JAPAN: Radioactive strontium leaked into the sea – TEPCO

The operator of the Fukushima Daiichi nuclear power plant says about 150 liters of radioactive contaminated water, containing radioactive strontium, has leaked into the sea.

The Tokyo Electric Power Company found on Sunday that massive amounts of radioactive water had leaked from a desalination device. It said that up to 300 liters of radioactive water leaked out from cracks in the foundation of the building which contains the device.

The company detected beta-ray emitting radioactive substances, including strontium, from a gutter near the building. The gutter drains into the Pacific Ocean.

TEPCO announced on Tuesday that it estimates about 150 liters of radioactive water reached the sea.
Radioactive strontium accumulates in the bones once inside a body due to its similar properties to calcium and releases radiation for a long time. One type of strontium — strontium 90 — has a half-life of 29 years.

TEPCO apologized for the leak. However the power company said that, judging from the amount released, it is likely to have almost no effect on the environment.
