Blessing island detects first outside the first nuclear power plant a plutonium

Xinhua net Tokyo on September 30 report (reporter La Jianzhong) province of science of Japanese language department says 30 days, detect in the soil of 6 places such as the village of restaurant of blessing island county that in blessing island northwest of the first nuclear power plant makes an appointment with 45 kilometers gave plutonium. This is Japanese government is in first the plutonium that blessing island discovers to nuclear leak accident arises outside the site of factory of the first nuclear power plant. Nevertheless province of language department science says, detect the plutonium concentration that give is very low, the radiate of generation is very small also. The half-life of plutonium is very long, can wait through breath enter human body, have the intense effect that cause cancer. Because plutonium is very heavy, ever was thought to fly to far hard before this. Give plutonium to detecting this, explanation of Tokyo power company says, the first nuclear power plant produces blessing island nuclear leak postaccident, plutonium adheres to likely in vapor perhaps fly on particle come loose far. Came in June in July, province of language department science collected blessing island the soil that 100 ground inside 80 kilometers limits nod radius of the first nuclear power plant, whether does investigation contain the radioactivity material such as plutonium among them. Detecting in 6 places that give plutonium, farthermost from nuclear power plant place is located in restaurant village, the distance makes an appointment with 45 kilometers, plutonium - 238 achieve every square metre 0.82 Bei Kele Er, plutonium - 239 with plutonium - 240 aggregate achieve every square metre 2.5 Bei Kele Er. Province of language department science is right still Strontium of material of another kind of radioactivity undertook investigating. In 100 places of investigation, 10 several places detect the Strontium that went out to come out according to considering as an accident leak, among them some places make an appointment with 80 kilometers from nuclear power plant, this proof Strontium also diffused inside wide range.
