Radioactive fallout a risk factor for hypothyroidism

Elevated airborne beta levels in Pacific/West Coast US States and trends in hypothyroidism among newborns after the Fukushima nuclear meltdown, Scientific Research, Joseph J. ManganoJanette D. Sherman, 2 March 16 

ABSTRACT

Various reports indicate that the incidence of congenital hypothyroidism is increasing in developed nations, and that improved detection and more inclusive criteria for the disease do not explain this trend entirely. One risk factor documented in numerous studies is exposure to radioactive iodine found in nuclear weapons test fallout and nuclear reactor emissions.

Large amounts of fallout disseminated worldwide from the meltdowns in four reactors at the Fukushima-Dai-ichi plant in Japan beginning March 11, 2011 included radioiodine isotopes. Just days after the meltdowns, I-131 concentrations in US precipitation was measured up to 211 times above normal. Highest levels of I-131 and airborne gross beta were documented in the five US States on the Pacific Ocean. The number of congenital hypothyroid cases in these five states from March 17-December 31, 2011 was 16% greater than for the same period in 2010, compared to a 3% decline in 36 other US States (p < 0.03). The greatest divergence in these two groups (+28%) occurred in the period March 17-June 30 (p < 0.04). Further analysis, in the US and in other nations, is needed to better understand any association between iodine exposure from Fukushima-Dai-ichi and congenital hypothyroidism risk…….http://www.scirp.org/journal/PaperInformation.aspx?PaperID=28599

Japanese Government Takes Grave Risks with Radiation Exposure

radiation-warningflag-japanHow Much Is Too Much? Japanese Government Takes Grave Risks with Radiation Exposure  http://www.stuarthsmith.com/how-much-is-too-much-japanese-government-takes-grave-risks-with-radiation-exposure/  28 Feb 16 Japan’s nuclear crisis isn’t going away – and long-term health impacts from the radiation are now a grave concern as the situation continues to escalate. Dozens of repair workers at the reeling Fukushima-Daiichi nuclear power plant have already been exposed to radiation levels well beyond the country’s legal yearly dose limit. So far, the highest specific exposures reported are from two workers who received – on one day alone – radiation doses of more than three times the internationally recognized annual occupational exposure limit. Reports say the workers had severe rashes on the parts of their bodies exposed to radioactive water. Those troubling revelations prompted an even more troubling response from the Japanese government. In a move that is certain to stunt workers’ lives and potentially plague future generations with increased cancer rates, Japan’s Ministry of Health, Labor and Welfare has lifted the internationally recognized 50-millisievert (mSv) yearly cap on occupational exposure. That specific 50-mSv limit is recognized as the lowest dose that can trigger cancer in adults. It is most definitely not an arbitrary number to be manipulated by short-sighted governments – not even during times of crisis.

Japan’s decision to abolish the cap is just the latest bombshell in a series of potentially devastating policy changes made in recent weeks, coming on the heels of government officials upping the yearly legal limit of 100 mSv in “emergency situations” to 250 mSv for workers at the Fukushima plant. To put that in perspective,

The social toll on Fukushima families

For some Fukushima mothers, protecting children from radiation comes at heavy price, Asahi Shimbun February 23, 2016 Three-and-a-half years after fleeing to central Japan, a mother received a package from her husband who had opted to remain at their home in Fukushima Prefecture despite the nuclear disaster.

From Tamura, about 35 kilometers west of the stricken Fukushima No. 1 nuclear plant, the father sent snacks for the couple’s two children. The cardboard box also contained divorce papers.

“I cannot send money to my family whom I cannot see,” the husband told his wife.

She still refused to return home.

Thanks to decontamination work, radiation levels have fallen around the nuclear plant since the triple meltdown caused by the Great East Japan Earthquake and tsunami in March 2011. And families are returning to their hometowns, trying to resume normal lives.

But many mothers, distrustful of the government’s safety assurances, still harbor fears that radiation will affect the health of their children. As a result of these concerns, families are being torn apart, friendships have ended, and a social divide remains wide in Fukushima communities.

Around 70,000 people are still not allowed to return to their homes located in evacuation zones designated by the central government. And an estimated 18,000 people from Fukushima Prefecture whose homes were outside those zones remain living in evacuation………..

Sung Woncheol, a professor of sociology at Chukyo University, and others have conducted surveys on mothers whose children were 1 to 2 years old when the nuclear disaster started. The mothers live in Fukushima city and eight other municipalities in Fukushima Prefecture.

Of the 1,200 mothers who responded to the survey in 2015, 50 percent said they had concerns about child-rearing in Fukushima Prefecture.

Nearly 30 percent said they avoid or try to avoid using food products from Fukushima Prefecture, compared with more than 80 percent six months after the disaster.

But for some mothers, the passage of nearly five years since the disaster unfolded has not erased their fears of radiation.

