Abstract

Based on the analysis of data from contaminated water, the concentration of 137Cs in radioactive waste such as used cesium adsorption vessels and sludge generated from the Cesium Adsorption Device and Second Cesium Adsorption Device and from the Decontamination Device, which were operating or suspended as a part of the contaminated water treatment system at the Fukushima Daiichi nuclear power station was calculated. An estimate is made of the total amount of 137Cs recovered by decontamination from 28 June, 2011 to 12 August, 2014.
