Japan:Cesium levels down in seawater near reactors 2, 3
Laaska News August 15,2011
The operator of the Fukushima Daiichi nuclear power plant says the density of radioactive cesium in seawater near the water intakes of the No.2 and 3 reactors was down on Saturday to about one tenth of the levels detected on the previous day.
Tokyo Electric Power Company monitors the concentration of radioactive substances in seawater near the water intakes of the plant and offshore.
Seawater collected near the water intake of the No.2 reactor on Saturday was found to contain 0.058 becquerels of cesium-134, or 0.97 times the government-set safety limit. It also contained 0.056 becquerels of cesium-137, or 0.62 times the limit. Both figures were around one tenth of the level found on the previous day.
In April, the level of cesium-137 in seawater near the water intake of the No.2 reactor was found to be 1.1 million times the safety limit. Since then, the density of the radioactive element has been declining, and recently it has fallen below the limit sometimes.
Seawater sampled near the water intake of the No.3 reactor on Saturday was found to contain 0.087 becquerels of cesium-134, or 1.5 times the safety limit. It also contained 0.09 becquerels of cesium-137, or about the same as the limit. Both figures were less than one tenth of the level found on the previous day.
Seawater taken from 6 spots offshore was found to contain no radioactive materials.
