America is unprepared for medical consequences of a nuclear attack

U.S. not medically prepared for nuclear threats, http://www.thegazette.com/subject/opinion/guest-columnist/us-not-medically-prepared-for-nuclear-threats-20180128  Alan Moy, 28 Jan 18

 The recent false alarm in Hawaii underscores the threat from nuclear devices. While there has been media attention placed on how the United States is taking military and diplomatic action against North Korea from launching a nuclear strike, there is little media attention given to how well the United States is medically prepared for a nuclear attack. According to a recent report in the Bulletin of the Atomic Scientists, U.S. cities are not medically prepared for a nuclear detonation. This report, written by Dr. Jerome Hauer, who was the former assistant secretary for the Office of Public Health Emergency Preparedness at the U.S. Department of Health and Human Services, asserts that the United States is completely unprepared to manage the aftermath of a nuclear detonation. We are at a moment in history where nuclear terrorism is an unfortunate reality. North Korea and Iran have established nuclear capabilities, and Pakistan has stockpiles of highly enriched uranium.

These countries have a history of supporting terrorist groups. It has been acknowledged by our government that highly enriched uranium can be smuggled into this country to build a 10-kiliton improvised nuclear bomb, like that dropped on Hiroshima in 1945. A nuclear threat would even include a dirty bomb that combines a conventional explosive with radioactive isotopes, which could contaminate an area and leave a residual radioactive “hot zone” that is too dangerous for even first responders to enter. Also, radioactive particles can disperse into the air and create a “plume” that could extend hundreds of miles away from ground zero and create a contamination area that would last for years.

A nuclear blast would instantly release a massive pressure wave and heat that would incinerate everything within half a mile and kill an estimated 75,000 to 100,000 people. Another 100,000 to 200,000 would suffer complexed radiation burns, while others would be exposed to high doses of radiation that would cause acute radiation syndrome that is characterized by bone marrow failure and gastrointestinal, cardiac, neurological and pulmonary toxicity. The starkest fact about a nuclear bomb attack is that it destroys the capacity to respond from a medical and civil service perspective. There will be a loss of local government services from firefighters, police and hospitals, along with loss of water, sewage and utilities. There will be a loss of communication systems to direct survivors where to evacuate for treatment.

The management of mass casualties from nuclear detonation is far more complex than for natural disasters. Hot zones are too dangerous for first responders to enter to render medical assistance to casualties. Yet, victims would still need to be evacuated somehow. According to the report, most U.S. cities lack medical preparedness to manage the aftermath of a nuclear explosion. FEMA has not devoted enough attention to address this issue. This makes it important for cities and states to develop plans for the worse case scenarios. Each state should have a plan of preparedness that includes special medical triage centers; coordinated schemes from state military and local police to provide mobile communication assets and protection against civil unrest; and specialized trained hospitals that can medical manage the injuries associated with a nuclear bomb. There needs to be a statewide plan from the governor’s office from each state, along with each state’s department of public health, to ensure there is sufficient medical preparedness.

Several government officials stated they were unable to take steps forward out of being accused of inciting fearmongering. However, developing a comprehensive preparedness program against nuclear threats should not just stop with military action but should include a medical preparation program regardless of how politically undesirable the subject may be. Preparedness should be mandated at every local and state government level.

High incidence of birth deformities in Pacific communities exposed to French nuclear bomb testing

French overseas minister open to nuclear study https://www.onepng.com/2018/01/french-overseas-minister-open-to.html, 1/26/2018   The French overseas minister says she is not opposed to calls for a study into the possible genetic consequences of the French nuclear weapons tests in French Polynesia.

Annick Girardin has told journalists in Tahiti that there will be an answer to the recently raised calls for such a study.Last week, a child psychiatrist, who had worked in French Polynesia for years, suggested that an independent investigation be carried out after noticing a high incidence of disturbed and deformed children among the off-spring of people exposed to radiation from the atmospheric tests.

Girardin has acknowledged the concerns, saying it has to be established how to deal with the question and to see if it is possible to work on it with other countries.

The minister has restated that the former president Francois Hollande recognised two years ago in Papeete the French legacy and assumed responsibility.

She has also launched a project in Papeete to build an institute of archives and documents related to the tests.
She has also frozen the sale of land in the city previously used by the navy for its command for it to be able to be used for a memorial site.The head of the nuclear test veteran’s organisation Roland Oldham is dismissive, saying this will only see the light of day once people are dead.

He has continued to urge Paris to compensate the nuclear test victims suffering from poor health.

Until 2009, France claimed its weapons tests were clean but then passed a law accepting compensation demands.

Hundreds of applications have been filed since but almost all have been thrown out.

Workers demolishing Hanford’s Plutonium Finishing Plant still vulnerable to airborne radiation

Hanford radioactive monitoring not protecting workers, By Annette Cary, Tri-City Herald,  January 25, 2018 New test results show that monitoring for airborne radioactive contamination has not protected Hanford nuclear reservation workers as the site’s highly contaminated Plutonium Finishing Plant is demolished.

Two more Hanford workers have inhaled or ingested small amounts of airborne radioactive material, with tests for 180 workers still pending, according to the Department of Energy.

The most recent results were for the first 91 workers who requested testing after a spread of radioactive material was discovered in mid-December.

In addition, air samples collected and analyzed at sites outside the demolition zone around the plant show that airborne radioactive contamination was not found in 2017 by other monitoring methods meant to more quickly warn of a potential danger to workers.

