Weighted mean. listed as 110 d in ICRP (1979, (1977). This is consistent with BNL on the half-time of compartment in Marshallese 1990) and NCRP data obtained by the long-term (Miltenberger et al., 1981; Miltenberger and Lessard, 1987). because it is based on a much lar population and the difference betw 115-d_ half-life observed in 23 males is minimal. The half-time i term compartment for 21 females i study was 83 d (range 63-126 d). madea separate calculation based on A summary of BNL data presented in Figure 4 shows that the distribution of biological halflife in 23 Marshallese adult males can be considered lognormal with a median of 115 d, a mean of 119 d, and a range of 76-178 d. In our dose model for 137Cs, we used the 110-d haif-life 200 r biological half-life and the smaller for females. These two parameters to a degree, and the dose to femal somewhatless than the males.
