A French independent radioactivity watchdog has found radiation in Fukushima Prefecture 60 times higher than the annual reference level for ordinary people recommended by an international commission.
Bruno Chareyron, director of the research institute CRIIRAD, briefed reporters in Tokyo on Wednesday on the results of its survey of the air in Fukushima Prefecture.
The measurements and calculations found an annualized amount of 60 millisieverts at a farm in Iitate Village in the prefecture.
The level is 60 times higher than the annual limit for ordinary people, except for radiation workers, of 1 millisievert, recommended by the International Commission on Radiological Protection.
The researchers also found high radiation levels in Fukushima City. At some places in the city, the levels of radioactivity were 7 to 9 millisieverts a year.
Chareyron urged Japan to increase the number of monitoring spots so that it can provide the public with detailed information on the negative effects of the radiation caused by the troubled Fukushima Daiichi plant.
The one-week survey from May 24th was conducted in cooperation with a Japanese nongovernmental organization.
