does not really appreciate—would be the result from any future nuclear weapons explosion that touched the Earth’s surface. Fallout does not just affect the target, but also the surrounding areas—which could be as far as hundreds of miles away. And the effects could last for years, if not decades thereafter. These effects are worth spelling out in detail, using what happened downwind of the test as an example.

That March 1, 1954 morning, the Japanese fishing boat Lucky Dragon, with a crew of 23 aboard, was trawling its nets 90 miles east-northeast of Bikini. A crewman at the stern rail saw a whitish flare in the west that briefly lit up the clouds and the water. It grew in size, turned to yellow-red, then orange. After a few minutes, the colors faded and shortly thereafter the ship was rocked by the blast of an explosion.

The Lucky Dragon’s captain and the fishing master, who had read ship warnings before they left port, realized they might have strayed into a nuclear test area. They quickly decided to haul in their fishing nets and head back to Japan, almost 2,500 miles away.

It was another two or three hours before a fine white dust began to come down on the boat. With a light rain, the radioactive dust continued to settle on crewmen and the fish on the deck as they worked for another two hours to bring in their lines.

On Rongelap about 30 miles further east, at about 11:30 a.m., a similar powdery, radioactive ash began falling in the area. It stuck to the Marshallese people’s skin, hair, and eyes; many walked barefoot and the powder stuck to their toes; it fell on fish drying on wooden racks that would be eaten that night. Rain briefly fell as the fallout continued into afternoon, dissolving the powdery ash on roofs and carrying it down drains into water barrels that provided drinking water to each household.

On parts of Rongelap Island, where most people lived, the almost five hours of fallout led to drifts of up to one-inch or more high on the ground, on roofs, and along the beach. People recalled that when the moon broke through the clouds that night, it looked like patches of snow on the ground.

It would be two days before the Marshallese were evacuated from Rongelap and taken to the Kwajalein Navy Base by a US Navy destroyer. By then, most of the Rongelapese people had suffered from acute radiation exposure and nausea; some had experienced skin lesions as well.

Since the Bravo test was highly classified, a decision was made in Washington to keep the fallout incident secret, although the Atomic Agency Commission (AEC) had released a statement on March 1, 1954 that a nuclear test had taken place in the Marshall Islands Pacific Proving Ground. That had generated a small front page story in the March 2, 1954, edition of The New York Times. It was not until March 11, 1954, that the AEC admitted people “unexpectedly exposed to some radioactivity” had been moved to Kwajalein “according to a plan as a precautionary measure.”

Two weeks passed before the Lucky Dragon returned to its home port in Japan. It was only then that on March 16, 1954, the first story appeared in the Japanese Yomiuri Shimbun newspaper of what had happened to the boat’s crew and their fish—not what happened to the Marshallese. That story immediately triggered initial worldwide attention to the dangers of fallout from nuclear weapons.

However, it was not until President Eisenhower’s March 31, 1954 press conference that AEC Chairman Lewis Strauss, who had just returned from observing post-Bravo nuclear tests, admitted publicly that the Bravo test was “in the megaton range” and “the yield was about double that of the calculated estimate.” ……………………………………………………………………………………………………….

The early part of the 1955 report described the blast and heat effects of early atomic bombs detonated in the air, before discussing fallout from Bravo and other detonations. “In the air explosion, where the fireball does not touch the earth’s surface, the radioactivity produced in the bomb condenses only on solid particles from the bomb casing itself and the dust which happens to be in the air. In the absence of materials drawn up from the surface, these substances will condense with the vapors from the bomb and air dust to form only the smallest particles. These minute substances may settle to the surface over a very wide area—probably spreading around the world—over a period of days or even months. By the time they have reached the earth’s surface, the major part of their radioactivity has dissipated harmlessly in the atmosphere and the residual contamination is widely dispersed.”

The report then turned to what fallout would occur if the fireball hit the ground. “If however the weapon is detonated on the surface or close enough so that the fireball touches the surface, then large amounts of material will be drawn up into the bomb cloud. Many of the particles thus formed are heavy enough to descend rapidly while still intensely radioactive. The result is a comparatively localized area of extreme radioactive contamination, and a much larger area of some hazard. Instead of wafting down slowly over a vast area, the larger and heavier particles fall rapidly before there has been an opportunity for them to decay harmlessly in the atmosphere and before the winds have had an opportunity to scatter them.”

It described the Bravo fallout as looking like snow “because of calcium carbonate from coral,” and then noted its “adhesive” quality thanks to moisture picked up in the atmosphere as it descended. In the end it contaminated “a cigar-shaped area extending approximately 220 statute miles downwind, up to 40 miles wide,” from Bikini. It “seriously threatened the lives of nearly all persons in the area who did not take protective measures,” the report said.

The report then talked about radioactive strontium in fallout as having a long, average lifetime of nearly 30 years, noting it could enter the human body either by inhaling or swallowing. Deposited directly on edible plants, the strontium could be eaten by a human or animal. While rainfall or human washing of the plants would remove most of the radioactive material, radioactive strontium deposited directly on the soil or in the ocean, lakes, or rivers could be taken up by plants, animals, or fish. There it would lodge in their tissue where it could later be eaten by humans…………….