The 36-year-old mother who received the divorce papers from her husband in autumn 2014 continues to live with her children in the central Japan city to which she had no previous connection.

A month after the nuclear disaster, she fled with her then 1-year-old son and her daughter, 10, from their home, even though it was not located in an evacuation zone.

She said she left Fukushima Prefecture because she “could not trust the data released by the central government.”……..http://ajw.asahi.com/article/0311disaster/fukushima/AJ201602230068

Thousands of nuclear workers made sick by radiation, but not getting any help

Sen. Tom Udall, D-N.M., is among a group of federal lawmakers who have called for an investigation into the program following McClatchy’s probe, which revealed 7,762 workers died after being denied compensation by the government.

The McClatchy DC investigation found that nuclear worker safety remains an issue: Since 2001, more than 186,000 workers have been exposed to radiation.

Flag-USAEfficacy of compensation program for nuclear workers under scrutiny By Rebecca Moss
The New Mexican, 20 Feb 16, “………Due to the commingling of his exposure during the war and his work on various sites at Sandia, Thompson is one of at least 10,273 New Mexicans who have applied for a federal program that compensates individuals with a $150,000 lump sum payment for serious illness or death that can be attributed to work at the state’s nuclear defense facilities since 1943.

Since Congress passed the Energy Employees Occupational Illness Compensation Program Act in 2000, the government has spent $12 billion in financial restitution for more than 100,000 workers whose onset of cancer, beryllium disease, neurological disorders and other ailments is a result of careers in the more than 300 nuclear facilities across the country.

As of March 2015, New Mexico had received the second-highest compensation of any state under the fund, with $1.64 billion paid out to workers for compensation and medical bills.

But the program has come under scrutiny lately. An investigation by the McClatchy DC news service found that fewer than half of the people who have applied for benefits have received them, and workers’ complaints are often suspended in the complex process of paperwork or court hearings, with some claims languishing in the system for up to 10 years. A new documentary coming out in March, titled Safe Side of the Fence, questions why side-by-side workers with similar ailments would receive different judgments from the Department of Labor on the validity of their claims.

At least 5,400 workers in New Mexico have been denied financial assistance, according to the Department of Labor, which issues the compensation.

The department recently added new language to the regulations, which is intended to clarify who is eligible for relief. A 60-day public comment period for the proposal ended Thursday. But critics say the new language could make it even more difficult for ailing workers to receive compensation. Continue reading

Leukaemia risk increased in exposure even to low dose radiation – World Health Organisation

logo WHOEven low doses of radiation increase risk of dying from leukaemia in nuclear workers, says IARC  http://www.iarc.fr/en/media-centre/pr/2015/pdfs/pr235_E.pdf  Lyon, France, 22 June 2015 A study coordinated by the International Agency for Research on Cancer (IARC), the specialized cancer agency of the World Health Organization, shows that protracted exposure to low doses of ionizing radiation can cause leukaemia. The study, published today in The Lancet Haematology, shows that the risk of death from leukaemia increases linearly with the radiation dose.

 “To date, this study provides the most precise evaluation of the risk of developing leukaemia linked to the protracted low doses of radiation received by nuclear workers throughout their careers,” says IARC researcher Dr Ausrele Kesminiene, a study co-author. “It shows that the nuclear workers we studied have a small increase in the risk of dying from leukaemia as their exposure to radiation increases.”
 Low-dose exposures are typical of environmental or occupational exposures, such as exposure of nuclear workers at their workplace, but also of medical exposures, such as patients undergoing multiple computed tomography (CT) scans through medical diagnostic procedures. The study Based on the strongest evidence currently available, the International Nuclear Workers Study (INWORKS), a collaboration1 among international partners, evaluated the exposures of more than 300 000 nuclear workers in France, the United Kingdom, and the USA over a period of time between 1943 and 2005. The study assessed the risk of developing certain cancers, such as leukaemia, lymphoma, and multiple myeloma.
The results 
The study results highlight strong evidence for a positive association between exposure to ionizing radiation and risk of death from leukaemia and show that the risk of leukaemia increases linearly with radiation dose. 

16 new child thyroid cancers confirmed in Fukushima’s children

thyroid-cancer-papillaryFukushima medical survey confirms 16 new child thyroid cancer cases Rt.com 17 Feb, 2016 At least 16 cases of thyroid cancer in children have been confirmed in a follow-up medical survey of those exposed to the 2011 Fukushima nuclear disaster. According to the prefectural government panel, at least 35 more minors thought to have the disease.

The prefectural government is giving medical checkups to all 380,000 children aged 18 or younger at the time of the accident at the Fukushima Daiichi plant in March 2011. Since the latest checkup began in April 2014, 16 children have been confirmed to have the potentially deadly condition that stems from radiation exposure, according to Japan Today.

