Nature - the Magazine, copies Words of Pro-Nuke Interests

Nature, the reputed science magazine, has been finally "bought" by the pro-nuke interest groups and begun to speak as if the disasters from radiation which we have been learning through even real friends do not exist in Japan.  Officially (meaning according to the mainstream media), in Japan, nobody has died in Fukushima for radiation over the past 14 months after the over-Chernobyl level accident occurred, and the Government acted even more irresponsibly than the then-USSR.

They even prepared the video to show Fukushima Daiichi Nuclear Power Plant as if everything is going well toward settlement.  The tone of the narration sounds as rhythmical as NHK newscasters.  The major media worldwide (even anti-American regions) are obviously under control of the huge amount of money connected to the nuclear industry.

We can check real Fukushima-Daiichi workers' tweets everyday, and our concern regarding the great probability of the hopeless explosion of Unit 4 Fuel Pool (containing 1535 fuel rods; plus over 10 thousand in the premises) has never been wiped out.  Those workers are not virtual, but real as our trusted independent web journalist, Yasumi Iwakami interviewed them live.

According to Arnie Gundersen, the greatest danger has always been Unit 4 for this reason, and it is impossible that the US Government is ignorant about it.  The reason operation of Hamaoka Nuclear Power Plant was suspended by the former prime minister Naoto Kan so easily is sait to be the pressure from the US as it threatens logistics of their army with its base in Yokosuka, too close to Hamaoka.

Anyway, here's the copy of unbelievable Nature's article.  I wonder how long those money-obsessed insane people control the world.  They are even endangering their own planet, let alone their own or family's lives.


Fukushima’s doses tallied

Studies indicate minimal health risks from radiation in the aftermath of Japan’s nuclear disaster.

Around 170 of Fukushima’s workers have a slightly elevated risk of cancer due to their radiation exposure.

Few people will develop cancer as a consequence of being exposed to the radioactive material that spewed from Japan’s Fukushima Daiichi nuclear power plant last year — and those who do will never know for sure what caused their disease. These conclusions are based on two comprehensive, independent assessments of the radiation doses received by Japanese citizens, as well as by the thousands of workers who battled to bring the shattered nuclear reactors under control.
The first report, seen exclusively by Nature, was produced by a subcommittee of the United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR) in Vienna, and covers a wide swathe of issues related to all aspects of the accident. The second, a draft of which has been seen by Nature, comes from the World Health Organization (WHO) in Geneva, Switzerland, and estimates doses received by the general public in the first year after the accident. Both reports will be discussed at UNSCEAR’s annual meeting in Vienna this week.
The UNSCEAR committee’s analyses show that 167 workers at the plant received radiation doses that slightly raise their risk of developing cancer. The general public was largely protected by being promptly evacuated, although the WHO report does find that some civilians’ exposure exceeded the government’s guidelines. “If there’s a health risk, it’s with the highly exposed workers,” says Wolfgang Weiss, the chair of UNSCEAR. Even for these workers, future cancers may never be directly tied to the accident, owing to the small number of people involved and the high background rates of cancer in developed countries such as Japan.
Scientists involved in producing the UNSCEAR report hope that their independent summary of the best available data could help to dispel some of the fear about fallout that has grown over the past year (seeNature 483, 138–140; 2012). As well as providing a preliminary assessment of workers’ exposure, the UNSCEAR report concludes that the Japanese government’s estimate of the radiation released was correct to within a factor of ten, and that further study is needed to fully understand the impacts of the accident on plants, animals and marine life near the power station. When a final version of the report is approved by the full UNSCEAR committee next year, it should provide a useful baseline for future studies.
The Fukushima crisis began on 11 March 2011, when a magnitude-9.0 earthquake triggered a tsunami off the coast of Japan. A 14-metre wave flooded four of the six reactors at the Fukushima Daiichi plant, knocking out emergency cooling systems and leading to meltdowns and explosions that released radioactivity into the air and ocean. In the year since the accident, the plant has been stabilized, and radioactive emissions have largely stopped.
From last autumn, UNSCEAR has been reviewing all the available data on Fukushima’s radiation — just as it did to produce what was then the definitive report on the 1986 Chernobyl nuclear accident. In particular, it scoured anonymized medical data for 20,115 workers and contractors employed by the Tokyo Electric Power Company, which runs the plant. It found that 146 employees and 21 contractors received a dose of more than 100 millisieverts (mSv), the level at which there is an acknowledged slight increase in cancer risk. Six workers received more than the 250 mSv allowed by Japanese law for front-line emergency workers, and two operators in the control rooms for reactor units 3 and 4 received doses above 600 mSv, because they had not taken potassium iodide tablets to help prevent their bodies from absorbing radio­active iodine-131 (see ‘In the zone’). So far, neither operator seems to have suffered ill effects as a result of their exposure.