The other radioactive element in fallout described specifically as a threat in the report was radioactive iodine. Even though the average life of radioactive iodine was only 11.5 days, it was described as a serious hazard because, if inhaled, it concentrated in the thyroid gland where it could damage cells, depending on dosage………………………………………………………………………………………………………………………………………………………………..

Back on Rongelap, despite some cleanup, there are few in residence. A study published in the Proceedings of the National Academy of Sciences in July 2019, done by researchers from Columbia University, found that levels of plutonium and cesium in the soil on Rongelap and other Marshall Island atolls were “significantly higher” than levels that resulted from fallout existing from the July 1986 Chernobyl nuclear power accident—which occurred 28 years after US nuclear tests had ended in the Marshalls.

The Rongelap Marshallese as well as the Japanese seamen who were exposed to fallout on March 1, 1954, can be seen as surrogates for anyone caught in a future nuclear war. Rongelap Atoll, as well as Bikini Atoll, for the most part still cannot be inhabited despite attempts to decontaminate them. Think of what today’s cities would be like if hit by a thermonuclear weapon whose fireball struck the ground and created radioactive fallout.

Within weeks it will be 70 years since the Bravo test. The more the US public and the world are reminded of that test and the resulting Rongelap story, the more they should work to deter any potential use of nuclear weapons.  https://thebulletin.org/premium/2024-03/the-horrors-of-nuclear-weapons-testing/?utm_source=Newsletter&utm_medium=Email&utm_campaign=ThursdayNewsletter03072024&utm_content=NuclearRisk_NuclearTestingHorrors_03072024

“Tritium Removal” A Report on the Proposed MCECE nuclear Facility at Chalk River

“Tritium Removal” A Report on the Proposed MCECE Facility at Chalk
River by Gordon Edwards, Ph.D. for the Keboawek First Nation. In a letter
to Keboawek First Nation dated February 2, 2024 (reference # 2), we read
that “CNL is restoring and protecting Canada’s environment by reducing
and effectively managing nuclear liabilities.

Among these liabilities is
Atomic Energy of Canada’s (AECL) large inventory of tritium contaminated
heavy water.” In an accompanying Fact Sheet (reference # 3) CNL states
that “tritiated heavy water cannot be used, re-used or disposed of in its
current form.”

The fact that tritium-contaminated heavy water cannot be
used, re-used, or even disposed of in its present form is a testament to
the considerable hazards posed by radioactive tritium. Nevertheless,
tritiated heavy water can be safely stored, and kept out of the
environment, as is being done at present. There is no reason given by CNL
as to why such storage cannot be continued indefinitely, until the
radioactive tritium has disintegrated to innocuous levels.

Breakthrough research unveils effects of ionizing radiation on cellular DNA

Feb 14 2024The Korea Advanced Institute of Science and Technology (KAIST)

Recent release of the waste water from Japan’s Fukushima nuclear disaster stirred apprehension regarding the health implications of radiation exposure. Classified as a Group 1 carcinogen, ionizing radiation has long been associated with various cancers and genetic disorders, as evidenced by survivors and descendants of atomic bombings and the Chernobyl disaster. Despite much smaller amount, we remain consistently exposed to low levels of radiation in everyday life and medical procedures.

Radiation, whether in the form of high-energy particles or electromagnetic waves, is conventionally known to break our cellular DNA, leading to cancer and genetic disorders. Yet, our understanding of the quantitative and qualitative mutational impacts of ionizing radiation has been incomplete.

On the 14th, Professor Young Seok Ju and his research team from KAIST, in collaboration with Dr. Tae Gen Son from the Dongnam Institute of Radiological and Medical Science, and Professors Kyung Su Kim and Ji Hyun Chang from Seoul National University, unveiled a breakthrough. Their study, led by joint first authors Drs. Jeonghwan Youk, Hyun Woo Kwon, Eunji Kim and Tae-Woo Kim, titled “Quantitative and qualitative mutational impact of ionizing radiation on normal cells,” was published in Cell Genomics.

Employing meticulous techniques, the research team comprehensively analyzed the whole-genome sequences of cells pre- and post-radiation exposure, pinpointing radiation-induced DNA mutations. Experiments involving cells from different organs of humans and mice exposed to varying radiation doses revealed mutation patterns correlating with exposure levels. 

Notably, exposure to 1 Gray (Gy) of radiation resulted in on average 14 mutations in every post-exposure cell. Unlike other carcinogens, radiation-induced mutations primarily comprised short base deletions and a set of structural variations including inversions, translocations, and various complex genomic rearrangements. (Figure 3) Interestingly, experiments subjecting cells to low radiation dose rate over 100 days demonstrated that mutation quantities, under equivalent total radiation doses, mirrored those of high-dose exposure. ……………………………………….. more https://www.news-medical.net/news/20240214/Breakthrough-research-unveils-effects-of-ionizing-radiation-on-cellular-DNA.aspx

Radiation heroes

In this Energy Revolutions podcast David Toke talks to Dr Ian Fairlie
about two scientists who were persecuted for uncovering dangerous
radioactive truths. The first scientist to be discussed is Alice Stewart.
She discovered that routine X-rays used on pregnant women were harming
unborn babies. Initially, she was dismissed, derided, and forced to leave
her job. Later her work was quietly recognised as being correct. On the
other hand, Yury Bandachevsky was jailed by the Government of Belarus for
insisting on researching and publishing on the impact of the Chernobyl
nuclear accident.

