the number of data points. An average value of Ke was assigned for each nu- clide, and the results for the Rongelap and Utirik populations are given in Table 3. For the evaluation of K, from Eq. 1 and 2, radiological and E physiological parameters were obtained from the open literature (ICRP59, ICRP68, ICRP69, ICRP79, Ki78). A representative sample of these parameters is presented in Table 4. Table 3 Summary of Dietary Rate Constants (x., a) 6004 90, 65,, 137...

The values of K, were similar formales and females and for residents of Rongelap and Utirik. For 705, on Rongelap a factor of 2 difference between Ke values was observed for males and females. The female parameter for Rongelap Atoll compares with that obtained from the Utirik data. A paired t-test of the Rongelap male and female data indicates that the male/female difference was highly probable and therefore not significant. 15 This difference leads to a
