The operator of the Fukushima Daiichi nuclear power plant says no radioactive cesium was detected in seawater around the No.3 reactor on Saturday. This was the first time the substance was not detected since the monitoring began.

Cesium levels around the No.2 reactor were down slightly from those detected on the previous day.

Tokyo Electric Power Company, or TEPCO, 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 recorded 0.077 becquerels of cesium-134 per cubic centimeter, which is 1.3 times higher than the government-set safety limit.

It also contained 0.075 becquerels of cesium-137, or 0.83 times the limit. Both figures were slightly down from the levels 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 has declined, and recently is leveling out.

Seawater sampled near the water intake of the No.3 reactor did not contain any cesium-134 or cesium-137.

No radioactive materials were found in seawater taken from 7 locations along the coast and offshore.