Exposure to CT Radiation and Risk of Blood Cancers in Young Patients

By The ASCO Post Staff, 11/14/2023 

Investigators may have uncovered an association between exposure to computed tomography (CT) radiation in young patients and an increased risk of hematologic malignancies, according to a recent study published by Bosch de Basea Gomez et al in Nature Medicine. These recent findings highlighted the significance of continuing to apply strict radiologic protection measures in young patients.  

Background

Currently, more than 1 million young patients in Europe undergo CT scans each year. The impact of these scans in patient management—including diagnostic efficacy, treatment planning, and disease follow-up—is generally considered positive. However, the extensive use of this procedure in recent decades has raised concerns in the medical and scientific community about the potential cancer risks associated with exposure to ionizing radiation, particularly in young patients.

“The exposure associated with CT scans is considered low (< 100 mGy), but it is still higher than for other diagnostic procedures,” explained senior study author Elisabeth Cardis, PhD, Head of the Radiation Group at the Barcelona Institute for Global Health.

Previous studies have suggested that young patients exposed to CT scans may have an increased risk of developing cancer, but these studies faced several methodologic limitations.

Study Methods and Results

In the recent multinational EPI-CT study, the investigators—including clinicians, epidemiologists, and dosimetrists from Belgium, Denmark, France, Germany, the Netherlands, Norway, Spain, Sweden, and the United Kingdom—analyzed the data of 984,174 patients who underwent at least one CT scan prior to age 22 to address the limitations of the previous research.

The dose of radiation delivered to the bone marrow was estimated for each of the patients. By linking this information to national cancer registries, the investigators were able to identify those who developed hematologic malignancies after an average follow-up of 7.8 years. However, for those who had CT scans in the early years of the technology, the investigators were able to monitor cancer incidence for more than 20 years after their first scan.

The investigators determined there was a clear correlation between the total radiation doses to the bone marrow from CT scans and the risk of developing both myeloid and lymphoid malignancies. A dose of 100 mGy multiplied the risk of developing a hematologic malginancy by a factor of about three. The investigators suggested that a typical scan today (with an average dose of about 8 mGy) may increase the risk of developing hematologic malignancies by about 16%………………………………………………. more https://ascopost.com/news/november-2023/exposure-to-ct-radiation-and-risk-of-blood-cancers-in-young-patients/

Frozen fallout: radioactive dust from accidents and weapons testing accumulates on glaciers.

Physics World, 20 Jun 2023 James Dacey

Glacier surfaces in certain parts of the world contain concerning amounts of toxic radioactive materials, a result of weapons testing and nuclear accidents such as the Chernobyl disaster in 1986. Fallout radionuclides accumulate within cryoconite – a granular sediment found in holes on glacier surfaces – and there is a risk of this material entering local ecosystems as glaciers melt due to climate change. Glaciologists and ecologists say this poses urgent questions. What regions are at highest risk? How diluted is the nuclear material entering proglacial zones? What impact might that have on organisms?…..

Classified! The secret radiation files.

most of the exposure people received came in the form of internal exposures from ingesting radioactivity, not from exter­nal, ambient gamma rays in the environment.

Medical examinations of people in contaminated regions showed a significant increase in the general number of chromosomal mutations in newborns, and the frequency of birth defects in southern Belarus was found to be significantly higher than the control. In terms of general health, Konoplia reported, adults showed an increase in diseases of the circulatory system, hyperten­sion, coronary illness, heart attacks, and myocardial problems, plus a rise in respiratory diseases.

Researchers on the UN team who had security clearances had access to classified studies that showed that 79 percent of children in the Marshall Islands exposed to American bomb blasts under the age of ten had developed thyroid cancer. Seventy-nine percent of several hundred children had thyroid cancer when the background rate was one in a million.

Health physicists fear lawsuits more than nuclear accidents

By Kate Brown, 12 Nov 23,  https://beyondnuclearinternational.org/2023/11/12/classified-the-secret-radiation-files/

In 1987, a year after the Chernobyl accident, the US Health Physics Society met in Columbia, Maryland. Health physicists are scientists who are responsible for radiological protection at nuclear power plants, nuclear weapons plants, and hospitals. They are called on in cases of nuclear accidents. The conference’s keynote speaker came from the Department of Energy (DOE); the title of his talk drew on a sports analogy: “Radiation: The Offense and the Defense.” Switching metaphors to geopolitics, the speaker announced to the hall of nuclear professionals that his talk amounted to “the party line.” The biggest threat to nuclear industries, he told the gathered professionals, was not more disasters like Chernobyl and Three Mile Island but lawsuits.

After the address, lawyers from the Department of Justice (DOJ) met in break-out groups with the health physicists to prepare them to serve as “expert witnesses” against claimants suing the US government for alleged health problems due to exposure from radio­activity issued in the production and testing of nuclear weapons during the Cold War. That’s right: the DOE and the DOJ were preparing private citizens to defend the US government and its corporate contractors as they ostensi­bly served as “objective” scientific experts in US courts.

Health physics is an extremely important field for our everyday lives. Health physicists set standards for radiation protection and evaluate damage after nuclear emergencies. They determine where radiologists set the dial for CT scans and X-rays. They calculate how radioactive our food can be (and our food is often radioactive) and determine acceptable levels of radiation in our workplaces, environments, bodies of water, and air. Despite its importance, as it is practiced inside university labs and government organizations, health physics is far from an independent field engaged in the objective, open-ended pursuit of knowledge.