A memo with the latest results for both checks for radioactive contamination of workers and for air monitoring results was sent to Hanford workers Wednesday afternoon by Doug Shoop, manager of the DOE Hanford Richland Operations Office.

In one case, airborne contamination that appeared to be linked to demolition of the plant was found about 10 miles away, near the K Reactors along the Columbia River, workers were told. The finding follows an earlier discovery of airborne contamination in June at the Rattlesnake Barricade, a secure entrance to Hanford just off public Highway 240…….. http://www.columbian.com/news/2018/jan/25/hanford-radioactive-monitoring-not-protecting-workers/

Victims of Fukushima nuclear radiation, on both sides of the Pacific

Fukushima heroes on both sides of the Pacific still fighting effects of radiation, stress and guilt, Following the catastrophic earthquake and tsunami of 2011, selfless Japanese workers battled nuclear-reactor meltdown, and thousands of US troops provided disaster relief. Today, many are counting the cost to their mental and physical health, SCMP, BY ROB GILHOOLY, 25 JAN 2018 Christmas Day saw dozens of masked men descend on Futaba, in the northeast of Japan’s main island of Honshu. They moved deliberately along deserted streets, clearing triffid-like undergrowth and preparing to demolish derelict buildings. Their arrival marked the beginning of an estimated four-year government-led project to clean up Futaba, which has succumbed to nature since its residents deserted almost seven years ago.

Futaba is one of two towns (the other being neighbouring Okuma) on which sits the 350-hectare Fukushima Daiichi Nuclear Power Plant, which experienced multiple reactor meltdowns and explosions in March 2011, contaminating huge swathes of land and forcing the evacuation of 160,000 residents – all the result of the magnitude-nine undersea Tohoku earthquake and the devastating mega-tsunami that hit on March 11, claiming up to 21,000 lives.

Despite 96 per cent of Futaba still being officially designated as uninhabitable due to high radiation levels, the government has set spring 2022 as the return date for its 6,000 or so residents. That the government has also built a 1,600-hectare facility to store up to 22 million cubic metres of nuclear waste in the town has led to doubts that many will return.

I find it difficult to believe anyone would want to go back,” says Ryuta Idogawa, 33, a former employee at Fukushima Daiichi operator Tokyo Electric Power Co (Tepco), and one of the so-called “Fukushima 50” – a hardcore of station workers who remained on-site after 750 others had been evacuated, battling to bring the melting reactors under control at great risk to their own safety.

“They say time heals,” Idogawa adds, “but that depends how deep the wounds are.”

On the other side of the world, members of a different and larger group of people than the Fukushima 50 are suffering health problems, ostensibly as a result of the disaster. For more than seven weeks following the catastrophe, the United States mounted a massive disaster relief mission, dubbed Operation Tomodachi (the Japanese word means “friend”). The initiative directly or indirectly involved 24,000 US service personnel, 189 aircraft and 24 naval ships, at a total cost US$90 million.

While the mission was lauded a success by the US and Japanese governments, during Operation Tomodachi, thousands of US sailors were inadvertently exposed to a plume of radiation that passed over their ships, which were anchored off the Pacific coast of Japan. Since then, several hundred have developed life-changing illnesses, such as degenerative diseases, tumours and leukaemia, and defects have been detected in foetuses of some pregnant women. All are a result, they claim, of being irradiated by the plume.

According to one report, 24 sailors, who were in their late teens or 20s at the time, are living with a variety of cancers. At least six have died since 2011, while others suffer post-traumatic stress disorder (PTSD).

“Unlike the nuclear plant workers, these sailors had no protective clothing, in fact some of them literally had no shirts on their backs because they had given all their clothing away to people they saved from the tsunami waves,” says Charles Bonner, a lawyer at one of three law offices representing 402 sailors who have filed a US$5 billion lawsuit against Tepco and General Electric Co, a suit that has been given the go-ahead to be heard in a US federal court. (Fukushima Daiichi’s Reactor No. 1 – the plant’s oldest reactor – was built by American manufacturer General Electric Co.)

“And because they had given away all their bottled water to tsunami survivors, they were drinking desalinated water that also had been contaminated,” Bonner continues. “I do not doubt the psychological impact of the disasters on the plant workers, but at least they had masks and protective clothing, as required by law. The sailors, however, knew nothing of their exposure and were literally marinated in the radiation.”……….

lawyer Bonner says that while his team represents more than 400 sailors, there were a further 69,600 American citizens – military and civilian – potentially affected by the radiation, and who have yet to join the class lawsuit.

He also expresses indignation at the Royal Society study and the viewpoint of cancer expert Thomas, insisting that the health of the young US service men and women aboard the ships was endangered and in many cases compromised by Operation Tomodachi. “[The sailors] were certified by the Navy as healthy and fit, so why are they getting cancer and other illnesses?” he asks. “That can only be because they were exposed to radiation. It can’t just be a coincidence.”…….. http://www.scmp.com/magazines/post-magazine/long-reads/article/2130359/fukushima-heroes-both-sides-pacific-still

Space travel damages astronauts’eyes

How does space travel affect the eye? Astronauts’ retinal nerves found damaged after months in orbit http://www.ibtimes.co.uk/how-does-space-travel-affect-eye-astronauts-retinal-nerves-found-damaged-after-months-orbit-1656000

The finding comes as Nasa continues to prepare for missions to Mars and beyond. By Shubham Sharma, As Nasa continues to prepare for manned deep-space missions to Mars and beyond, a new study has highlighted a major concern for the agency – the affect of long-term space travel on astronauts’ retinal nerves, which ultimately degrades their ability to see.Nearly 50% of astronauts report cases of vision impairment after spending a prolonged time in space, sometimes months or maybe years after returning to Earth. The cases vary from person to person but the new study, published in the journal JAMA Ophthalmology and reported by Live Science, factors something that could be the key trigger for these problems.