In addition, the combination of two surveys showed that now at least 116 children are suffering from thyroid cancer with at least 50 other minors suspected of having the disease. Medical testing facilities involved in the study said that 51 children in the second round of the survey had tumors ranging from 5.3 millimeters to 30.1 mm in size.

The medics also estimated that the external exposure of 29 children in the four months following the catastrophe had gone up to 2.1 millisieverts. Ten minors had been exposed to less than 1 millisievert…….https://www.rt.com/news/332708-fukushima-survey-thyroid-cancer/

Official Canadian report reveals Fukushima radioactive iodine in rain reached West Coast of America

Official Report: West Coast hit with 220,000,000 atoms per liter of Iodine-129 in rain after Fukushima — 15 Million year half-life — Detected in aquifer that supplies drinking water to large number of people — “Transported rapidly” to Canada and US — Elevated levels continued for many months http://enenews.com/official-report-west-coast-hit-220000000-atoms-liter-iodine-129-rain-after-fukushima-15-million-year-half-life-detected-groundwater-transported-rapidly-japan-west-coast-canada-elevated-lev


Matt Herod, Univ, of Ottawa Ph.D Candidate, Dec 21, 2015 (emphasis added): A recently published paper (by myself and colleagues from uOttawa and Environment Canada) investigates… [Iodine-129] which was released by the Fukushima-Daichii [sic] Nuclear Accident… Within 6 days of the FDNA 129I concentrations in Vancouver precipitation increased 5-15 times… sampling of groundwater revealed slight increases in 129I… The results in rain show an increase in 129I concentrations of up to 220 million atoms/L… 129I anomalies [in groundwater wells], which occurred exactly when the recharge age predicted they would, suggests that some of the 129I deposited by Fukushima was reaching the wells… [P]ulses of elevated 129I occurred for another several months. Elevated 129I concentrations were measured in two wells… indicating that 129I from Fukushima can be traced into groundwater… [M]odeling has shown that 129I can be rapidly transported to the water table

Scientists from Univ. of Ottawa’s Dept. of Earth Science and Environment Canada (Government of Canada), Dec 2015: The atmospheric transport of iodine-129 from Fukushima to British Columbia, Canada and its deposition and transport into groundwater

  • The Fukushima-Daiichi nuclear accident (FDNA) released iodine-129 (15.7 million year half-life)… The mean pre-accident 129I concentration in rain was [31,000,000 atoms/L]… following the FDNA, 129I values increased to [211,000,000 atoms/L]… [P]ulses ofelevated 129I continued for several months
  • The 129I in shallow… groundwater showed measurable variability through March 2013 with an average of [3,200,000 atoms/L]… coincident with modeled travel times…
  • Radionuclides released from the FDNA have been detected across the globe… [R]eleases of 129I and 131I… travel great distances
  • The Abbotsford-Sumas Aquifer… spans the Canada–U.S. border between [B.C., Canada and Washington, US] and supplies ∼120,000 people with drinking water
  • A pulse of 129I in precipitation with maximum concentrations of [211,000,000 atoms/L] in Vancouver and [221,000,000 atoms/L] at Saturna Island was observed 6 days following the FDNA. A value of [311,000,000 atoms/L] was also measured during the first week of July…
  • The high 129I concentrations while the FDNA was ongoing are attributed to the rapid trans-Pacific transport of 129I from Fukushima… This response in 129I concentrations shows that radionuclides from Fukushima were transported rapidly from Japan to the west coast of Canada and the US… [Sampling from Washington State], which is a composite of rainfall events spanning 15 March 2011 to 16 April 2011shows a significantly elevated 129I concentration of [95,000,000 atoms/L]…
  • There was a spike in 129I concentration observed in the precipitation sample from the period of 1 July 2011 to 8 July 2011 [which] rose to [311,000,000 atoms/L]… a substantially higher concentration than any other sample… As monitoring at Fukushima detected no pulse of 129I in precipitation in July… this spike is likely due to a… nuclear fuel reprocessing facility. Modeling of the air parcel back trajectories… for the sampling period shows air mass trajectories from Hawaii, north Japan, and Russia…
  • The initial increase in 129I concentration at the water table appeared within ∼95 days, with a maximum concentration of [10,500,000 atoms/L]…
  • In the model cases, 129I reached the water table very rapidly
  • Groundwater 129I concentrations in two nearby wells showed minor anomalies over the sampling period which could be due to rapid infiltration of the FDNA atmospheric 129Isignal… [M]odeling shows that it was possible for a component of the 129I deposited by the FDNA to be conducted rapidly from the ground surface to the water table… We conclude that it is possible that a fraction of 129I from the FDNA is transported conservatively in this aquifer via preferential flow paths to the water table…

Fukushima radiation monitored by citizen science

How Citizen Science Changed the Way Fukushima Radiation is Reported, National Geographic  by Ari Beser in Fulbright National Geographic Stories on February 13, 2016 Tokyo “It appears the world-changing event didn’t change anything, and it’s disappointing,”said Pieter Franken, a researcher at Keio University in Japan (Wide Project), the MIT Media Lab (Civic Media Centre), and co-founder of Safecast, a citizen-science network dedicated to the measurement and distribution of accurate levels of radiation around the world, especially in Fukushima. “There was a chance after the disaster for humanity to innovate our thinking about energy, and that doesn’t seem like it’s happened.  But what we can change is the way we measure the environment around us.”

