Two Tokyo Electric Power Co. employees working at the stricken Fukushima No. 1 nuclear plant may have been exposed beyond the 250-millisievert limit set for the crisis, Tepco and the government said Monday.
The two men, one in his 30s and the other in his 40s, have been at the plant since the March 11 disasters triggered the crisis. Both may have a cumulative exposure of several hundred millisieverts, a company official said, while adding the two are "not at a stage that would require emergency medical treatment."
To cope with the country's worst nuclear plant crisis, the government raised the legal limit on the amount of radiation a worker can be exposed to in emergencies to 250 milliseiverts from 100 millisieverts.