After studying pre- and post-flight optical scans of 15 astronauts who had spent around six months in space, researchers noted a significant change in their optic nerves, the delicate transmitter that takes visual information from the retina to the vision centres of the brain, helping a person register what they see.

As per the report, the analysis of Bruch membrane openings, the gaps at the back of the eyeball through which these nerves travel, revealed that their delicate tissues were significantly swollen and warped.

The critical damage was noted weeks after the astronauts’ return to Earth and has been touted as the first direct observational evidence that highlights the critical effect of long-term space travel on optic nerves. Some of the study subjects already had vision-related problems but the patterns in the deformity could not be ignored.

Though the actual cause of this condition remains unknown, the researchers believe it could be due to the difference between normal and cosmic pressures. According to them, when astronauts reach space, the pressure increases and the eyes take their time to adjust to that change. However, when they come back to Earth, the pressure goes down suddenly, which the eyes fail to deal with.

As of now, it cannot be said for certain if this is the exact reason, but whatever it may be, Nasa will have to study this problem carefully before going ahead with its deep-space missions. The success of any manned program, whether to the Moon, Mars or any other distant planet, will depend on astronauts and how they react to changes in their surroundings several thousand kilometres away from Earth.

Long-Term Exposure to Low-Dose Radiation and Cancer: Dr. David Richardson at the Hiroshima Peace Institute (EN & JP)

 

The initiation of the Manhattan project in 1943 marked the emergence of the discipline of health physics and an expansion of research on the health effects of ionizing radiation. The health effects of occupational exposure to radiation were viewed from different perspectives by different members of the Atomic Energy Commission (AEC). There were those with immediate concerns and a focus on issues related to wartime production and health effects which were definite biological changes which are immediately evident or are of prognostic importance to health. Others had an interest in a more general understanding the effects of radiation on human health, including long term and genetic consequences. There were also managerial concerns, which persist today; Stafford Warren, medical director of the program, encouraged health research to help strengthen the government’s interest in case of lawsuits or demands for workers’ compensation. These concerns motivated a large scale epidemiological program of research on nuclear workers. Beginning in the mid-1980’s, numerous publications on cancer among workers at nuclear facilities appeared, mostly in the US and UK. Risk estimates from individual studies were uncertain, with wide confidence intervals; and, positive associations between radiation and cancer were observed in some, but not all cohorts. To summarize results across studies and improve statistical precision, pooling projects were undertaken. This lecture reviews the history of these pooled studies and then presents results from the most recent, largest, and most informative of these analyses, known as INWORKS. This is a combined study of 308,297 nuclear workers from the United Kingdom, France, and the United States of America. Quantitative results are presented and the strengths and limitations of INWORKS are discussed. (Lecture at Hiroshima Peace Institute, 30 November 2017)

North Korean people have good reason to hate the American government

Why Do North Koreans Hate The American Government,    http://www.ronpaullibertyreport.com/archives/why-do-north-koreans-hate-the-american-governmentBy Liberty Report Staff,5 May 2017

Did you stop for a second and ask yourself why the North Koreans hate the American government?
Could it (maybe) be that the North Koreans hate the American government’s foreign policy?

​The Intercept has provided some startling facts about America’s terrible unconstitutional entry into a foreign Civil War on the other side of the globe in 1950:

How many Americans, for example, are aware of the fact that U.S. planes dropped on the Korean peninsula more bombs — 635,000 tons — and napalm — 32,557 tons — than during the entire Pacific campaign against the Japanese during World War II?

How many Americans know that “over a period of three years or so,” to quote Air Force Gen. Curtis LeMay, head of the Strategic Air Command during the Korean War, “we killed off … 20 percent of the population”?

Twenty. Percent. For a point of comparison, the Nazis exterminated 20 percent of Poland’s pre-World War II population. According to LeMay, “We went over there and fought the war and eventually burned down every town in North Korea.”

Every. Town. More than 3 million civilians are believed to have been killed in the fighting, the vast majority of them in the north.

How many Americans are familiar with the statements of Secretary of State Dean Rusk or Supreme Court Justice William O. Douglas? Rusk, who was a State Department official in charge of Far Eastern affairs during the Korean War, would later admit that the United States bombed “every brick that was standing on top of another, everything that moved.” American pilots, he noted, “were just bombing the heck out of North Korea.”

Douglas visited Korea in the summer of 1952 and was stunned by the “misery, disease, pain and suffering, starvation” that had been “compounded” by air strikes. U.S. warplanes, having run out of military targets, had bombed farms, dams, factories, and hospitals. “I had seen the war-battered cities of Europe,” the Supreme Court justice confessed, “but I had not seen devastation until I had seen Korea.”

How many Americans have ever come across Gen. Douglas MacArthur’s unhinged plan to win the war against North Korea in just 10 days? MacArthur, who led the United Nations Command during the conflict, wanted to drop “between 30 and 50 atomic bombs … strung across the neck of Manchuria” that would have “spread behind us … a belt of radioactive cobalt.”