Franken and his founding partners found a way to turn their email chain, spurred by the tsunami, into Safecast; an open-source network that allows everyday people to contribute to radiation-monitoring……….

Since their first tour of Koriyama, with the help of a successful Kickstarter campaign, Safecast’s team of volunteers have developed the bGeigie handheld radiation monitor, that anyone can buy on Amazon.com and construct with suggested instructions available online. So far over 350 users have contributed 41 million readings, using around a thousand fixed, mobile, and crowd-sourced devices.

According to Franken, “We’re working with communities to install these sensors in people’s neighborhoods. We’re financed by donations only. We get donations so we put together a plan, volunteers provide space, and Internet access, and agree that the data collected are public.

“What we’ve come to determine in Fukushima is that radiation levels are spotty. They can vary from street corner to street corner. We’ve also been able to determine that the levels over the last five years have reduced, partly because of half life of cesium, and because of environmental factors. We’ve also seen an increase in official government data being released in a similar style to Safecast’s drive-by method versus spot checking.”

According to Franken, “There is no safe dose of radiation as it’s debated by scientists; the higher the level, the higher the risk is that it will trigger a cancer. Though, at low levels the risk is much smaller, it is not zero. ……..

One of the biggest problems in Fukushima is the anxiety and the uncertainty that people are suffering from the incident. I think what were doing is trying to alleviate that by giving them ways to educate themselves about the problem and giving them solutions where they can be empowered to do something about it, as a opposed to just going along with the current of the crisis.” http://voices.nationalgeographic.com/2016/02/13/how-citizen-science-changed-the-way-fukushima-radiation-is-reported/

Epidemiology studies needed around nuclear facilities. Why is this ignored by authorities?

 Childhood leukemialow birth weightcompromised neural development are all associated with exposure to radiation during pregnancy and early childhood.

Astonishingly, no official body in the United States is seriously investigating these impacts. In fact, the U. S. federal government appears not to conduct public health impact studies of populations around nuclear power reactor sites.

Who is monitoring the health of populations around nuclear power
questionplants?, 
http://enformable.com/2016/02/who-is-monitoring-health-of-populations-around-nuclear-power-plants/ Enformable, Cindy Folkers Author’s note: I wrote this blog post with knowledge of the ongoing tritium leaks plaguing a number of  nuclear power reactors in the U.S., but before the latest high levels of tritium released from the Indian Point reactor in New York were reported. These recent unplanned and largely unaccounted for releases bring into stark relief the need to measure in real time the releases we DO initially control; further, it is reasonable to request public access to these data.

Humans have known of natural radioactivity since about the turn of the 20th century when Marie Curie carried around vials of radioactive substances in her pocket, admiring the glow-in-the-dark “fairy lights” they would give off. Long-term exposure to these “fairly lights” made Curie chronically ill, physically scarred, and nearly blind from cataracts. At the age of 66, she succumbed to a radiation-induced disease (either leukemia or aplastic anemia, sources differ), as did her daughter and son-in-law. Despite being deeply troubled by deaths of colleagues and radiation workers, the Curies never really admitted radioactivity played a role in their diseases; Marie even recommended sickened radium dial painters eat calf’s liver to combat anemia. Daughter Eva, who outlived her sister by 50 years, died at 102 and recognized the role radiation played in the shortened lives of her female kin.

This denial of the dangers of radioactivity has carried through to the present day. When the Environmental Protection Agency (EPA) issued its first-ever radiation exposure standards in 1977, the US was only 20 years into the atomic energy age, barely long enough to see many of the health impacts radioactivity may have had. Man-made radioactivity had been around for about 40 years with the building of the bomb, well before EPA was established, but well after some very nasty health effects from larger doses were recognized.  Now, in 2015, EPA is considering revising its radiation standards – the first major revision since 1977.

