rate from the equation. This method yields n-l estimates of Kp where n was the number of data points. An average value of K.. 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, ICRP68, ICRP69, ICRP79, Ki78). A representative sample of these parameters is presented in Table 4.

The values of K.. were similar for males and females and for residents of Rongelap and Utirik. For 905, on Rongelap a factor of 2 difference between K, 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
