4 researchers exposed to radiation at Tokaimura lab

TOKYO — Four researchers were exposed to radiation in an accident at a nuclear physics laboratory this week, officials said Saturday.

The accident occurred on Thursday at a laboratory in Tokaimura, Ibrakai Prefecture, 120 kilometers northeast of Tokyo, the Japan Atomic Energy Agency (JAEA) said.

The researchers were carrying out an experiment to generate particles by firing a proton beam at gold when the accident happened, it said.

There was no widespread radiation leak and none of the researchers required medical attention.

The four researchers were exposed to up to 1.6 millisieverts of radiation, the agency said.