Oh there’s more…

The Bioaccumulation of contamination in plankton

Capture du 2018-01-18 12-01-02.png

 

Quote (emphasis added) “Page 59. The problem of radioactive particles falling into the ocean raises the question of their availability to this portion of the biosphere. Plankton normally found in sea water are consumed in large quantities by fish.
 
These plankton concentrate mineral elements from the water, and it has been found that radioactivity may be concentrated (Page 60) in this manner by as much as a thousand fold. Thus, for example, one gram of plankton could contain a thousand times as much radioactivity as a gram of water adjacent to it. The radioactivity from these plankton which form a portion of fish diet tends to concentrate in the liver of the fish, and, if sufficiently high levels of contamination are encountered, could have a marked effect upon the ecology of an ocean area.

Atomic batteries, including plutonium pacemakers – not monitored

Paul Waldon, 12 Jan 18  The 1970’s gave birth to Atomic Batteries, used in buoys, remote radio stations and for decades gifted to heart patients with pacemakers. With a half life of 87.7 years this issue has been described as problematic when the patients eventually die. Neither the United States nor the Soviet Union- the two countries where the devices were implanted- were particularly diligent about documentation, many of the pacemaker recipients and their 200 milligram plutonium batteries simply disappeared.

How the science of radiation protection was subverted to protect nuclear bombs and nuclear power

 

From Richard Bramhall

Low Level Radiation Campaign

This article was originally written for Radioactive Times in 2008. I didn’t set out to write the whole history of radiation protection – just to highlight the turning point when the bogus concept of absorbed dose was foisted on the world.

The nonsense of Absorbed Dose

Absorbed doses of ionising radiation are defined as an average of the energy that is transferred into large volumes of body tissue. This approach is valid for considering external exposures, like X-rays or natural gamma (cosmic rays) but not for situations where radioactive substances inside the body irradiate microscopic volume of tissue selectively. Particles of Uranium and Plutonium are examples; the range of their alpha emissions is so tiny that all the energy is concentrated into a few hundred cells. Some call this kind of situation “pinpoint radiation”. Using absorbed dose to assess the potential health damage is like a doctor examining a child whose skin is covered with small red marks.

Now look, Mrs. Smith, I’m a doctor and I’m telling you even if your lodger does stub out his cigarette on little Nelly’s tummy there’s no problem because she absorbs very little energy from it. You give her a far bigger dose when you put in her a nice warm bath.

The trick was pulled in the depths of World War 2, subverting the science of radiation protection in order to protect the Manhattan Project and the A-bomb; it has served to protect the nuclear industry ever since.

Radium autopsies and internal risk standards

Until the 1920s the main focus of radiation protection was external X-rays, but the Radium dial painters’ scandal made it obvious that internal effects needed specific investigation. This led to new standards determined by looking at the actual effects of radium in the dissected tissues of people.

Radium is produced by the radioactive decay of natural Uranium. Its own radioactive decay emits alpha particles. Unlike X-rays and gamma rays, alphas have very little penetrating power so they are only hazardous once they’re inside the body. Even then they don’t travel far but the downside is that all their energy is deposited in a very small volume of cells.

From the earliest years of the 20th century luminous Radium paint was applied to the faces of clocks, watches and compasses to make them glow in the dark. World War 1 boosted demand and through the following decades hundreds of girls and women were employed to paint dials and pointers with various brands of paint – Undark, Luna and Marvelite. They would routinely put the tips of their paint brushes between their lips to obtain a fine point for the trickier numerals. By 1923 it was clear that the Radium they thus ingested was causing dreadful, agonising and frequently fatal illnesses.

Radium mostly lodges in bone, so the diseases affected the blood-forming function of the women’s bone marrow, leading to anaemia. Those with higher body burdens had ulcers and their bones were weakened to the point where vertebrae collapsed and legs would break spontaneously. The first deaths directly attributed to Radium Necrosis came in 1925. The inventor of the Undark brand died like his workers, his bone marrow destroyed and his hands, mouth and jaw bones eaten away. Court cases, compensation payments and improved workplace practices followed (a ban on licking brushes was the first) but for a decade and a half there were no mandatory exposure limits.

By 1941 America was once more tooling up for industrialised warfare and the government was ordering large numbers of luminized instruments. By that time the global total of Radium extracted from the earth’s crust was only 1.5 kilograms but, already, the deaths of more than a hundred people were attributable to its processing and use. Officials insisted that safety standards be devised, including a tolerance limit for internal Radium. A committee of the National Bureau of Standards looked to a post mortem study of Radium dial painters and people who had been exposed to Radium through medical treatments. They saw that there were detectable injuries in all the bodies which contained a total of 1.2 micrograms of Radium but no injuries were discernible in those containing 0.5 micrograms or less. The committee settled on 0.1 micrograms as a cut-off. The history books show they knew this was a highly subjective stab in the dark.

Since Radium decays to Radon gas officials were able to use Radon as an indicator for metering. From then on, Radium workers were required to breathe into an ion chamber which detected the radioactive decays of Radon and its own daughter, Polonium. An immediate change of occupation was recommended as soon as the level indicated that a worker’s body contained more than 0.1 micrograms of Radium.

Plutonium takes centre stage

World War 2 was midwife to the principle of nuclear fission, a completely novel substance – Plutonium – and the possibility of a Plutonium-powered bomb. The Manhattan Project was set up to make Plutonium for the bomb in secret and in near total ignorance of its effects on health. It was known to be an alpha emitter so, for expediency, the standards for Radium were extended to Plutonium, modified by animal experiments comparing the effects of the two substances.