EPA is responsible for regulating radioactive emissions that migrate off of a site that releases such material. These off site releases can expose members of the public and their environment. Revision of these nearly 40-year old standards should be a good thing; adding protection for women who are 50 % more sensitive to radioactivity than men; and providing proper protection for pregnancy and childhood development —life stages that are particularly, in some cases uniquely, sensitive to exposure to radioactivity. But old habits, and nuclear industry interference, die hard. Continue reading

The role of LEAD in damaging brains and contributing to violence

an astonishing body of evidence. We now have studies at the international level, the national level, the state level, the city level, and even the individual level. Groups of children have been followed from the womb to adulthood, and higher childhood blood lead levels are consistently associated with higher adult arrest rates for violent crimes. All of these studies tell the same story: Gasoline lead is responsible for a good share of the rise and fall of violent crime over the past half century……

 It’s the only hypothesis that persuasively explains both the rise of crime in the ’60s and ’70s and its fall beginning in the ’90s.

text Epidemiology

A second study found that high exposure to lead during childhood was linked to a permanent loss of gray matter in the prefrontal cortex—a part of the brain associated with aggression control as well as what psychologists call “executive functions”: emotional regulation, impulse control, attention, verbal reasoning, and mental flexibility.

highly-recommendedLEAD – America’s real criminal element. Mother Jones, By Kevin Drum, February 16    “…………IN 1994, RICK NEVIN WAS A CONSULTANT working for the US Department of Housing and Urban Development on the costs and benefits of removing lead paint from old houses. This has been a topic of intense study because of the growing body of research linking lead exposure in small children with a whole raft of complications later in life, including lower IQ, hyperactivity, behavioral problems, and learning disabilities.

But as Nevin was working on that assignment, his client suggested they might be missing something. A recent study had suggested a link between childhood lead exposure and juvenile delinquency later on. Maybe reducing lead exposure had an effect on violent crime too?

That tip took Nevin in a different direction. The biggest source of lead in the postwar era, it turns out, wasn’t paint. It was leaded gasoline. And if you chart the rise and fall of atmospheric lead caused by the rise and fall of leaded gasoline consumption, you get a pretty simple upside-down U: Lead emissions from tailpipes rose steadily from the early ’40s through the early ’70s, nearly quadrupling over that period. Then, as unleaded gasoline began to replace leaded gasoline, emissions plummeted.

Gasoline lead may explain as much as 90 percent of the rise and fall of violent crime over the past half century. Continue reading

Thyroid cancer increasing: can they continue to ignore the link with nuclear power?

Studies of Japanese survivors of the atomic bombs the United States dropped on Hiroshima and Nagasaki found the cancer with the greatest increase was thyroid cancer.

  • A U.S. government survey of cancer rates among residents of the Marshall Islands, who were exposed to U.S. bomb testing in the 1950s, found thyroid cancer outpaced all others.
  • A 1999 federal study estimated that exposure to I-131 from bomb testing in Nevada caused as many as 212,000 Americans to develop thyroid cancer.
  • A 2009 book on the Chernobyl nuclear plant disaster found soaring levels of local thyroid cancer rates after the meltdown, especially among children, and workers called “liquidators,” who cleaned up the burning plant.
  • More recently, studies have documented thyroid cancer rates in children near Fukushima, Japan, site of the 2011 meltdown, to be 20 to 50 times above the expected rate.

thyroid-cancer-papillaryAN INVISIBLE EPIDEMIC http://linkis.com/washingtonspectator.org/cxhdO  Can an epidemic really sneak up on us like this?   By Janette Sherman and Joseph Mangano February 4, 2016 Is it possible for an epidemic to be invisible?

Since 1991 the annual number of newly documented cases of thyroid cancer in the United States has skyrocketed from 12,400 to 62,450. It’s now the seventh most common type of cancer.

Relatively little attention is paid to the butterfly-shaped thyroid gland that wraps around the throat. Many don’t even know what the gland does. But this small organ (and the hormone it produces) is crucial to physical and mental development, especially early in life.

Cancer of the thyroid also gets little attention, perhaps because it is treatable, with long-term survival rates more than 90 percent. Still, the obvious question is what is causing this epidemic, and what can be done to address it?

Recently, there has been a debate in medical journals, with several authors claiming that the increase in thyroid cancer is the result of doctors doing a better job of detecting the disease at an earlier stage. A team of Italian researchers who published a paper last January split the difference, citing increased rates and better diagnosis. But as rates of all stages of thyroid cancer are soaring, better detection is probably a small factor.

So, what are the causes?

The Mayo Clinic describes a higher frequency of occurrence of thyroid cancer in women (not a telling clue, unless more is known about what predisposes women to the condition). It mentions inherited genetic syndromes that increase risk, although the true cause of these syndromes aren’t known. And Mayo links thyroid cancer to exposure to radiation. The latter is perhaps the only “cause” for which there is a public policy solution.

In the atomic age, radioactive iodine (chiefly Iodine-131) has proliferated, from atom bomb explosions and now from nuclear power reactors. Continue reading

Low dose ionising radiation takes its toll on living organisms – Timothy Mousseau

radiation-warningEven low radiation dose can take toll: scientist http://www.chinapost.com.tw/taiwan/national/national-news/2016/01/27/457138/Even-low.htm By Enru Lin, The China Post  TAIPEI, Taiwan–Animals exposed to even low doses of radiation suffer a higher incidence of physical abnormalities, a world-leading ecologist said in Taipei on Tuesday.  Timothy Mousseau, an ecologist at the University of South Carolina, is a pioneering expert on what radiation does to organisms.

