More radioactive water leaks into sea near stricken plant
2011/5/13

<snip> Checks on seawater outside a silt fence installed by TEPCO last month at an intake of the No. 3 reactor to stop contamination from spreading out to sea found 96 becquerels of iodine-131 per cubic centimeter, 2,400 times above safety standards, according to the utility. The silt fence is a plastic curtain hanging from floats and reaching near the sea bottom.

Inside the pit, the iodine-131 level was 3,400 becquerels per cubic centimeter, 85,000 times the permissible level.

Cesium-134 was measured at 37,000 becquerels per cubic centimeter, 620,000 times the safety limit.
