Factbox: What Tepco Aims To Achieve At Its Crippled Nuclear
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
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.
The worker fell ill 50 minutes after starting work at 6:00
a.m. on Saturday (2100 GMT on Friday) and brought to the
plant's medical room unconscious.
He was later moved to a nearby hospital and confirmed dead,
a Tokyo Electric spokesman said.

"I would like to spend my energy to improve working
conditions. Many people told us working environment (at the
plant) is way too bad," Hosono told a news conference.
The magnitude 9.0 earthquake and tsunami on March 11
triggered cooling system malfunctions at the plant, and
caused radiation to leak into the atmosphere and the ocean.
Engineers are still struggling to bring the plant under
control. Two Tokyo Electric employees went missing while
patrolling the plant soon after the quake and were later
