Tepco Robots Find High Radiation Levels in Reactor Buildings

Robots sent into three buildings at Japan’s crippled Fukushima Dai-Ichi nuclear station detected radiation too toxic for humans after the plant operator set out a plan to end the crisis in six to nine months.

Measurements show one hour inside the No. 3 reactor building would expose humans to more than one-fifth of the radiation Japan has said is the most workers can endure in a year, the atomic safety agency said yesterday. The buildings were damaged by explosions in the days after a magnitude-9 quake and tsunami on March 11 knocked out cooling equipment, sparking the worst nuclear disaster since Chernobyl in 1986.
