Ministry of Education, plutonium radioactive material apparently diffused in the nuclear power plant disaster Fukushima Daiichi Tokyo Electric Power Company, the city Futaba Fukushima off-site nuclear power plants, were detected in soil in place a total of six villages allegedly towns and Namie revealed that 30 days.
The government has detected plutonium apparently from the crippled Fukushima Daiichi power plant outside the compound of the plant for the first time, science ministry officials said Friday.
The plutonium was detected at six locations in Fukushima Prefecture, including Iitate village around 45 kilometers northwest of the Fukushima complex
Was detected is likely to have been generated in the reactor, plutonium 238. The maximum concentration of 4 becquerels per square meter of the city Namie.
The radioactive substance may have been carried by vapor or fine particles from the nuclear plant, said an official of Tokyo Electric Power Co., the operator of the plant.
Plutonium has been already detected in the plant’s compound, some 220 kilometres from Tokyo.
The highest density of plutonium-239 and 240 — 4.0 becquerels per square metre — was registered in a town some 30 kilometres from the plant, the ministry said.
In a village 45 kilometres away, the reading was 0.82 becquerels per square metre.
Plutonium has accumulated in the country was falling nuclear test in the atmosphere of the past 10 years before the accident (1999 – 2008) the maximum concentration of 238 found in the study of 8 Bq same concentration of this was half that.