Compromised Science

The field of health physics emerged inside the Manhat­tan Project along with the development of the world’s first nuclear bombs. From the United States, it migrated abroad. For the past seventy-five years, the vast major­ity of health physicists have been employed in national nuclear agencies or in universities with research under­written by national nuclear agencies. As much as we in the academy like to make distinctions between apoliti­cal, academic research and politicized paid research outside the academy, during the Cold War those distinc­tions hardly made sense. From the end of World War II until the 1970s, federal grants paid for 70 percent of university research. The largest federal donors were the Department of Defense, the US Atomic Energy Agency, and a dozen federal security agencies.

Historian Peter Galison estimated in 2004 that the volume of classified research surpassed open literature in American libraries by five to ten times. Put another way, for every article published by American academics in open journals, five to ten articles were filed in sealed repositories available only to the 4 million Americans with security clear­ances. Often, the same researchers penned both open and classified work. Health physics benefited from the largesse of the Pentagon and the Atomic Energy Com­mission, which produced nuclear weapons for US arse­nals. Correspondingly, the field suffered from a closed circle of knowledge that has had a major impact on our abilities to assess and respond to both nuclear emergen­cies and quotidian radioactive contamination.

Tracking the production of knowledge in the field of health physics shows how the effective renunciation of facts has played a major role in this branch of science. More generally, it demonstrates how the boundary between open and classified research is critical yet rarely acknowledged. The response of international health physicists to the Chernobyl disaster, which occurred in Soviet Ukraine in April 1986, shows heavily politicized science in action. History reveals that the official, feder­ally sponsored cultivation of “alternative facts” is not new but has deep roots in the twentieth century.

Chernobyl came at an unfortunate time for nuclear professionals. As the Cold War creaked to an end, law­suits abounded. In the 1980s, Marshall Islanders—their homes blasted in nuclear tests, their bodies subjected to classified medical study by scientists contracted by the Atomic Energy Agency—went to court. In Utah and Nevada, those who lived downwind from the Nevada Test Site were lining up for lawsuits. Meanwhile, the Metropolitan Edison Company in Pennsylvania faced lawsuits from plaintiffs living near the Three Mile Island nuclear power plant, which suffered a partial meltdown in 1979.

 In the late 1980s, reporters and congressional investigators began to inquire into US government agencies’ wide-scale engagement in human radiation experiments, which included exposing tens of thou­sands of soldiers to nuclear blasts. These legal actions and investigations constituted an existential threat for nuclear industries, civilian and military. Chernobyl cast into doubt industry statements that nuclear energy is safer than coal, than flying, than living in high-altitude Denver. If another nuclear accident were to occur, UN International Atomic Energy Agency (IAEA) head Hans Blix told the IAEA board of governors a few weeks after the Chernobyl explosions, “I fear the general public will no longer believe any contention that the risk of a severe accident was so small as to be almost negligible.”

Because radioactivity is insensible, society relies on scientists and their technologies to count ionizing radiation and analyze its effect on biological organ­isms. In 1986, the three-decades-old Life Span Study of Japanese bomb survivors served in the West as the “gold standard” for radiation exposure. It became the chief referent in lawsuits over health damage from radioactive contaminants. The Life Span Study started in 1950. In subsequent decades, American and Japanese scientists followed bomb survivors and their offspring, looking for possible health effects from exposure to the bomb blasts. By 1986, the group had detected a signifi­cant increase in a handful of cancers and, surprisingly, no birth defects, though geneticists had expected them.

The Life Span Study told scientists a great deal about the effects of a single exposure of a terrifically large blast of radiation lasting less than a second but little about the impact of chronic, low doses of radioactivity—the kind of exposures served up by the Chernobyl accident and related to the ongoing lawsuits in the United States. At the time, like now, scientists confessed they knew very little about the effects of low doses of radioactivity on human health. For that reason, after Chernobyl, leading scientific administrators in UN agencies and national health agencies called for using the Chernobyl accident to carry out a long-term, large-scale epidemiological study to determine the effects of low doses of radiation on human health. Unfortunately, those requests went nowhere at first because Soviet officials asserted that health damage was limited to the two dozen firefighters who died from acute radiation poisoning. They insisted that they were monitoring the health of neighboring residents and found no change in their health. Soviet spokespeople told the international community that they did not need help, thank you very much.

Silos of Knowledge

Health physics, a moribund field in the West and a secretive field in the Soviet Union, suddenly appeared in the spotlight after the Chernobyl accident. Archival records show that two silos of knowledge about the ef­fects of low doses of radiation on human health emerged in the wake of the Chernobyl accident. Western health physicists oriented around the Life Span Study, while Soviet health physicists worked from specialized, closed clinics producing literature that mostly was filed in clas­sified libraries. A few months after the accident, Western health physicists— extrapolating from Hiroshima—an­nounced that, given the reported levels of radioactivity released in the accident, they expected to see no detect­able health problems as a result. From the Soviet side, spokespeople gave vague assurances, but scientists were silent. For security reasons, Soviet health physicists did not take the podium. Anyway, they were busy.

