Fukushima plant may have leaked huge amount of radioactive tritium

Tokyo Electric Power Co. said Friday that an estimated 20 trillion to 40 trillion becquerels of radioactive tritium may have flowed from the crippled Fukushima Daiichi nuclear power plant into the Pacific Ocean since May 2011.

The plant operator reported the estimate to the Nuclear Regulation Authority after recently admitting that toxic water, accumulating at the site since the nuclear crisis was triggered on March 11, 2011, is seeping into the sea.

TEPCO said the release is around the level allowed under safety regulations, which is 22 trillion becquerels annually, but acknowledged that it had not taken place in a controlled way.