For decades, he and his research team have studied Chernobyl, Ukraine — site of the world’s worst nuclear disaster in 1986 — and Fukushima in Japan.

Their studies found that radiation exposure had significant effects on local populations, for instance causing tumors, small brain sizes, sterility and cataracts in birds in Chernobyl.

No Safe Dose?

Findings indicate that radiation, even at low doses, can increase mortality rates and the incidence of physical abnormalities.

“There is no threshold below which there is no effect on organisms,” Mousseau said.

“We need to be very concerned not only about the consequences of nuclear accidents, but also the regular day-to-day operations of nuclear power plants, where radiation is released on a regular basis.”

Call for Taiwan Research

Mousseau was speaking on invitation at a press briefing and forum at the Legislative Yuan, where he was joined by three Democratic Progressive Party (DPP) lawmakers including Tien Chiu-chin (田秋堇).

At the event, anti-nuclear activists called on the central government to commission an independent research team to study effects on people who live near Taiwan’s three operating nuclear power plants.

Birds, Butterflies First

Mousseau said his data suggested that some organisms were far more sensitive to radiation than others.

Studies from Chernobyl and Fukushima showed that the first significant effects of radiation occurred in the same taxonomic groups.

“Birds and butterflies are the two most sensitive groups — we saw immediate large responses in birds and butterflies in Fukushima,” he said.

Other animals, such as grasshoppers and spiders, are less susceptible to the effects of radiation.

On Humans

Meanwhile, there is insufficient research on the human population to make convincing assessments on the impact of low dose radiation.

Mousseau said that in the U.S., studies are thwarted when researchers can’t access the relevant health records.

“There are privacy issues related to health records that are so strong in the United States, and there is a lack of organization of the registries. That makes it very difficult to do solid, hard science,” he said.

Local medical cyclotrons, not nuclear reactors, best for producing medical isotopes

This production method for Tc-99m can be used by retrofitting various brands of conventional cyclotrons already in use in hospitals and health centres across Canada.
 Depending on the machine capability, a large metropolitan area could be supplied by a single dedicated, or a handful of partially dedicated, medical cyclotrons.
cyclotron - small partcle accelerator, CanadaMedical isotope production in Australia: Should we be using reactor based or cyclotron technology? 15th January 2016  Dr Margaret Beavis MBBS FRACGP MPH Medical Association for Prevention of War, Australia Health Professionals Promoting Peace  “…….Cyclotron isotope production A cyclotron is an electromagnetic device (about the size of a four wheel drive car) used to accelerate charged particles (ions) to sufficiently high speed (energy) so that when it impinges upon a target the atoms in the target are transformed into another element. 10 In other words, it uses electricity and magnets to shoot a narrow beam of energy at elements, e.g. molybdenum-100, a natural material, and this produces technetium-99.
A cyclotron differs from a linear accelerator in that the particles are accelerated in an expanding spiral rather than in a straight line.
The Canadian approach In 2009 the Canadian Government Expert Review Panel on Medical Isotope Production recognised that cyclotron technology could readily be adapted to produce isotopes.
Drawing from expertise in physics, chemistry, and nuclear medicine, the team of Canadian researchers (Triumf Cyclomed99 group11 ) set out to develop a reliable, alternative means of production for a key medical isotope Technetium-99m (Tc-99m). In early 2015 they announced they had developed technology that uses medical cyclotrons already installed and operational in major hospitals across Canada to produce enough Tc-99m on a daily basis. They also successfully addressed issues for several other less commonly used isotopes.12
This production method for Tc-99m can be used by retrofitting various brands of conventional cyclotrons already in use in hospitals and health centres across Canada. They state proposed upgrades to existing medical cyclotrons and production sites can be done quickly and cost effectively. This allows for rapid deployment of the technology which can be scaled to meet regional demands.
 Depending on the machine capability, a large metropolitan area could be supplied by a single dedicated, or a handful of partially dedicated, medical cyclotrons. By enabling regional hospitals to produce  and distribute isotopes to local clinics, widespread supply disruptions can be avoided.
The Canadians also believe cyclotrons create new opportunities to export technology to international partners and across multiple business sectors. Other uses exist for nearly all aspects of this technology, with potential applications that have benefits toward other aspects of nuclear medicine, molecular imaging and non-related fields.
By the completion of the project, the research team will be producing Tc-99m on three different brands of medical cyclotrons at a commercial scale. Production and distribution of this most commonly used isotope from a regional supply hub will de-centralize the process, helping to avoid future isotope shortages.
Clinical trials began in Canada in early 2015. 13 In Canada there are plans to have 24 cyclotrons operating by 2018. But it is likely to be several years before cyclotron production is able to fully substitute for the reactor based isotope production. The Canadian example is useful given some similarities in population, geographic size and city size.
Worldwide many hospitals in major urban centres operate cyclotrons. There are currently over 950 small medical cyclotrons manufactured by several companies (ACSI, GE, IBA, Siemens, Sumitomo, Best, etc.) installed around the world. Approximately 550 of these machines operate above 16 MeV and are capable of producing appreciable quantities of Tc- 99m. Existing cyclotrons would need to be upgraded to maximize beam current onto a single target. It is important to note that cyclotron production still needs considerable work to become mainstream……..https://www.mapw.org.au/files/downloads/Medical%20isotope%20production%20MAPW%20Background%20paper%20with%20exec%20summary.pdf

