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

For 905, on Rongelap a factor of 2 difference between Kp 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
