Fukushima Worker Dose Experience
 Two workers at the troubled Fukushima Daiichi nuclear power plant may have been exposed to high levels of radiation exceeding the safety limit set by the government. If confirmed, these are the first cases of radiation exposure since the health ministry raised the limit in March following the accident.

Two Workers
 2 workers are men. One is in his 30s and the other in his 40s. Both worked at the control rooms of the Number 3 and 4 reactors, and elsewhere, after the
accident broke out at the plant
 TEPCO said a test conducted at an institute last Monday found 9,760 becquerels and 7,690 becquerels of radioactive iodine-131 in the workers’ thyroids.
 This means they are likely suffering from internal radiation exposure after inhaling radioactive substances.

Worker Doses at Fukushima
The 2 contaminated workers have been exposed to external radiation of 74 and 89 millisieverts so far.
TEPCO said these combined readings suggest that the 2 may have been exposed to radiation levels exceeding the safety limit of 250 millisieverts set for emergency situations

Yet where are these reports in the public documents?