Behind the Iron Curtain, Soviet scientists near the accident quietly got to work figuring out the extent of the damage. A few days after the accident, Anatolii Romanenko, minister of health in Ukraine, called up medical brigades to examine evacuees and villagers in contaminated areas. Several thousand doctors and nurses fanned out across the Soviet countryside. The effort would have been unimaginable outside of a socialist state highly skilled in the art of mass mobilization. In Ukraine alone, doctors examined seventy thousand children and over one hundred thousand adults in the summer following the accident. People judged to have received high doses were sent to hospitals in Kiev, Leningrad, and Moscow. By late May, the number of hospitalized citizens rose to the tens of thousands.

For the subsequent five years, the last years of the Soviet Union, doctors and medical researchers in Ukraine and Belarus tracked health statistics in contaminated regions. They reported the results in classified documents each year. Their reports show that after the accident, frequencies of health problems in five major disease categories grew annually. Soviet doctors did not have access to ambient measurements of radioactivity in the environment and the food chain because that information was classified, so doctors did what they had long done in the Soviet Union. They used their patients’ bodies as biological barometers to determine doses of radioactivity. Medical practitioners counted white and red blood cells, held radiation detec­tion counters to the thyroids of their patients, measured blood pressure, and scanned urine. They looked for chromosomal damage in blood cells and counts of radioactivity in tooth enamel. Using these biomarkers, Soviet doctors determined the doses of radioactivity their patients had encountered externally and ingested internally. Doctors calculated the range of radioactive isotopes lodged in their patients’ bodies. A KGB general who ran his own KGB clinic in Kiev for KGB agents and their families counted twelve different radioactive isotopes in organs and tissue of his patients.

In 1986, in neighboring Belarus, which received the majority of Chernobyl fallout, scientists at the Belarusian Academy of Science set up case-control studies to track the impact in real time on the health of children and pregnant women, two populations judged to be especially vulnerable. The academy also commissioned dozens of studies of radioactive contamination in the atmosphere, soils, plants, agricultural products, and live­stock. They drew on a body of knowledge that Soviet scientists had clandestinely developed over four decades in clinics stationed near secret nuclear installations that had suffered a large number of accidents and spills of radioactive effluents during the Cold War rush to produce weapons. In April 1989, the respected president of the Belarusian Academy of Science sent to Moscow a twenty-five-page report that reflected the renaissance of science in the fields of radioecology and radiobiol­ogy that had flourished in the contaminated regions as a result of the Chernobyl disaster. Evgenii Konoplia laid out what his Institute of Radiobiology had found.

Almost the entire territory of Belarus had been con­taminated, Konoplia wrote, except for a few northern regions.

Fukushima nuclear plant workers sent to hospital after being splashed with tainted water

Guardian, 27 Oct 23

The operator Tepco says the workers came in contact with the wastewater when a hose came off accidentally and have been taken to hospital as a precaution

Four workers at the Fukushima nuclear plant were splashed with water containing radioactive materials, with two of them taken to hospital as a precaution, according to the plant operator.

The incident, which took place on Wednesday, highlights the dangers Japan still faces in decommissioning the plant. The reactor was knocked out by an immense tsunami in 2011 in the world’s worst atomic disaster since Chornobyl in 1986.

Five workers were cleaning pipes at the system filtering wastewater for release into the sea when two were splashed after a hose came off accidentally, according to a spokesperson for operator Tepco.

Two others were contaminated when they were cleaning up the spill, the spokesperson added………

Tepco said that both would stay in hospital for “about two weeks” for follow-up examinations and that the company was analysing how the accident had occurred while reviewing measures to prevent a repeat of it………………………

Multiple radionuclides detected in Fukushima nuke wastewater planned for 3rd round of ocean discharge

Xinhua 21 Oct 23  https://www.chinadaily.com.cn/a/202310/21/WS65339e99a31090682a5e9ef2.html

TOKYO — The third batch of Fukushima nuclear-contaminated water to be released during Japan’s next round of ocean discharge contains carbon-14, cobalt 60, strontium-90 and other radionuclides, according to pre-discharge test results released by the Tokyo Electric Power Company (TEPCO).

Despite mounting concerns and opposition among local fishermen as well as from other countries, TEPCO said that preparations for the third round of ocean discharge will begin after the second round of discharge is completed and relevant maintenance and confirmation operations are carried out.

The nuclear-contaminated wastewater from the crippled Fukushima Daiichi nuclear power plant, after advanced liquid processing system (ALPS) treatment, must enter the measurement and confirmation facility and wait for pre-discharge test results before being discharged into the ocean.

The measurement and confirmation facility is split into three groups of 10 tanks with each of the groups used on a rotating basis as receiving tanks, measurement and confirmation tanks, and discharge tanks.

At present, the 10 tanks in Group B were emptied in the first round of discharge starting on Aug 24. Meanwhile, the 10 tanks in Group C were confirmed to meet the discharge standards on Sept 21, and the discharge started on Oct 5.

The sampling of the nuclear wastewater stored in Group A tanks for the third round of discharge was completed on July 10. The analysis results showed that they contained trace amounts of carbon-14, cobalt 60, strontium-90, iodine-129 and cesium-137, of which strontium-90 was not detected in the second round of discharge from Oct 5, according to reports released on Thursday by TEPCO.

