Fukushima pollution much larger says French report: Japan

French researchers say the amount of radioactive cesium that has leaked from the crippled Fukushima Daiichi nuclear power plant into the ocean is 20 times larger than the plant operator estimated.

The French government's nuclear research institute, IRSN, released its contamination report on Saturday.

It calculates that 27.1 thousand terabecquerels of radioactive cesium 137 had leaked into the ocean as of the middle of July. The largest amount was released by early April from a pit at the Number 2 reactor and other plant facilities.

The French institute says the amount is about 20 times the estimate made by Tokyo Electric Power Company.

The report says the nuclear accident caused significant water contamination, but radioactive substances will be dispersed by ocean currents.

Nevertheless, the institute is calling for ongoing testing of marine products as leakage from the nuclear facility continues to pollute the nearby ocean. source
