– Plutonium measured from marine products fished offshore Fukushima (Fukushima Diary, June 26, 2012):
Plutonium 239+240 were measured from fish samples taken on 6/21/2011. They were preserved being frozen. Analysis was done by National institute of radiological sciences. Data about Plutonium 238 and 241 are not published.
They fished the fish offshore Onahama port, where is about 54km from Fukushima plants. (120 ~ 300m deep under sea.)
Because none of the other nuclides exceed the safety limit of food, they were probably distributed to the markets.
Dr. Helen Caldicott (Co-founder of Physicians for Social Responsibility):
You’ve bought the propaganda from the nuclear industry. They say it’s low-level radiation. That’s absolute rubbish. If you inhale a millionth of a gram of plutonium, the surrounding cells receive a very, very high dose. Most die within that area, because it’s an alpha emitter. The cells on the periphery remain viable. They mutate, and the regulatory genes are damaged. Years later, that person develops cancer. Now, that’s true for radioactive iodine, that goes to the thyroid; cesium-137, that goes to the brain and muscles; strontium-90 goes to bone, causing bone cancer and leukemia. It’s imperative … that you understand internal emitters and radiation, and it’s not low level to the cells that are exposed. Radiobiology is imperative to understand these days.”
