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.

This difference leads to a
