It is endangered for more than 24,000 years enormously in half-life that plutonium element of Fukushima nuclear power station is let out
In Fukushima first nuclear power station of Japan, it is not that all aircrews use the similar nuclear fuel. The reactor while taking place in heavy earthquake is still in 3 aircrews of operation, what the aircrew used is enriched uranium on the 1st and the 2nd, but the aircrew hides danger than unconventional nuclear fuel 2 million times higher, formed after plutonium element is mixed with uranium element of enriched uranium on the 3rd, once the fuel let out, form, influence while being long-term to environment; After the human body sucks, be exposed to the open air in radiation constantly, the chance of contracting cancer will be heightened. The nuclear fuel in the aircrew No. 3, include 88 tons of nuclear fuel formed after plutonium element and uranium element are mixed, because its radioactive element is taller in density, can rise to higher temperature, close the nuclear power station, will cool more surplus heat soon. Such mixed fuel is military the core out of service to make into, more than 20 nuclear power stations are being used at least at present in the global various countries. Contain plutonium in the nuclear waste material that and the general light water reactor produces. Plutonium has isotope of six to seven kinds, the most stable one is plutonium - 244, 80 million years of half-life, and the one that use most now, easy fission plutonium 239, once release the natural environment, half-life is as long as 24,000 years, in other words, should go through 24,000 years, radioactivity will be reduced by half. And is found plutonium 240 and plutonium 238 of the soil of first nuclear power station in Fukushima too, half-life is up to 6560 and 87.7 years respectively. Plutonium element toxicity is very strong, especially sucked from the respiratory tract by the human body, the reason is that the lung is very sensitive to radiation. If eaten, the injury that plutonium element causes will be relatively low, but still can reach each organ, stay in the body permanently, make tissue exposed to the open air in carcinogenic radiation. Plutonium will release the alpha particle with high-energy in the human body, act as the alpha particle and strike the tissue, enough to damage DNA of cells, thus cause carcinogenic mutation. Enter behind the human body, the intersection of plutonium and speed that element is list very slow, still for more than 200 years half-life in human body.