Most of the workers who received high doses were exposed in the early days of the crisis. In those first hours, they were huddled in darkened control rooms, while small teams made forays inside the reactor buildings to survey the damage and manually operate valves and other equipment. Often, they did not know how much radiation was present — the report says that an automated system designed to monitor their radiation levels was not operating properly. By mid-April, basic access control and monitoring had been restored on the site.
Experts agree that there is unlikely to be a detectable rise in thyroid cancer or leukaemia, the two cancers most likely to result from the accident. “There may be some increase in cancer risk that may not be detectable statistically,” says Kiyohiko Mabuchi, who heads Chernobyl studies at the National Cancer Institute in Rockville, Maryland. In Chernobyl, where clean-up workers were exposed to much higher doses, 0.1% of the 110,000 workers surveyed have so far developed leukaemia, although not all of those cases resulted from the accident.
The risk to the roughly 140,000 civilians who had been living within a few tens of kilometres of the plant seems even lower. Because detailed radiation measurements were un­available at the time of the accident, the WHO estimated doses to the public, including radiation exposure from inhalation, ingestion and fallout. The agency concludes that most residents of Fukushima and neighbouring Japanese prefectures received a dose below 10 mSv. Residents of Namie town and Iitate village, two areas that were not evacuated until months after the accident, received 10–50 mSv. The government aims to keep public exposure from the accident below 20 mSv per year, but in the longer term it wants to decontaminate the region so that residents will receive no more than 1 mSv per year from the accident.
The WHO’s calculations are consistent with several health surveys conducted by Japanese scientists, which found civilian doses at or below the 1–15-mSv range, even among people living near the plant. One worrying exception is that infants in Namie town may have been exposed to enough iodine-131 to receive an estimated thyroid dose of 100–200 mSv, raising their risk of thyroid cancer. But data collected from 1,080 children in the region found that none had received a thyroid dose greater than 50 mSv. Chernobyl’s main cancer legacy in children was thyroid cancer.

Fearful and angry

The large population involved could mean that the eventual number of radiation-induced cancers among the public will actually be higher than among workers, even though the risk to each individual civilian is tiny, says David Brenner, a radiologist at Columbia University in New York city. But he doubts a direct link will ever be definitively made. Under normal circumstances, “40% of everybody will get cancer”, he says. “It doesn’t seem to me that it’s possible to do an epidemiological study that will see an increased risk.” Still, it may be valuable to conduct studies to reassure the population that they are not being misled, he adds.
A far greater health risk may come from the psychological stress created by the earthquake, tsunami and nuclear disaster. After Chernobyl, evacuees were more likely to experience post-traumatic stress disorder (PTSD) than the population as a whole, according to Evelyn Bromet, a psychiatric epidemiologist at the State University of New York, Stony Brook. The risk may be even greater at Fukushima. “I’ve never seen PTSD questionnaires like this,” she says of a survey being conducted by Fukushima Medical University. People are “utterly fearful and deeply angry. There’s nobody that they trust any more for information.”
Overall, the reports do lend credibility to the Japanese government’s actions immediately after the accident. Shunichi Yamashita, a researcher at Fukushima Medical University who is heading one local health survey, hopes that the findings will help to reduce stress among victims of the accident. But they may not be enough to rebuild trust between the government and local residents. Tatsuhiko Kodama, head of the radioisotope centre at the University of Tokyo and an outspoken critic of the government, questions the reports’ value. “I think international organizations should stop making hasty reports based on very short visits to Japan that don’t allow them to see what is happening locally,” he says.
UNSCEAR’s working committee of roughly 70 scientists still has much to do before the final report is completed. Committee members will continue to independently validate sources of data from the accident and work on models of the flow of radio­isotopes from the reactors into the environment. For the workers, “individual medical follow-up is more important than the statistical follow-up”, Weiss says. “People want to know whether what we say is true.”


Sooner or later the magazine and the author will be recorded for what they have done.  We won't remain stupid and naive enough to be deceived after learning so much of history of lies about Hiroshima, about Nagasaki, and about Chernobyl.
