Fourteen workers treated radioactive water leaking at the crippled Fukushima No. 1 nuclear plant without wearing personal dosimeters as required, Tokyo Electric Power Co. said April 19.
The dosimeters, which are worn on a worker’s finger, measure and record the doses of beta rays, or high-speed electrons.
According to TEPCO, the 14 workers are employees of a partner company that engaged in the work from April 6. The leakage of radioactive water from underground storage tanks first came to light on April 5.