TEPCO claims that its ALPS facility, a multi-nuclide removal system, can remove 62 radioactive substances except tritium, but it was found that about 70 percent of the water in the storage tanks contained non-tritium radionuclides at a concentration exceeding the regulatory standards applicable for discharge into the environment. #nuclear #antinuclear #nuclearfree #NoNukes

Deadly radioactive dust

In the case of Semipalatinsk, the former Soviet Union’s nuclear testing grounds, the exposure was due to the passage of radioactive clouds. The area and the people were exposed gradually not only during the passage of the cloud but also from the subsequent contamination of the area.

  by beyondnuclearinternational  https://beyondnuclearinternational.org/2023/10/15/deadly-dust/

A look at the studies of professor Masaharu Hoshi. From Impact

The risks of radiation exposure are better understood today thanks to researchers dedicated to working with the victims of exposure, understanding their symptoms, identifying treatments and developing safety protocols. This article looks at the work of one such researcher, Dr. Masaharu Hoshi.

Harnessing atomic particles and radiation led to powerful and world changing technologies. The field of medical imaging has saved countless lives and continues to push the boundaries of medical interventions and research, which would have been impossible without the first x-ray machines. Unfortunately, not all inventions have been so altruistic. 

The advent of nuclear weapons showed the world the destructive potential possible via scientific inquiry. While the dangerous effects of radiation exposure were documented from the inception of this technology, catastrophic events like the bombing of Hiroshima and Nagasaki and nuclear disasters at Chernobyl, Semipalatinsk or Fukushima provide a real-time glimpse into the long-term effects of exposure. 

Investigating the causes of this exposure in order to prevent future accidents is essential, but so too is cataloguing the rates and types of exposure among the victims. With this information, correlations between exposure and health effects, both short- and long-term, can be assessed. This data is crucial for understanding the mechanisms behind radiation effects on living creatures and in assessing risks, safety protocols and treatment. Since the 1980s, Dr Masaharu Hoshi, Professor Emeritus at Hiroshima University, has been traveling around the world, visiting the sites of nuclear disasters in an effort to fully comprehend the risks. In doing so he is also revealing that there is still much we need to learn regarding the effects of radiation exposure. 

Quantifying the risks

“I started my research with the people exposed to radiation in Hiroshima and Nagasaki in the year 1980,” says Hoshi. “Before that I completed my dissertation on nuclear physics with a specialty in radiation measurement.” This graduate training positioned him to become an expert on the effects of radiation. 

The work that commenced in Hiroshima and Nagasaki right after the blast showed that with higher doses of radiation, the greater the effect on the human body, in the form of symptoms like carcinogenesis. The ratio between exposure and effects is termed risk. This measure of risk is useful in treating people exposed to radiation and it can quantify how much risk individuals face depending on the dose of exposure.

“I started my research with the people exposed to radiation in Hiroshima and Nagasaki in the year 1980,” says Hoshi. “Before that I completed my dissertation on nuclear physics with a specialty in radiation measurement.” This graduate training positioned him to become an expert on the effects of radiation. 

The work that commenced in Hiroshima and Nagasaki right after the blast showed that with higher doses of radiation, the greater the effect on the human body, in the form of symptoms like carcinogenesis. The ratio between exposure and effects is termed risk. This measure of risk is useful in treating people exposed to radiation and it can quantify how much risk individuals face depending on the dose of exposure. 

“This work can inform us whether a medical check-up is required every two years depending on the degree of exposure, or if hospitalization is necessary if there has been too much exposure,” explains Hoshi.

He says that the work done in Japan has informed laws regarding radiation exposure safety and protocols in countries around the world, but this is only one scenario in which a person can come into contact with the deadly rays. 

“The people exposed to radiation in Hiroshima and Nagasaki from the atomic bomb were exposed to gamma rays, including a few neutrons, in a short instant,” outlines Hoshi. “From 1 microsecond to about 1 minute which is quite different from the gradual exposure of actual workers in the radiation industry.”

In the case of Semipalatinsk, the former Soviet Union’s nuclear testing grounds, the exposure was due to the passage of radioactive clouds. The area and the people were exposed gradually not only during the passage of the cloud but also from the subsequent contamination of the area. “Therefore, the risk is considered to be different from that of the atomic bomb survivors of Hiroshima and Nagasaki,” confirms Hoshi. 

“Because of that, we started our study on the radiation dose and the health effects occurring in Semipalatinsk, which has been going on since 1994.”

Over the course of these studies over decades he has worked with colleagues to amass databases of over 300,000 cases of exposure and long-term follow-up. It was among these cases, spread out in different locations, that a pattern emerged, revealing yet another variable to consider during an exposure event, being radioactive microparticles. 

Radiation detectives

Initially in Japan, research started on people who came to the area right after the explosion to help their families and were not the direct victims of the bombing. For these individuals the calculated radiation exposure dose was less than 10 mSv which, according to Hoshi, is usually not a problem. 

“Using the Hiroshima University database of people who were exposed to the bombing incident, we found that the mortality rate was higher for those who came to the vicinity directly after the explosion and the cause for this was unknown,” he states. 

Furthermore, Hoshi began to see a similar pattern of exposure and symptoms in other places. In Semipalatinsk it was called Kainal Syndrome and again there was no explanation. Many of the survivors of Chernobyl, Gulf War and Hiroshima Nagasaki who entered after the bombing also suffered from hair loss, severe malaise, which can lead to an inability to work, bleeding, diarrhea and more. 