All this – both the Radium standard and the Plutonium standard derived from it – was primitive science which had no way of detecting subtle lesions and cancers which may take decades to appear. The discovery of the double helix structure of DNA was still a decade away and for another 50 years no-one suspected the existence of epigenetic effects (genomic instability and the bystander effect). So the safety standards were unlikely to reflect long-term health effects but they did have the huge philosophical advantage of being rooted in reality; the Radium researchers had followed the essentially scientific principle of looking for a relationship between cause and effect. Maybe this was because they were medical practitioners, campaigners for workers’ rights and newspapers eager for the human interest angle on any story. Maybe their investigation enjoyed some liberty because the dial painting industry was owned privately, rather than by any government, and because at that time the fate of the “free” world did not seem to hang on the outcome.

Exit Medicine, stage left; Enter Health Physics, stage right

By 1944 everything had changed. Plutonium was being produced in significant amounts and any potential it might have to kill its own workforce now affected a top-level policy funded by a bottomless budget with the imperative of building the bomb before Stalin could. More crucially for the scientific principles of radiological safety, physicians were no longer in charge, but physicists.

The agent of change was a British physicist, Herbert Parker, head of radiation protection at the Manhattan Project. His earlier career in British hospitals had made him familiar with X-rays and a kind of therapy that used Radium as an external source, confining it in tubes and placing it carefully to irradiate cancerous tissues. (This medical application had been tried as early as 1904, only six years after Radium was discovered. In marked contrast to the dial painters’ problems, it didn’t involve Radium becoming inextricably mingled with a patient’s bones.) Parker had a physics-based view; radiation was a single phenomenon, whether it came from an X-ray machine or a speck of Plutonium. As with light, where the physicist isn’t too interested in whether the source is a light bulb or the sun, Parker was concerned with how much energy the radiation delivered to the tissue of interest. The language here is of ergs, from the Greek for work. It is defined in dynes, the Greek for force; the units are physical – movement, velocity, grammes of mass, centimetres of length, seconds of time.

Parker was one of the first to call himself a Health Physicist. In his world there was no call for a bedside manner.

The internal/external Switcheroo: Act 1

Using his physicist’s approach, Parker shifted the focus from direct investigation of the effects of specific substances onto a new concept – radiation dose – which he could apply to radiation from any source and all sources, providing a way to assess workers’ total exposure to all the novel nuclides the Manhattan Project was now creating. He defined a unit of dose in ergs per gramme of tissue and called it the Roentgen Equivalent Physical, or rep. Its very name betrays the mindset; Wilhelm Roentgen was the discoverer of X-rays (for a long time they were called Roentgen rays). The source of X-rays is always outside the body, so we can see the understanding of dose, and hence risk, was now to be based on an external paradigm.

The first limit for Plutonium in the body based on Parker’s dose model was set at 0.01 reps per day, a quantity which exactly matched the energy deposition from the old tolerance limit of 0.1 microgramme of Radium. No change there then. What did change was that instead of the empirical scientific inquiry based on actual tissue damage and instead of the tentative subjectivity of the 1941 Standards Bureau Committee’s decision on a Radium level, the new model gave an impression of mathematical precision, certainty and universal applicability. This was the new, square-jawed and confident nuclear era where bombs of unimaginable power would biff the Red Menace into oblivion and unlimited atomic energy would fuel everything in a world of peace and plenty.

Internal/external Switcheroo: Act 2

Any risk model needs two types of data – for exposure and for effect. Unfortunately, there were no reliable data even for X-rays despite 50 years’ experience. There was too much variability in the machines and the conditions in which they were used; doses were largely unknowable and many of the long-term effects had yet to emerge. But after 1945 the surviving people of Hiroshima and Nagasaki provided the authorities with a fresh opportunity. Funded and controlled by America, data on the survivors’ health was gathered (as it still is) in what have become known as the Life Span Studies or LSS.

A full analysis of the flaws in the LSS is beyond me. As far as studying internal radioactivity is concerned the flaw is fatal; the control population providing the base-line of expected rates of disease, to be compared with disease in the exposed population, was recruited from the bombed cities themselves – they had either been outside the city when the bomb fell, or in some other way were shielded from the flash of the explosion. The “exposed” population consisted of people who had been in the open and so received a large dose of external gamma rays. But both groups ingested and inhaled just as much fallout as each other, so the LSS are totally silent on internal radiation. The only difference between them was the external irradiation. LSS nevertheless is the basis of radiation protection standards all over the world to this day for both external and internal.

Internal/external Switcheroo: Act 3

The LSS were not begun until 1950 (another flaw, obviously, because by then many of the most susceptible people had died) but already, in 1948, America’s Atomic Energy Commission had pressed the National Council for Radiation Protection (NCRP) to develop safety standards for the growing nuclear industry. An especial concern was the quantity of novel elements which, being alpha emitters, would present internal hazards. Separate sub-committees addressed internal and external radiation. The external sub-committee completed its work quite quickly but the other was slowed down by the many complexities of internal contamination. The problem is that physicists don’t have much clue about where radioactive elements go once they are inside the body, how long they stay there or what biological damage they’re doing. Impatient with the delays, NCRP’s Executive closed down the internal committee in 1951 and stretched the report of the external committee to cover internal radiation. Karl Z. Morgan, chair of the internal radioactivity sub-committee, refused to agree that internal could be dealt with like external. For the rest of his life he was a critic of official radiological protection bodies –

I feel like a father who is ashamed of his children.

