Documenting the levels Of Radiation Release
Monday, May 2, 2011
Physicians for Social Responsibility, a U.S. nonprofit organization of medical experts, has condemned as “unconscionable” the Japanese government’s safety standards on radiation levels at elementary and junior high schools in nuclear disaster-stricken Fukushima Prefecture.
The PSR statement directly challenges Tokyo’s stance that it is safe for schoolchildren to use school playgrounds in the prefecture as long as the dose they are exposed to does not exceed 20 millisieverts over a year.
The PSR view is also in line with that voiced by Toshiso Kosako, who said Friday he would step down as an adviser to Prime Minister Naoto Kan on the Fukushima nuclear crisis in protest. The University of Tokyo professor urged the government to toughen guidelines on upper limits on radiation levels the education ministry recently announced for elementary school playgrounds in Fukushima.
The U.S. group said in a statement released Friday, “Any exposure, including exposure to naturally occurring background radiation, creates an increased risk of cancer.
“Children are much more vulnerable than adults to the effects of radiation, and fetuses are even more vulnerable,” it said.
The medical experts group is part of the International Physicians for the Prevention of Nuclear War, which won the 1985 Nobel Peace Prize.
“(Twenty millisieverts) for children exposes them to a 1 in 200 risk of getting cancer. And if they are exposed to this dose for two years, the risk is 1 in 100. There is no way that this level of exposure can be considered ‘safe’ for children,” the statement said.
This is a home video of measurements taken at multiple locations in Fukushima city for radiation contamination. Fukushima city is roughly 63 kilometers from the Fukushima Daiichi Nuclear Plant placing it outside of the exclusion zone. In some locations the measurements reach as high as 97 µSv/h. There Are NO Background Levels of Radioactive Cesium or Iodine both are man made substances emitted from nuclear fission reactors and increase the risk of cancer
The health ministry plans to scrap the annual radiation dose limit for nuclear power plant workers at normal times for the meantime to secure enough workers for maintenance and checkups of nuclear power plants other than the crisis-hit Fukushima power station, sources close to the matter said Wednesday.
A woman working at the crippled Fukushima nuclear plant was found to have been exposed to radiation of more than 3 times the legal safety limit.
The woman, in her 50s, showed no health problems in a medical checkup.
Her employer, Tokyo Electric Power Company, says the woman was in charge of managing disaster-related supplies and showing firefighters around the plant’s compound.
She worked at the plant for 11 days after the March 11th earthquake and tsunami, and was exposed to 17.55 millisieverts of radiation. The figure is more than 3 times the permissible amount for women, which is set at 5 millisieverts per 3 months.
The woman may have inhaled radioactive material when taking off protective gear, as internal exposure of 13.6 millisieverts accounted for much of the total.
The limit for workers at the Fukushima plant was raised from 100 to 250 millisieverts per year after the accident to cope with the emergency. But the limit for women was left unchanged due to their child-bearing possibilities.
Senior official of the Nuclear and Industrial Safety Agency, Hidehiko Nishiyama, told reporters it is very sorry that the woman was exposed to excessive radiation. It says it has already reprimanded TEPCO verbally, and plans to order it in writing to find out why this happened and take steps to prevent a recurrence.
