rate from the equation.
This method yields n-l estimates of Ky where n was
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
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 90... 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.

This difference leads to a
