10 million time radiation spike at reactor reported
Japan live blog: Radiation levels spike near damaged nuclear plant
[1:30 a.m. ET Sunday, 2:30 p.m. Sunday in Tokyo] Radiation levels in pooled water tested in the No. 2 nuclear reactor's turbine building at the Fukushima Daiichi power plant are 10 million times normal, a power company official said Sunday.
Japan's nuclear and industrial safety agency reports the surface water showed 1,000 millisieverts of radiation. By comparison, an individual in a developed country is naturally exposed to 3 millisieverts per year, though Japan's health ministry has set a 250 millisievert per year cumulative limit before workers must leave the plant.
