A slight excess of the norms of radiocaesium in fungi found in the prefectures of Aomori, Nagano and Shizuoka, deleted a few hundred kilometers from the nuclear power plant emergency, "Fukushima-1", said on Monday, the newspaper "Asahi".
While scientists can not explain the reasons why the six months after the accident (last fall), radioactive cesium was detected only in mushrooms from Fukushima prefecture, and this year, when the accident took place more than a year and a half, the radionuclides were found in mushrooms from distant from Fukushima prefectures. Excess weight, which is 100 for fungi becquerels per kilogram detected even at a distance of 350 kilometers from the nuclear power plant accident — up to 120 becquerels per kilogram.
Administration of these prefectures have banned the consumption of mushrooms and their implementation on the market.
The accident at the nuclear power plant "Fukushima-1" occurred after the most powerful earthquake in northeastern Japan March 11, 2011. Following the tremors of magnitude 9.0 on the shore came the 14-meter high tsunami which flooded four of the six reactors and knocked out reactor cooling system, which led to a series of hydrogen explosions, molten core.
The accident was the largest in 25 years after the Chernobyl disaster. There have been numerous leaks of radiation into the atmosphere and sea water. From the area within 20 kilometers of the plant were evacuated 140,000 people. Most of them are still living in temporary housing. A number of areas of high levels of contamination is expected to be declared uninhabitable. Complete elimination of the accident, including the dismantling of the reactors, will take about 40 years.