Internal/external Switcheroo: Act 4

In 1950, American influence revived the International X-ray and Radium Protection Committee (IXRPC), which had been dormant during the war. In fact only two of its members were still alive and one of those was an American who was Chairman of the American NCRP. But needs must, and an international body would probably look more credible than a unilateral American one, so IXRPC was reborn as the International Commission on Radiological Protection (ICRP). In reality ICRP was just an overseas branch of the NCRP and in 1953 it adopted the NCRP report wholesale.

Epilogue

An epilogue is a short speech at the end of a play. In the case of this drama it’s hard to be brief. I’ll give two snapshots – one is global, the other is a family tragedy.

Chernobyl

In 1986 the accident at Chernobyl spread fallout round the whole planet and millions of people inhaled and ingested it. Thousands of published reports from Russia, Belarus, the Ukraine, Greece, Germany, Britain, and even as far west as the Californian coast show a wide range of post-accident health effects not predicted by ICRP’s model. In 2007 ICRP adopted new Recommendations in which there is a single reference to one study of Chernobyl. It’s a paper on thyroid cancer. They cite it for the sole purpose of establishing that it’s so hard to be sure what doses the patients had got from the fallout that the accident can tell us nothing useful. ICRP clings so hard to the dogma of dose that they are willing to rob the human race of the chance to learn about the results of the worst ever reactor accident (I wrote this before Fukushima).

Malcolm Pattinson

This is one among millions of similar stories, but enough detailed information has leaked out to let us learn from it.

In May 2007 The Guardian (linked here or here) and The Times carried reports of a Cumbrian woman’s shock at finding out what had happened to her father 36 years earlier.

Angela Christie’s father, Malcolm Pattinson, died of leukaemia in 1971. He was 36 years old and he worked at Sellafield. Or he had worked there; the Times reported that by the time he died he had been off work for 18 months because his wife feared for his health. As soon as he was dead his employers made frantic efforts to obtain organs and bones from his body. The local coroner, doctors and solicitors were involved but the family was neither consulted nor informed. In 1979, after a long battle during which the employers admitted liability, an out-of-court settlement brought Mr. Pattinson’s widow and daughters compensation payments variously reported as £52000 and £67000.

All this happened when Malcolm’s daughter Angela was in her teens. She grew up and went to work at Sellafield like her father. She married and had three children of her own. Then she read in a newspaper that her father had been one of many men in the industry whose organs had been harvested for radiological research. She asked for the legal papers and received several boxes full.

They’re quite shocking, which may indicate why Mr Pattinson’s employers were so interested in snatching his body parts. His liver contained 673 times as much Plutonium as the average for a sample of Cumbrians who had not worked in the nuclear industry and his lungs had well over 7000 times as much. His liver had 53 times the amount of Plutonium found in the most contaminated of the nuclear workers in other reports and his lungs had 42 times as much. Mr. Pattinson’s body burden was far greater than any other worker data I have seen. I conclude that he had either been involved in an accident or had been working in an unacceptably dirty environment. Either would be a scandal, but the far wider scandal is that the industry and the government would not see even those monstrous levels as a likely cause of his death.

From the data published in the Guardian I calculated the radiation dose Mr. Pattinson received from his body burden of Plutonium. Using the same methods as the ICRP I worked out the annual dose at 26 milliSieverts. That’s about ten times the usual (bogus) yardstick of natural background but it would have been nothing very remarkable in the early 1970s. Even today, when standards are more cautious, employers would still not be breaking the law by exposing a worker to such a dose so long as it wasn’t for more than one year in five.

ICRP’s risk estimates would not predict that a 26mSv dose would cause Mr. Pattinson’s leukaemia, in just the same way as they do not predict the cluster of childhood leukaemia at Seascale, next door to Sellafield — the doses are far too low. According to ICRP, if Mr. Pattinson was going to die of any cancer, the chance that it would be caused by the Plutonium in his body was only 1.3 in a 1000.

To the person in the street the idea that fatal leukaemia in a young man is 770 times more likely to be caused by bad luck, bad genes, bad diet, smoking, a virus or an act of God than by the acts of an employer who contaminated him heavily with a bone-seeking, alpha-emitting radionuclide may seem insane. It is insane. It is insane in the way Dr. Strangelove was insane; the logic is impeccable but the theoretical premises are wrong. The good news is that growing numbers of scientists are recognising that ICRP is in error. These include Jack Valentin, the man who recently retired as ICRP’s Scientific Secretary.

Radiation Dose Is Meaningless

Dose is meaningless.jpg

 

In other words, where hot or warm particles or Plutonium or Uranium are located in body tissue or where sequentially decaying radionuclides like Strontium 90 are organically bound (e.g. to DNA) “dose” means nothing.
This is massively significant. Official radiation risk agencies universally quantify risk in terms of dose. If it means nothing the agencies know nothing and can give no valid advice.
Their public reassurances fall to the ground. They can no longer compare nuclear industry discharges with the 2 millisieverts we get every year from natural radiation, or the cosmic rays you’d receive flying to Tenerife for a holiday.

