The Japanese Nuclear and Industrial Safety Agency said Thursday there is no need at present to evacuate residents in a radiation-hit northeastern village despite a warning by the International Atomic Energy Agency.
The Japanese agency, under the aegis of the Ministry of Economy, Trade and Industry, calculated the radiation exposure level for residents in the village of Iitate, Fukushima Prefecture, using atmospheric radiation data gathered by the science ministry.
On the assumption that a person stays outdoors for eight hours, the radiation exposure level in the village came to 25 millisieverts, half the level requiring evacuation, according to officials of the agency.
The village is located 40 kilometers northwest of the Fukushima No. 1 nuclear power plant, which was damaged by the March 11 earthquake and tsunami, and is thus outside of the evacuation zone set by the government for areas within 20 kilometers from the plant.
Noting that radiation levels are gradually falling at some survey points, Hidehiko Nishiyama, an official at the nuclear safety agency, said that the exposure level calculated by the agency does not pose problems.
