Huge leak of tritium feared in Fukushima | The Japan Times
Tokyo Electric Power Co. said Friday that an estimated 20 trillion to 40 trillion becquerels of tritium from the Fukushima No. 1 nuclear plant may have flowed into the Pacific Ocean since May 2011.
The utility reported the estimate Friday to the Nuclear Regulation Authority after recently admitting that toxic water from the emergency cooling system set up after the nuclear crisis began on March 11, 2011, is leaking into the sea.
