Abstract
Some 1300 people have been examined for internal contamination with radioactive cesium at
Fukushima CRMS with the AT1316 whole body counter. The average level of contamination was
found to be about 20 Bq/kg (134 Cs+137 Cs). However, this is likely to be the artifact caused by the
software-generated “operational background”.
1 The anthropometric characteristics of the subjects
Figs. 1,2,3 show the anthropometric characteristics of the subjects measured at CRMS, and Figs. 4-7
are the corresponding 134 Cs and 137 Cs concentrations reported by the AT1316. *1
