October 26, 2011 The Toronto Star: Radiation Doses of 1,769 Health Care Workers Under-Reported for Four Years
by John Spears
“A system used by 1,769 health care and research workers to measure their workplace radiation exposure may have under-reported radiation levels since 2008, says the Canadian Nuclear Safety Commission.
The commission says a “calculation error” in the management system used by the devices is responsible for the low readings.
The errors led to potential under-reporting of radiation doses by 25 to 40 per cent, the commission says in a letter to Health Canada.” […]
Fukushima Hot Particles. Conference Presentation APHA 139th Meeting and Exposition, Washington, DC October 31, 2011: 8:30 AM Marco Kaltofen, PE, Department of Civil & Environmental Engineering, Worcester.
This will be a very interesting paper revealing results of air filter analysis in Japan and the US to determine the amount of “hot particles” present from Fukushima.
The Fukushima nuclear accident dispersed airborne dusts that are contaminated with radioactive particles. When inhaled or ingested, these particles can have negative effects on human health that are different from those caused by exposure to external or uniform radiation fields. A field sampling effort was undertaken to characterize the form and concentration of radionuclides in the air and in environmental media which can accumulate fallout. Samples included settled dusts, surface wipes, used filter masks, used air filters, dusty footwear, and surface soils. Particles were collected from used motor vehicle air filters and standard 0.45 micron membrane air filters. Soils and settled dusts were collected from outdoor surfaces, interior surfaces, and from used children’s shoes. The Japanese filters contained cesium 134 and 137, as well as cobalt 60 at levels as high as 3 nCi total activity per sample. Materials collected during April 2011 from Japan also contained Iodine 131. This short-lived nuclide was not observed in later samples. US air filter and dusts samples did not contain hot particles, except for air samples collected from Seattle, WA during the month of April 2011. [emphasis added] The samples of Japanese children’s shoes were found to have relatively high radiocesium contamination levels. Isolated US soil samples contained up to 8 nanoCuries per Kg of radiocesium, while control samples showed no detectable radiocesium. [emphasis added] Dusts containing radioactive cesium were found at levels orders of magnitude above background more than 100 miles from the accident site, and were detectable on the US west coast.[emphasis added]
October 20, 2011 The Georgia Straight: What Are Officials Hiding About Fukushima?
By Alex Roslin
“After the Chernobyl nuclear disaster in 1986, Soviet officials were vilified for hiding the impacts from the public. But when Japan’s Fukushima nuclear accident took place last March, public officials in Japan and Canada alike jumped straight into Chernobyl-style damage-control mode, dismissing any worries about impacts. Now evidence has emerged that the radiation in Canada was worse than Canadian officials ever let on. A Health Canada monitoring station in Calgary detected radioactive material in rainwater that exceeded Canadian guidelines during the month of March, according to Health Canada data obtained by the Georgia Straight.” […]

October 1, 2011 Wall Street Journal: Japan Discovers Plutonium Far From Crippled Nuclear Reactor
“[…]the latest discovery is a potentially disturbing turn, as it shows that people relatively far from the plant could be exposed to more dangerous elements than had been previously disclosed.
While neither plutonium nor strontium emit powerful gamma rays like cesium and iodine, both deposit in the body, strontium in the bones, plutonium in the bones and lungs and can cause cancer of leukemia once inhaled or ingested.
Both isotopes also have long half lives: it takes about 29 years for some forms of strontium to reduce by half, while plutonium isotopes have half-lives ranging from 88 years to over 24,000 years.
That makes them highly toxic in the body as they continue to emit alpha rays, and immensely difficult to get rid of in the environment.” source: http://online.wsj.com/article/SB10001424052970204226204576604013365441594.html

Meanwhile, the ministry said it had detected radioactive strontium-89 in nearly half of the locations inspected, including Shirakawa, about 79 kilometers from the nuclear plant. Because the half life of strontium-89 is only about 50 days, the ministry concluded that all the findings of the radioactive substance were linked to the Fukushima nuclear power plant. Namie registered the highest level of radiation, with 22,000 becquerels per one square meter of soil. [….]”

