Fukushima nuclear power station finds plutonium is let out Do not deal with and have endless trouble in time
No matter how much plutonium let out is, it is very troublesome to deal with. Should take the fuel away in time excellently now, otherwise have endless trouble Beijing time before dawn on March 29, it is verified that International Atomic Energy Agency releases the announcement, Japan finds micro- radioactive element plutonium in the soil sample near Fukushima first nuclear power station. The announcement of International Atomic Energy Agency has not explained which kind of plutonium Japan detects, and common isotope plutonium - 239 in nuclear power station reactor, reaches more than 20,000 years in half-life, namely half its happen, decay and the intersection of radiation and risk reduce half the time, need more than 20,000 years. Because the toxicity of plutonium is great, half-life is relatively long, this news caused people worrying more to Fukushima nuclear power station. The academy of sciences of Chinese atomic energy takes care of the loyal luxuriant researcher to tell the new reporter of the wealth, plutonium is that the nuclear fuel must emerge in the course of reacting, have already measured the radioactive iodine before this, has proved the damage takes place in the excellent outer cover of fuel, this means that leaking must contain plutonium in the material. On the other hand, plutonium compares with iodine, less liquid, the iodine is volatile, to the air middle-distance race, and plutonium is that the advanced person entries into water, enter soil again, it is just a time question to measure to plutonium. Protect wishing with medical science of nuclear safety Chinese researchers of the people say to the new reporter of the wealth in radiation of Center for Disease Prevention and Control of China, plutonium is a fissile product, it is not natural, it is artificial. But he says, though plutonium has a radioactive one, half-life is very long, but there is very few quantity measured in the environment at present, what danger does it will produce to the human body. In addition, already shutdown because of the reactor, there should not be a large amount of plutonium to let out. Certainly, Gu ZhongMao points out, no matter how much plutonium that lets out is, it is very troublesome to deal with. Japan is still devoted to cooling in situ at present, another scheme is to pile and deal with one like that as cutting to the promise Pele, but its cost and cost are extremely high. "Leakage of plutonium begin just now, should wonderful to take away fuel in time. " Gu ZhongMao says, " if adopt finally one piles and deals with but not takes away plutonium, plutonium will still pollute the groundwater, have endless trouble. " International Atomic Energy Agency claims, micro- plutonium appears in the soil, it is not a rare thing, because plutonium will float and fall in the soil in all parts of the world after the nuclear test. However, this organization quotes Tokyo Utilities Electric Co. to say, according to composition of isotope found in the soil near Fukushima first nuclear power station plutonium, should let out from the nuclear power station reactor. And the content of plutonium in its soil, has not exceeded this natural bottom level that Japanese Ministry of Education has monitored in the past 30 years yet at present.