How long are people going to tolerate this nuclear tragedy?

death-nuclearThe Shockingly High Number of Casualties of America’s Nuclear Weapons Program  http://historynewsnetwork.org/article/161607?__scoop_post=74a15000-b971-11e5-b8b0-00221934899c&__scoop_topic=2427585#__scoop_post=74a15000-b971-11e5-b8b0-00221934899c&__scoop_topic=2427585  by Lawrence S. Wittner– When Americans think about nuclear weapons, they comfort themselves with the thought that these weapons’ vast destruction of human life has not taken place since 1945—at least not yet. But, in reality, it has taken place, with shocking levels of U.S. casualties.

This point is borne out by a recently-published study by a team of investigative journalists at McClatchy News. Drawing upon millions of government records and large numbers of interviews, they concluded that employment in the nation’s nuclear weapons plants since 1945 led to 107,394 American workers contracting cancer and other serious diseases. Of these people, some 53,000 judged by government officials to have experienced excessive radiation on the job received $12 billion in compensation under the federal government’s Energy Employees Occupational Illness Compensation Program. And 33,480 of these workers have died.

How could this happen? Let’s examine the case of Byron Vaigneur. In October 1975, he saw a brownish sludge containing plutonium break through the wall of his office and start pooling near his desk at the Savannah River, South Carolina nuclear weapons plant. Subsequently, he contracted breast cancer, as well as chronic beryllium disease, a debilitating respiratory condition. Vaigneur, who had a mastectomy to cut out the cancer, is today on oxygen, often unable to walk more than a hundred feet. Declaring he’s ready to die, he has promised to donate his body to science in the hope that it will help save the lives of other people exposed to deadly radiation.

Actually, workers in nuclear weapons plants constitute only a fraction of Americans whose lives have been ravaged by preparations for nuclear war. A 2002 report by the U.S. Department of Health and Human Services maintained that, between 1951 and 1963 alone, the atmospheric testing of nuclear weapons—more than half of it done by the United States—killed 11,000 Americans through cancer. As this estimate does not include internal radiation exposure caused by inhaling or swallowing radioactive particles, the Institute for Energy and Environmental Research has maintained that the actual number of fatal cancers caused by nuclear testing could be 17,000. Of course, a larger number of people contracted cancer from nuclear testing than actually died of it. The government study estimated that those who contracted cancer numbered at least 80,000 Americans.

Who were these Americans? Many of them were “downwinders”—people whose towns and cities were located near U.S. nuclear testing sites and, thus, were contaminated by deadly clouds of nuclear fallout carried along by the wind. During the 1950s, the U.S. government conducted close to a hundred atmospheric nuclear explosions at its Nevada test site. Nearly 30 percent of the radioactive debris drifted over the towns to the east, which housed a population of roughly 100,000 people. The residents of St. George, Utah recalled that a “pink cloud” would hang over them while they worked amid the fallout, walked in it, breathed it, washed their clothes in it, and ate it. “Even the little children ate the snow,” recalled one resident. “They didn’t know it was going to kill them later on.”

During subsequent decades, leukemia and other cancer rates soared in the counties adjoining the Nevada test site, as they did among the 250,000 U.S. soldiers exposed to U.S. nuclear weapons tests. From the standpoint of U.S. military commanders, it was vital to place American soldiers close to U.S. nuclear explosions to get them ready to fight in a nuclear war. Subsequently, as many of these soldiers developed cancer, had children with birth defects, or died, they and their family members organized atomic veterans’ groups to demand that the federal government provide medical care and financial compensation for their suffering. Today, atomic veterans receive both from the federal government.

Uranium miners comprise yet another group of Americans who have suffered and died from the U.S. nuclear weapons program. To obtain the uranium ore necessary to build nuclear weapons, the U.S. government operated thousands of uranium mines, often on the lands of Native Americans, many of whom worked as miners and died premature deaths. The U.S. Public Health Service and the National Institute for Public Safety and Health conducted studies of uranium miners that discovered alarmingly high rates of deaths from lung cancer, other lung diseases, tuberculosis, emphysema, blood disease, and injuries. In addition, when the uranium mines were played out or abandoned for other reasons, they were often left as open pits, thereby polluting the air, land, and water of the surrounding communities with radiation and heavy metals.

