An alarm was triggered at a onetime nuclear fuel manufacturing facility Wednesday after radioactive substances leaked from materials that were being transferred at a facility operated by the Japan Atomic Energy Agency (JAEA) in Tokai, Ibaraki Prefecture, officials with the company said.
All nine of the workers who were in the room when the radiation leak occurred were cleared with no ill affects to their health, JAEA official Shinichi Nishikawa told a news conference.
Sensors outside the facility, called the Nuclear Fuel Cycle Engineering Laboratories, did not record abnormal radiation levels, public broadcaster NHK reported.
Officials later told the news conference that they would begin processing the site as soon as possible to determine how much radioactive material had been leaked and if it was still leaking.
The warning alarm that detects radioactive materials went off at around 2:30 p.m. as workers were removing radioactive materials — which were contained in a plastic bag — from sealed-up equipment that had been used for experiments.
