TOKYO, JAPAN - Two workers at Japan's crippled nuclear plant might have exceeded a radiation exposure limit amid concerns about the risks faced by the workers struggling to contain the crisis.

Tokyo Electric Power Co. said Monday the two control room
operators are being tested further and don't have immediate health
problems.

If exposures beyond the limit are confirmed, they would be the
first men to reach the government-set limit.

The government had eased its previous limit for men soon after
the earthquake and tsunami set off the crisis at the tsunami-hit
Fukushima Dai-ichi plant on March 11.

The two men were responsible for Unit 3 and 4 central control
rooms when the quake and tsunami knocked out the plant's power and cooling functions.
