Another leak at Japanese nuclear power plant

Japan’s nuclear watchdog has detected an additional radioactive leak from the atomic power plant damaged in this week’s earthquake, Kyodo News agency reported today.

The report said the leak came from an exhaust vent in the Kashiwazaki-Kariwa plant in north-west Japan, but that the leak did not threaten the environment or public health.

The Nuclear and Industrial Safety Agency said it found radioactive iodine had leaked from the plant, which suffered several leaks and accidents in Monday’s quake in which nine people died.
