Four Japanese subjects (three males and a female) were measured for their whole body retention and excretion rate following oral administration of <SUP>132</SUP>Cs. For the retention and distribution studies, awhole body counter-scanner that was built at this institute was used. In this first report, short and long-term biological half-lives, daily urinary and fecal excretion rates and the calibration constants for <SUP>137</SUP>Cs in the body are reported. Although the excretion patterns obtained were quite similar to those already reported by others, the mean long-term biological halflife for the three male subjects, (73 days ranging from 65.5 to 82.0 days) was rather smaller than other values. The short-term half-life is caused by a large excretion rate in urine in a few days following the administration.