Dose is meaningless
… emerging consensus
[This page from November 2006 is now updated with this new link to extracts from ICRP Publication 103 (the 2007 Recommendations) but its content otherwise remains unchanged. At the foot there is recent material on ICRP’s position.] http://www.llrc.org/llrc/wobblyscience/subtopic/dosemeaningless4.htm
The 2005 Recommendations of the International Commission on Radiological Protection: Draft for Consultation were published in late 2004. The final version has not been published at the date of writing (early November 2006) and ICRP tells us publication has in fact been set back by the IRSN’s report on the European Committee on Radiation Risk (ECRR).
Consultation on a second draft closed in the summer. Our responses can be seen on the ICRP site
The ICRP 2004 draft contains many statements revealing the incomplete state of knowledge of radiation risk. Many of them have been watered down in the 2006 draft or have disappeared altogether.
Here we reproduce extracts from the 2004 draft which confirm the validity of our long-standing concerns about heterogeneity of energy distribution. The ICRP’s response to heterogeneity is to employ assumptions. Most are individually questionable and when taken together, as they must be, they are simply not acceptable as a system of radiation protection. The upshot is that “dose” is an effectively meaningless term yet the industry’s regulators have no other terms with which to assess and quantify risks. Reassurances about “trivial doses” are revealed as empty.
“3.2. Summary of health effects caused by ionising radiation
(37) The relationship between radiation exposures and health effects is complex. The physical processes linking exposure and doses in human tissues involve energy transport at the molecular level. The biological links between this energy deposition and the resulting health effects involve molecular changes in cells. In Publication 60 (ICRP, 1991) , the Commission recognised that the gross (macroscopic) quantities used in radiological protection omitted consideration of the discontinuous nature of the physical and biological processes of ionisation. However, it concluded that their use was justified empirically by the observation that the gross quantities (with adjustments for different types of radiation) correlate reasonably well with the resulting biological effects. It further recognised that more use might eventually be made of other quantities based on the statistical distribution of events in a small volume of material, corresponding to the dimensions of biological entities such as the nucleus of the cell or its DNA. Meanwhile, for practical reasons, the Commission continues to use the macroscopic quantities.
[…]
3.3. Absorbed dose in radiological protection
(41) A particular feature of ionising radiations is their discontinuous interaction with matter. The related probabilistic nature of energy depositions results in distributions of imparted energy on a cellular and molecular level that are very heterogeneous at low doses. […]
(42) […] At the low doses generally of concern in radiological protection, the fluctuation of energy imparted can be substantial between individual cells and within a single hit cell. This is the case particularly for densely ionising radiations such as alpha-particles and charged particles from neutron interactions.
[…]
(44) Absorbed dose is defined based on the expectation value of the stochastic quantity e, energy imparted, and therefore does not consider the random fluctuation of the interaction events. It is defined at any point in matter and, in principle, is a measurable quantity, i.e. it can be determined experimentally and by computation. The definition of absorbed dose has the scientific rigour required for a fundamental quantity. It takes implicitly account of the radiation field as well as of all of its interactions inside and outside the specified volume. It does not, however, consider the atomic structure of matter and the stochastic nature of the interactions.
[…]
(46) For densely ionising radiation (charged particles from neutrons and alpha-particles) and low doses of low LET radiation, the frequency of events in most cells is zero, in a few it is one and extremely exceptionally more than one. The value of energy imparted in most individual cells is then zero but in the hit cells it will exceed the mean value by orders of magnitude. These large differences in the energy deposition distribution in microscopic regions for different types (and energies) of radiation have been related to observed differences in biological effectiveness or radiation quality.
(47) In the definition of radiological protection quantities no attempts are made to specify these stochastic distributions at a microscopic level. Even the quality factor used in the definition of operational quantities is dependent on LET only which also is a non stochastic quantity. Instead a pragmatic and empirical approach has been adopted to take account of radiation quality differences – and therefore implicitly also of the differences in distributions of energy imparted in microscopic regions – by defining radiation weighting factors. The selection of these factors is mainly a judgement based on the results of radiobiological experiments.
3.3.2. Radiological protection quantities: Averaging of dose
(48) While absorbed dose is defined to give a specific value (averaged in time) at any point in matter, averaging of doses over larger tissue volumes is often performed when using the quantity absorbed dose in practical applications, as in radiological protection. It is especially assumed for stochastic effects at low doses that such a mean value can be correlated with the risk of a detriment to this tissue with sufficient accuracy. The averaging of absorbed dose and the summing of mean doses in different organs and tissues of the human body, as given in the definition of all the protection quantities, is only possible under the assumption of a linear dose-response relationship with no threshold (LNT). All protection quantities rely on these hypotheses.
(49) Protection quantities are based on the averaging of absorbed dose over the volume of a specified organ or tissue. The extent to which the average absorbed dose in an organ is representative of the absorbed dose in all regions of the organ depends on a number of factors. For external radiation exposure, this depends on the degree of penetration of the radiation incident on the body. For penetrating radiation (photons, neutrons) , the absorbed dose distribution within a specified organ may be sufficiently homogeneous and thus the average absorbed dose is a meaningful measure of the absorbed dose throughout the organ or tissue. For radiation with low penetration or limited range (low-energy photons, charged particles) as well as for widely distributed organs (e.g. bone marrow) exposed to non-uniform radiation flux, the absorbed dose distribution within the specified organ may be very heterogeneous.