September 29, 2011 Wall Street Journal: Japan Failed to Hand Out Radiation Pills
[…] In interviews with The Wall Street Journal, several national and local government officials and advisers […] cited an abrupt move by the government shortly after the accident, when local officials raised sharply the level of radiation exposure that would qualify an individual for iodine pills […]
According to official disaster manuals written before the accident, anyone who showed radiation readings of 13,000 counts per minute […] was to be given KI pills […]
On March 14, Fukushima prefecture raised that cutoff to 100,000 cpm. […] The World Health Organization advocates [1,300 cpm] for giving the medication to children. “When they told us they wanted to raise the screening level, we instantly knew we had a serious level of contamination […] They were implicitly telling us they had more people than they could handle logistically, amid the shortage of water, clothing and manpower.” -Gen Suzuki, a physician specializing in radiation research and adviser to Japan’s Nuclear Safety Commission
Gauges on radiation monitors set for 13,000 cpm going off repeatedly: “It was very clear the previous level of 13,000 cpm wouldn’t work […] We discussed how the staff should turn off alarm sounds and refrain from wearing protective suits and face masks in order not to fan worries among residents.” -Naoki Matsuda, a professor of radiation biology at Nagasaki University and an adviser to the Fukushima prefecture government…

Sept. 28, 2011 The New York Times: Fukushima’s Contamination Produces Some Surprises at Sea
Six months after the accident at Fukushima Daiichi, the news flow from the stricken nuclear power plant has slowed, but scientific studies of radioactive material in the ocean are just beginning to bear fruit.
The word from the land is bad enough. As my colleague Hiroko Tabuchi reported on Saturday, Japanese officials have detected elevated radiation levels in rice near the crippled reactors. Worrying radiation levels had already been detected in beef, milk, spinach and tea leaves, leading to recalls and bans on shipments.
Off the coast, the early results indicate that very large amounts of radioactive materials were released, and may still be leaking, and that rather than being spread through the whole ocean, currents are keeping a lot of the material concentrated […]

Sept. 18, 2011 Aljazeera: Experts say Fukushima “worse” than Chernobyl
Experts estimate the radiation leaked from Fukushima nuclear plant will exceed that of Chernobyl:
Sea radiation three times higher than thought
The total amount of radioactive substances released into the sea as a result of the crisis at the Fukushima No. 1 nuclear power plant is believed to have been three times the initial estimate by the plant’s operator, according to the Japan Atomic Energy Agency.
A team led by senior researcher Takuya Kobayashi estimated the actual quantity at 15,000 terabecquerels, including substances in polluted water and substances released into the air that eventually fell into the sea. Tera means one trillion.
The figure is more than triple the estimate by Tokyo Electric Power Co. Also, the new estimate does not include cesium-134, meaning the actual total could be even larger.
The research team will announce its findings at a conference of the Atomic Energy Society of Japan scheduled to start in Kitakyushu on Sept. 19.
TEPCO’s calculation was based on the premise that polluted water containing high levels of radioactive substances was only released into the sea from April 1 to 6.
TEPCO estimated a total of 4,700 terabecquerels of radioactive substances–iodine-131, cesium-134 and cesium-137–leaked into the sea during that period.
Based on the density of radioactive materials near the nuclear plant’s water-intake facility, Kobayashi’s team calculated backward to the March 21 to April 30 period. Radioactive substances were first detected in the sea on March 21.
The team simulated the proliferation of the substances in the ocean based on its new estimate and confirmed that the results matched data from the sea near the nuclear plant. (Sep. 10, 2011) http://www.yomiuri.co.jp/dy/national/T110909005415.htm
Radiation expert says outcome of nuke crisis hard to predict, warns of further dangers
As a radiation metrology and nuclear safety expert at Kyoto University’s Research Reactor Institute, Hiroaki Koide has been critical of how the government and Tokyo Electric Power Co. (TEPCO) have handled the nuclear disaster at the Fukushima No. 1 nuclear plant. Below, he shares what he thinks may happen in the coming weeks, months and years.
The nuclear disaster is ongoing. Immediately after the crisis first began to unfold, I thought that we’d see a definitive outcome within a week. However, with radioactive materials yet to be contained, we’ve remained in the unsettling state of not knowing how things are going to turn out.
Without accurate information about what’s happening inside the reactors, there’s a need to consider various scenarios. At present, I believe that there is a possibility that massive amounts of radioactive materials will be released into the environment again.
At the No. 1 reactor, there’s a chance that melted fuel has burned through the bottom of the pressure vessel, the containment vessel and the floor of the reactor building, and has sunk into the ground. From there, radioactive materials may be seeping into the ocean and groundwater (…). See full article at http://mdn.mainichi.jp/perspectives/news/20110909p2a00m0na016000c.html

