TOKYO - A worker at Japan's tsunami-crippled Fukushima Daiichi nuclear power plant died on Saturday, plant operator Tokyo Electric Power Co said, bringing the death toll at the complex to three since a massive earthquake and tsunami in March.
The cause of the death was unknown. The man, in his 60s, was employed by one of Tokyo Electric's contractors and started working at the plant on Friday. He was exposed to 0.17 millisieverts of radiation on Saturday, Tokyo Electric said.
The Japanese government's maximum level of exposure for male workers at the plant is 250 millisieverts for the duration of the effort to bring it under control.
