The 13705 dose equivalent is important over the long It may be the chief nuclide of concern during an individuals life time pest rehabitation of a fallout contaminated environment. Statistical Analysis of Data In the cases of 1376., $320 and 52, a large set of individual aduit values for k and P° were available in addition to a set of adult average values. The whole-body counting techniques and urine bioassay techniques employed were similar throughout the programs’ history. The short-term factors influencing the pattern of an individual's body burden, e.g. sickness, local diet changes, eating imported food, recent travel to uncontaminated areas, etc. were factors which influenced the pattern of adult average body burden throughout the entire residence interval. Therefore the ratio of the standard deviation to the adult average k's and P°'s should have been equal to the same ratio for individual adult values. This was in fact the case for 1374, , 6520 and 9... The standard deviations and the adult average k's and P°'s for these nuclides were listed in Table 4. Tables of individual adult values were not reproduced here, however, individual body-burden data obtained in sequence are found in the references given in the introduction. These body burdens may be used with a fitting func- tion (Eq. 2) to generate individual adult, k's and P°'s. The standard deviations for adult average k's and P°'s were used to estimate the standard deviations for adult average committed effective dose equivalents (see Table 4). Because the ratio of standard deviation to the average k and P° was the same for either adult average or individual adult k and P° data for 137, 8, 65 Zn and 90 Sr, it was assumed to be true the standard deviations for the adult average k, P°, 17 for 60 Co and 55 Fe. Thus, fifty-year cumulated intake °
