An explosion Saturday at the Fukushima No. 1 power plant may have exposed 1-year-olds to more than 100 millisieverts of radiation — even outside the 30-km danger zone — a government computer simulation shows.
"There are some cases in which they could have received more than 100 millisieverts of radiation, even if they're outside the 30-km radius and in the event that they spent every day outdoors since the explosion at the Fukushima nuclear plant," Chief Cabinet Secretary Yukio Edano told a news conference.
Nuclear Safety Commission Chairman Haruki Madarame told reporters, "The figure represents the level that 1-year-olds would have received and accumulated in their thyroids by midnight Wednesday since the explosion."
