170,000 Bq/Kg from the soil of storage reservoir in Fukushima
Tohoku Regional Agricultural Administration Office and Fukushima prefectural government conducted radiation measurement for the ground soil of 14 storage reservoirs in Fukushima from 3/26 to 4/6/2012. Sample is dried soil from ground of storage reservoir (5 ~ 7cm deep).
Cesium134 and 137 were measured from all of those samples.
