Tests have revealed that another worker at the troubled Fukushima Daiichi nuclear plant has been exposed to radiation doses exceeding 100 millisieverts. Before the accident in March, 100 millisieverts was the maximum radiation exposure permitted in an emergency situation.

Tokyo Electric Power Company, the operator of the plant, submitted a report to the heath ministry on Thursday. The utility checked the radiation exposure of about half of the 4,300 people who started working at the plant in April.

TEPCO says none of the workers has been exposed to doses exceeding the legal limit of 250 millisieverts set by the government for emergency situations.

But one worker was exposed to 111 millisieverts, while the readings for 9 other people were between 50 and 100 millisieverts.

The health ministry instructed the utility to promptly carry out tests on the remaining half of the workers and report back by July 13th.

TEPCO has nearly completed checking the people who were working at the plant in March. The checks found that 3 of them had been exposed to doses exceeding the 250-millisievert emergency limit, while 4 others were suspected to having surpassed that limit.

The limit radiation exposure was raised from 100 millisieverts to 250 millisieverts after the Fukushima accident to secure enough time for workers at the plant to bring the situation under control.