This American nuclear catastrophe is not only a matter of the past, but seems likely to continue well into the future. The U.S. government is now beginning a $1 trillion program to “modernize” its nuclear weapons complex. This involves building new nuclear weapons factories and labs, as well as churning out new nuclear weapons and warheads for firing from the air, land, and sea. Of course, if these weapons and their overseas counterparts are used, they will destroy the world. But, as we have seen, even when they are not used in war, they exact a dreadful toll—in the United States and, it should be noted, in other nations around the world.   How long are people going to tolerate this nuclear tragedy?

Birth defects in families of Britain’s nuclear test veterans: the fight for justice

Their wives have been found to have three times the usual number of miscarriagesand even their grandchildren have eight times the normal amount of birth defects.

Nuclear test veterans bid for £1million to prove blasts caused cancer and birth defects http://www.mirror.co.uk/news/uk-news/nuclear-test-veterans-bid-1million-7147105 9 JAN 2016  BY  Britain’s nuclear heroes are bidding for a £1million research fund to finally prove the awful genetic legacy of the UK bomb tests.

Veterans are hoping the government cash will help them win a 60-year fight for justice after they were left with a crippling legacy of cancers , rare disease and 10 times the normal rate of birth defects in their children.

Nige Heaps of the British Nuclear Test Veterans’ Association said: “We hope that with this money we’ll be able to do the scientific work necessary to help prove the case, as well as improving the lives of survivors and their children.”

In his March budget Chancellor George Osborne praised the veterans’ campaign for recognition, backed by this newspaper, and announced a £25m fund to help all veterans over 60.

  • The BNTVA has spent the past nine months preparing a detailed bid which has already had draft approval and will be formally submitted on Monday.The £1m they are asking for includes:
    • £500,000 over two years for a genetic study by Brunel University
    • £250,000 for research by charity Combat Stress into the mental health effects
    • £150,000 for a two-year study at the University of Southampton on the sociological impact
    • £6,000 to begin a remembrance project and future archive
    • £94,000 to provide items like electric wheelchairs, home adaptations, transport or other help for those who need it

    There is no guarantee BNTVA will get a penny. The Aged Veterans Fund they are applying to has £5million next year to split between eight veterans’ groups expected to bid.

  • But Mr Heaps says he is confident of a breakthrough.He added: “There is no way scientifically to say any genetic damage was caused by radiation from the tests.

    “The best we can hope for is to prove the veterans have a higher rate of genetic damage than the rest of the population. We have to fight the battles we can win.”

    Around 22,000 men, many on National Service, were ordered to Australia and Christmas Island in the South Pacific from 1952 to witness the explosion of dozens of atomic and hydrogen bombs.

    They were forced to live amid the toxic fallout for up to a year afterwards.Read more: Nuclear test veterans fighting for £72k payout after being irradiated by the Government

    On their return, they began to report increased cases of blood, thyroid and tongue cancers and rare blood and bone disorders.

    Their wives have been found to have three times the usual number of miscarriagesand even their grandchildren have eight times the normal amount of birth defects.

  • The Ministry of Defence has always denied being to blame, and has spent millions fighting legal cases. Today fewer than 3,000 veterans survive, along with an estimated 150,000 descendants carrying the curse of their fathers’ service.But in 2007 genetic research in New Zealand – similar to that now proposed here – showed veterans had DNA damage three times worse than that suffered by survivors of Chernobyl.

    Derek Fiddaman has had 200 cancers removed from his face and head – and expects to develop 100 more.

    Derek was a 21-year-old naval rating on HMS Cossack when it was ordered to Christmas Island in 1957 as guardship for several hydrogen bomb tests codenamed Operation Grapple.

  • The crew was ordered on deck to watch the explosions.In 1975 he developed lumps on his face and began 40 years and 1,000 hospital visits to have basal cell carcinomas – cancers rooted in the deepest layer of skin – cut out.

    Derek, now 78, of Horsham, West Sussex, said: “I have about five cut out every year, so if I live another 20 years there’ll be 100 more.

    “Each time they cut one out and I go back and there’s another one growing in the scar.”

  • He’s one of those demanding the MoD admit irradiating them.He said: “I’m one of the lucky ones – it’s not going to kill me and they can at least cut my cancers out.

    “You get used to it. All I want is to hear the word ‘sorry’. They never will, but that’s all I want.”

    The proposed UK research will involve analysis of the DNA in blood and saliva of around 50 surviving veterans, wives and children, to assess genetic damage and see if it was passed on.

    It will also look for a “radiation signature” in the DNA, if one is present.

    If approved, the money will be released in the spring.http://www.mirror.co.uk/news/uk-news/nuclear-test-veterans-bid-1million-7147105
