Amounts of radioactive cesium, Cs-137 and Cs-134, in 24 h urine of 37 children have been determined using an HP-Ge detector, in Fukushima Prefecture between February 2014 and March 2016. As comparisons, those of 25 children have been also measured who live in Western Japan from September 2016 to March 2017, and that of one child in Ibaraki Prefecture from April 2014 to January 2017. We have found the cesium concentrations in the more than 70% of urine samples from Fukushima Prefecture are in the ranges from 0.06 to 0.30 Bq/L. No radioactive cesium is observed in the samples from Western Japan, under the detection limit of 0.1 Bq/L. In the case of Ibaraki, the radioactivity keeps its value around 0.20 Bq/L during the inspection period, indicating the chronic ingestion of the radioactive cesium in his daily life.
