Radioactive cesium detected in seawater

Radioactive cesium has been detected in seawater outside the port of the damaged Fukushima Daiichi nuclear power plant.

One-point-four becquerels per liter of cesium-137 was found in the sample. This is the first time that the radioactive material has been detected in seawater taken at that spot.

TEPCO officials say the radiation level is lower than the safety standard for drinking water set by the World Health Organization, which is 10 becquerels per liter.
