The operator of the damaged Fukushima Daiichi nuclear plant says 2 workers believed to be contaminated with radiation took iodine tablets just once, 2 days after the quake.
The Tokyo Electric Power Company, or TEPCO, found that the pair may have been exposed to radiation exceeding the safety limit of 250 millisieverts set for emergency situations by the government.
TEPCO said the men, one in his 30s and the other in his 40s, worked in the control rooms of the Numbers 3 and 4 reactors after the accident.
Radiology experts who examined the workers have questioned whether the timing and level of iodine dosage was appropriate.
TEPCO says it is checking how often other workers took the tablets.
