In order to assess the radiation hazard of the fission product Cs/sup 137/, it is necessary to determine its long-term turnover rate in man. Results are reported from a longterm study of Cs/sup 137/ made on five patients. Measurements of whole-body retention were made with the Brookhaven whole-body counter. It has been found that the technique of radiochemical analysis of excreta is of limited sensitivity for determining whole-body retention at very long periods of time after isotope administration. In order to assay the radiation hazard, it is further necessary to estimate the retention over the normal life span of man on the basis of the data obtained. Thus a mathematical model must be developed from which long-term extrapolations can be made. Data analysis was carried out with the use of a computer in order to determine the parameters of the mathematical functions that best describe these data. (auth)