Fukushima Will Be Radiating Everyone for Centuries

Australia’s CBS exposed the “unspeakable” realities of the Japanese catastrophe in its 60 Minutes program Sunday night during which leading nuclear scientist Dr. Michio Kaku said radiation from Fukushima will impact of all of humanity. The nuclear energy power industry violation of the right to health is apparent throughout the new Australian report.
“In fact the whole world will be exposed from the radiation from Fukushima,” Dr. Kaku told CBS reporter Liz Hayes.
“We are already getting radiation from Fukushima,” Dr. Kaku said.
Just as Australia’s SBS exposed in depth the reality of the 2010 BP Gulf of Mexico catastrophe unlike any U.S. mainstream news station, Sunday, Australia’s CBS has now exposed in depth the Fukushima catastrophe.
“The Fukushima crisis is far from over. The crippled nuclear power plant is still leaking; and, judging from Chernobyl, recovery will not be measured in years, more like centuries,” reported the Australian presenter Liz Hayes.

TOKYO — Japan’s government estimates the amount of radioactive cesium-137 released by the Fukushima nuclear disaster so far is equal to that of 168 Hiroshima bombs
Tatsuhiko Kodama, head of the University of Tokyo Radioisotope Center: “By our estimates, the radioactive material released from Fukushima No. 1 Nuclear Power Plant, in uranium equivalents, amounts to 20 times the radiation released by the atomic bombing of Hiroshima. What’s more, the radiation will decrease at a much slower rate than after the A-bomb. When the amount of radiation is small, it’s enough to consider on-the-spot radiation. But when the total volume is huge, we have to think about how the particles will disperse. This happens in a non-linear manner, which is very difficult to calculate scientifically, because concentration is apt to occur in unpredictable locations. This will keep happening, such as when feed-hay for cattle was contaminated by cesium, and when contamination was found in tea and leaf mulch.”
Dr. Kodama completed Medical School at the University of Tokyo and became an internist doing both clinical and research work. Since 1996, he has been a professor of Systems Biology and Medicine at the University of Tokyo’s Research Center for Advanced Science and Technology, and in 2011 took on the additional job of head of the university’s Radioisotope Research Center.

Radiation tests urged for sockeye salmon, Georgia Straight (Vancouver) by Carlito Pablo, August 18, 2011:
“Marine biologist Alexandra Morton sees a need to test returning sockeye salmon for radiation from Japan’s Fukushima nuclear disaster.
“There was a large release of radioactive material in the water and in the air,” Morton told the Straight in a phone interview from her home on Malcolm Island. “I suspect that this generation of sockeye were out of the way, probably on their way home. But my sense of this is we need to test everywhere we can. As soon as I heard about this, I covered my gardens. I suspect that government doesn’t know how to deal with this, and in the face of it they just don’t want us to know.” […]
“Ernie Crey, fisheries advisor to the Sto:lo Tribal Council, agrees with Morton. “I think it’s a practical idea,” Crey told the Straight by phone. Asked if the returning fish are safe, he said: “I don’t know. This is a good question.”
However, Crey doesn’t expect the federal government to go ahead and test salmon for radiation. “That’s not something DFO [Fisheries and Oceans Canada] is going to voluntarily do or Health Canada or Environment Canada,” he said. […]

Revealed: British government’s plan to play down Fukushima
British government officials approached nuclear companies to draw up a co-ordinated public relations strategy to play down the Fukushima nuclear accident just two days after the earthquake and tsunami in Japan and before the extent of the radiation leak was known.
Internal emails seen by the Guardian show how the business and energy departments worked closely behind the scenes with the multinational companies EDF Energy, Areva and Westinghouse to try to ensure the accident did not derail their plans for a new generation of nuclear stations in the UK.
