220 tons of highly radioactive water leaked and a part of it leaked to the sea

12/4/2011 11:30AM, a sub-contractor worker found highly radioactive water was leaking from water purifying system. It was from the water conversion section.

The worker reported that 45 tons of contaminated water leaked but potentially 220 tons of polluted water had leaked out.

It contains 45,000 Bq/L of cesium, which is 300 times much as some kind of a “safety limit”, and it contains 1 million times much strontium as some kind of a “safety limit”.

As to Strontium, Tepco does not announce the actual amont contained in the water.

The water purifying system can not filter out strontium, which is water soluble.

The tank contains over 10,000 tons in total.

The leaked water flowed into a gutter which is connected to the sea at 500 meters away.

They could not do anything more than put sandbags.

The leaked water is more contaminated than the water that Tepco leaked in April on purpose.

The surface emits 110 mSv/h of beta radiation, mostly from Strontium etc., and 1.8 mSv/h of gamma radiation, mostly from Cesium.
