Twenty three workers were exposed to low levels of radiation after a leak at Chubu Electric Power Co.'s Hamaoka nuclear plant in central Japan, the company said on Wednesday.
The amount of radiation from the leak of tainted water at the No 3 reactor was minimal and not enough to harm the workers' health, the company said.
Operations at the plant, in the Shizuoka Prefecture, southwest of Tokyo, have not been affected.
The cause of the leak, which saw 53 liters of water contaminated by more than 300 times radiation the amount permitted, is being investigated.
