In a recent post in the Kyodo News there is a report that since the beginning of the disaster at Fukushima there has been a release of
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.
It is hard to imagine the studies that they did to determine that releases of 22 trillion Becquerels annually is safe. This works out to 750,000 Becquerels per second. This is distributed through the whole sample of water, not just a liter.