“It was then that I understood I would have to use epidemiological ideas to uncover what all of these victims had in common,” he says. Eventually, he realised that commonality was radioactive dust.

Hoshi and his team began investigating the potential for radioactive microparticles to cause internal exposure in all organs of the rats, especially in the lung. They found the effects are 20 times more dangerous than usual external exposure according to the animal experiments. 

“With regards to the effects of radioactive particles, some experts have previously pointed it out,” says Hoshi. “However, since there was no supporting research, it has been ignored by public institutions.” 

The effects of radiation exposure are the same for every person on the planet, no one country or group of people are immune. Furthermore, when disaster strikes it is usually not contained to one spot. Contamination of air and water can spread over vast distances, bringing with them their deadly side effects. Hoshi and his collaborators are acutely aware of this and are working hard to share their data as far and as wide as possible. 

Furthermore, Hoshi stresses that due to the need for a variety of expertise, collaboration is absolutely essential. 

“For example, these results are not possible without the input from reactor physicists, radiation and medical physicists, epidemiologists, thyroid specialists, pathologists, medical doctors, as well as statistics and computer database experts,” he highlights. 

Hoshi is grateful for all of the hard work this diverse group has done and will continue to do for the benefit of victims and potential victims. Along with further research on progressive treatment and protection, Hoshi plans to continually develop this field. Their work will carry on studying the effects of radioactive dust and ways to protect against it as well as tackling the big problem of evaluating dose exposure from radioactive dust.

Abstract

High doses of ionizing radiation can cause cardiovascular diseases (CVDs); however, the effects of <100 mGy radiation on CVD remain underreported. Endothelial cells (ECs) play major roles in cardiovascular health and disease, and their function is reduced by stimuli such as chronic disease, metabolic disorders, and smoking. However, whether exposure to low-dose radiation results in the disruption of similar molecular mechanisms in ECs under diabetic and non-diabetic states remains largely unknown; we aimed to address this gap in knowledge through the molecular and functional characterization of primary human aortic endothelial cells (HAECs) derived from patients with type 2 diabetes (T2D-HAECs) and normal HAECs in response to low-dose radiation. To address these limitations, we performed RNA sequencing on HAECs and T2D-HAECs following exposure to 100 mGy of ionizing radiation and examined the transcriptome changes associated with the low-dose radiation. Compared with that in the non-irradiation group, low-dose irradiation induced 243 differentially expressed genes (DEGs) (133 down-regulated and 110 up-regulated) in HAECs and 378 DEGs (195 down-regulated and 183 up-regulated) in T2D-HAECs. We also discovered a significant association between the DEGs and the interferon (IFN)-I signaling pathway, which is associated with CVD by Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis, protein–protein network analysis, and module analysis. Our findings demonstrate the potential impact of low-dose radiation on EC functions that are related to the risk of CVD.

Important new BMJ article increases our perception of radiation risks

September 3, 2023

The BMJ article which was published on Aug 16, 2023 (accessible free of charge) is the result of a lengthy occupational study by US Professor David Richardson and a team of 11 academics and public health researchers in the US, UK, France and Spain. https://www.bmj.com/content/382/bmj-2022-074520

Its conclusion states

“This major update to INWORKS provides a direct estimate of the association     between protracted low dose exposure to ionising radiation and solid cancer  mortality based on some of the world’s most informative cohorts of radiation  workers. The summary estimate of excess relative rate solid cancer mortality per Gy is larger than estimates currently informing radiation protection, and some evidence suggests a steeper slope for the dose-response association in the low dose range than over the full dose range. These results can help to strengthen radiation               protection, especially for low dose exposures that are of primary interest in  contemporary medical, occupational, and environmental settings.”

In a nutshell, the article’s findings

  1. substantially increase our perception of radiogenic risks
  2. confirm that the linear no threshold model for radiation risks is acceptable
  3. give new hard evidence of increased risks at low levels of exposure
  4. act to question the continued use of the LSS studies of Japanese bomb survivors in deriving absolute radiation risks for the public
  5. act to question the ICRP’s continued use of DDREFs which at present halve radiation risks, and
  6. act to put pressure on ICRP, WHO, IAEA, etc to revise upwards the current low risks of radiation.

DISCUSSION

  1. Numerical Risk of Radiation…………………………………………………………………………………………………..So it can be shown that the INWORKS study increases the currently perceived absolute risk of fatal cancer in the UK from ~ 5% to 13% per Sv. This is a substantial increase and will need to be addressed by the ICRP and national authorities.
  2. 2. Strengthens and Increases the risks found older studies. Second, the new study strengthens an earlier 2018 study (Richardson et al, 2018) by the same team by adding another 10 years’ data to the epidemiology datasets used in the metastudy. It not only strengthens the findings but actually increases the observed ERR risk by ~10% ie from 0.47 to 0.52 per Gy.
  3. 3. Increased Risks at Low Doses. Perhaps most significant, are the study’s findings of higher risks at very low doses between 0 and 150 mGy which are the doses we need to be concerned with………………………………………………………………………………………………………………………………………more https://www.ianfairlie.org/news/important-new-bmj-article-increases-our-perception-of-radiation-risks/?fbclid=IwAR0TtpWfyxm1ebiaHGw_eUJd1n1PWRfkmGF3n-YtBnO0rMIRi2XqcPzYYWY

We are all Hibakusha- the global footprint of nuclear fallout

By M.V. Ramana  https://beyondnuclearinternational.org/2023/09/03/we-are-all-hibakusha/

The front page of the Times of India of August 7, 1945, carried the headline World’s deadliest bomb hits Japan: Carries blast power of 20,000 tons of TNT. For millions around the world, headlines of that sort would have been their first intimation of the process of nuclear fission on a large scale.

