Exposure to radiation is obtained from the region has now reached 19 millisievert. Exactly one point below the safe limit set by the International Nuclear Safety Agency.
This was conveyed by the local government and reported by Reuters on Tuesday (13/12/2011).
Contained the greatest radiation exposure at Iitate city located about 40 kilometers northwest Fukushima nuclear power plants. Iitate city itself is outside the evacuation zone set by the government, namely as far as 20 kilometers.
The Government has asked local residents to leave town as soon as possible Iitate. But unfortunately it does not mention the exact number of people in the region.
According to calculations, residential areas that are within the evacuation zone had exposure to at least reach the level of 0.18 to 2.3 millisievert up to 4 months after the destructive earthquake and tsunami Fukushima nuclear power reactors.
But what is happening now is very far from the calculation. Therefore, radiation exposure has now reached levels of 0.84 to 19 millisievert, ranging from the region closest to the reactor until the area outside the evacuation zone.
"The research categorizes the population into 18 behavioral patterns based on exposure estimates. There are probably some people exposed to greater exposure. But long exposure to still be at around level 19, should not there any health risks," said a local official.
International Commission for Radiological Protection recommends that radiation exposure be kept below the level of 20 millisieverts per year.
The earthquake and tsunami that hit Japan in March have damaged nuclear reactor cooling systems at Daiichi, Fukushima nuclear power plants. Even this incident sparked radiaktif substances leak into the waters near the reactor. However, the report found radioactive investigation that extends to the sea does not pose a threat to humans or animals.
