TEPCO has released partial results of a marine study of fish and shellfish in the 20 km body of water around the Fukushima Daiichi Nuclear Power Plant.  TEPCO released the Cesium 134 and Cesium 137 levels of 2 samples taken, the highest concentration of Cs-137 peaked at 1100 Bq/kg in two samples.  Cs-134 peaked at 840 bq/kg.

The highest levels were recorded close the shore, both north and south of the nuclear power station.  The highest levels were detected in the most southern sample taken with 840 Bq/kg of Cs-134 and 1100 Bq/kg of Cs-137.