(50) For radiations emitted by radionuclides residing within the organ or tissue, so-called internal emitters, the absorbed dose distribution in the organ depends on the penetration and range of the radiations and the homogeneity of the activity distribution within the organs or tissues. The absorbed dose distribution for radionuclides emitting alpha particles, soft beta particles, low-energy photons, and Auger electrons may be highly heterogeneous. This heterogeneity is especially significant if radionuclides emitting low-range radiation are deposited in particular parts of organs or tissues, e.g. plutonium on bone surface or radon daughters in bronchial mucosa and epithelia. In such situations the organ-averaged absorbed dose may not be a good dose quantity for estimating the stochastic damage. The applicability of the concept of average organ dose and effective dose may, therefore, need to be examined critically in such cases and sometimes empirical and pragmatic procedures must be applied. ICRP has developed dosimetric models for the lungs, the gastrointestinal tract and the skeleton that take account of the distribution of radionuclides and the location of sensitive cells in the calculation of average absorbed dose to these tissues.
3.3.3. Radiation weighted dose and effective dose
(51) The definition of the protection quantities is based on the mean absorbed dose …
It seems perverse that having admitted so many flaws in the concept of absorbed dose ICRP simply continues to use it.
The 1991 assertion (see ICRP para. 37 above) that the use of macroscopic quantities is justified empirically is not acceptable. In the ensuing 15 years developments in cell biology and epidemiology, particularly following Chernobyl, have rendered it unsafe. The European Committee on Radiation Risk (ECRR) has recently developed weighting factors to compensate for some of the shortcomings of the ICRP approach. IRSN’s 2005 report on ECRR states: http://www.euradcom.eu/2005/irsn%20rapport%20ecrr-en.pdf
“Various questions raised by the ECRR are quite pertinent and led IRSN to analyze this document with a pluralistic approach.
a. Besides natural and medical exposures, populations are basically undergoing low dose and low dose rate prolonged internal exposures. But the possible health consequences under such exposure conditions are ill-known. Failing statistically significant observations, the health consequences of low dose exposures are extrapolated from data concerning exposures that involve higher dose rates and doses. Also, few epidemiologic data could be analyzed for assessing inner exposure effects. The risks were thus assessed from health consequences observed after external exposure, considering that effects were identical, whether the exposure source is located outside or inside the human body. However, the intensity, or even the type of effects might be different.
b. The pertinence of dosimetric values used for quantifying doses may be questioned. Indeed, the factors applied for risk management values are basically relying on the results from the Hiroshima and Nagasaki survivors’ monitoring. It is thus not ensured that the numerical values of these factors translate the actual risk, regardless of exposure conditions, and especially after low dose internal exposure.
c. Furthermore, since the preparation of the ICRP 60 publication, improvements in radiobiology and radiopathology, or even in general biology, might finally impair the radiation cell and tissue response model applied to justify radioprotection recommendations. It was thus justified to contemplate the impact of such recent observations on the assessment of risk induced by an exposure to ionizing radiation.”
IRSN’s report concludes:
“The phenomena concerning internal contamination by radionuclides are complex because they involve numerous physico-chemical, biochemical and physiological mechanisms, still ill-known and thus difficult to model. Due to this complexity, the behaviour of radionuclides in the organism is often ill described and it is difficult to accurately define a relationship between the dose delivered by radionuclides and the observed consequences on health. This led the radioprotection specialists to mostly use the dose/risk relationships derived from the study of the Hiroshima/Nagasaki survivors, exposed in conditions very different from those met in the cases of internal contaminations.
This fact raises numerous questions, which should be considered with caution because a wide part of the public exposure in some areas of the world is due to chronic internal contaminations and very few data concern these situations.
[…] the questions raised by the ECRR are fully acceptable, … ”
and
“… we do not possess, in the current state of knowledge, the elements required to improve the existing radioprotection system.”
We realise that we are inviting the rejoinder that IRSN also says:
[however] “the fact is that the [ECRR’s] arguments stated to justify this doctrine modification are not convincing, as the demonstration as a whole does not meet the criteria of a strict and consistent scientific approach.”
and
“the existing radioprotection system corresponds to the best tool being available at present for protecting human from the deleterious effects of ionizing radiations.”
and
“… a significant improvement of the radioprotection system in the field of internal contamination [can be] conceivable only by development of studies and research. ”
See this link for ECRR’s response to various points made by IRSN, and for the IRSN report itself. http://www.euradcom.eu/2005/irsn.htm
IRSN’s statements are a bizarre double standard; they have agreed with ECRR’s criticisms of the ICRP system, which on that basis can itself be described as “not meet[ing] the criteria of a strict and consistent scientific approach” (as IRSN demands of ECRR). IRSN’s subsequent call for more research may be only what is expected of scientists, but such research would take years. Policy makers and stakeholders engaged in decommissioning have to make decisions now.
CERRIE: DOSE IS “MEANINGLESS”
… There are important concerns with respect to the heterogeneity of dose delivery within tissues and cells from short-range charged particle emissions, the extent to which current models adequately represent such interactions with biological targets, and the specification of target cells at risk. Indeed, the actual concepts of absorbed dose become questionable, and sometimes meaningless, when considering interactions at the cellular and molecular levels.

ICRP throws in the towel
At a meeting in Stockholm, 22 April 2009, Dr Jack Valentin, Scientific Secretary Emeritus of the ICRP admitted that ICRP’s risk model could not be applied to post-accident exposures because the uncertainties were two orders of magnitude. (see transcript) http://www.llrc.org/llrc/health/subtopic/icrpabdicates.htm
The next day, Deputy Director of Strålsäkerhetsmyndigheten, Carl-Magnus Larsson also said the ICRP model could not be used to predict the health consequences of accidents. He added that for elements like Strontium and Uranium which bind to DNA national authorities would have the responsibility to assess the risks. Another SRM member said that the Secondary Photoelectron Effect was well recognised, also that in 1977 the ICRP had considered a weighting factor ”n” for elements which bind to DNA but had not implemented it.