But, a careful stratigrapher, who studies layers in the soil or rock, might be able to discern that, in fact, nuclear fission had occurred in July 1945. The stratigrapher would just have to look for plutonium at Crawford Lake in Ontario, Canada, the site proposed as the “golden spike” spot to mark the start of the Anthropocene (recognising the problems with its definition as highlighted in Down To Earth’s interview with Amitav Ghosh).

What happened in July 1945 was, of course, Trinity, the world’s first nuclear weapon test, now familiar to many through the film Oppenheimer. A group of researchers recently reconstructed how the plutonium released during that explosion would have been transported by the wind. They calculated that direct radioactive fallout from that test would have reached Crawford Lake within four days of the test, “on July 20, 1945 before peaking on July 22, 1945”.

Since Crawford Lake is nearly 3,000 kilometres from the Trinity test site in New Mexico, it stands to reason that many other places would also have received radioactive fallout from the Trinity test. Now consider the fact that there have been at least 528 nuclear weapon tests around the world that took place above the ground, plus the bombs dropped on Hiroshima and Nagasaki—and you can easily imagine how radioactive fallout must have fallen practically everywhere, whether on land or in the oceans.

Not included in the abovementioned list of 528 is the debated 1979 “Vela incident” that most likely involved an Israeli nuclear weapon test with help from South Africa. It is described as debated only because political elites in the United States, whose Vela satellite 6911 detected a double-flash of light that is characteristic of nuclear explosions, did not want to impose sanctions on Israel.

In 2018, two scientists collected a range of evidence consistent with such a nuclear test, importantly cases of radioactive element iodine-131 that was found in the thyroids of some sheep in 1979—in the south east part of Australia, across the oceans. Again, proof that radioactive fallout from nuclear weapon tests spread out globally.

But it is not just nuclear weapons tests. Accidents at nuclear power plants, too, have produced radioactive fallout that has contaminated the peoples of the world. Radioactive cesium released by the 1986 Chernobyl reactor explosion was found in multiple countries across Western Europe. Yet again, sheep, this time in England, Scotland and Wales, were contaminated, and for a time scientists could not even understand the behaviour of the radioactive cesium that the sheep were ingesting.

The sheep remained contaminated for decades. Restrictions on sheep were lifted in all areas only in 2012. Of course, closer to Chernobyl, many areas are still highly contaminated. Radiation levels go up and down depending on outside events, such as forest fires or the Russian army invading the area.

Even without nuclear weapons explosions and reactor accidents, people around the world are exposed to radioactive materials—from reprocessing plants. These facilities chemically process the irradiated spent fuel from nuclear power plants, while also producing very large volumes of liquid and gaseous radioactive effluents. These effluents are released into the air; exposure to these constitutes the largest component of the radiation dose to “members of the public from radionuclides released in effluents from the nuclear fuel cycle”.

People in South Asia have, of course, been exposed to radioactive fallout from nuclear explosions conducted by other countries, nuclear reactor accidents, and reprocessing plants. What about the nuclear weapons exploded by India and Pakistan in 1998, and by India, in 1974? All of these weapons were exploded underground, which should, in principle, have contained all the radioactive materials within the soil. If so, their route for exposing people to radiation can only be by contaminating underground water sources, sometime in the future.

But underground nuclear weapon tests do, sometimes, vent, releasing radioactive materials into the air. After the Limited Test Ban Treaty of 1963, all US nuclear weapons tests were designed to completely contain the radioactivity underground. Nevertheless, 105 of them vented radioactive materials into the atmosphere. A further 287 tests had “operational releases” whereby radioactivity was released during routine post-test activities. Similarly, several hundred underground nuclear weapons explosions at the Novaya Zemlya test site in the Soviet Union released radioactivity into the atmosphere.

Radioactive materials from these releases spread far and wide. In 1970, radioactive materials vented during the Baneberry test were detected as far as Canada; but Canadian diplomats told US officials that “they had no intention to make a formal protest or to conceive of the event as a violation” of the Limited Test Ban Treaty.

It is possible, though not very probable, that the 1998 or the 1974 nuclear tests vented radioactivity. One reason to suspect venting is that residents of the villages near Pokhran, India have repeatedly complained of different kinds of physical illnesses, and demanded that radiation levels be checked. So far, no comprehensive and independent examination of the health of these people or the radioactivity levels in the area has been conducted.

Nearly eight decades since the nuclear age started, people around the world, not to mention the flora and fauna, have all been exposed to radioactive materials from nuclear activities. Any exposure to radioactivity elevates the risk of developing cancer or cardiovascular disease, two great health scourges in modern times.

We are all, in the words of Robert “Bo” Jacobs, the “Global Hibakusha”, survivors of the nuclear age but always at risk of developing one of the diseases associated with radiation exposure. And the worldwide spread of fallout is not, as Jacobs points out, “something that happened, it is something that is still happening”.
