d.-‘ury ilems during the residence interval.
For the nuclide 35Fe, only one m
Staement in blood was published by the BNL Medical Program (Be72); thus an est
wate Of K, was not possible.
Ky was determined by using equation 1 or 2 and the population subgroup
nmeai, body burdens or urine activity concentrations.
A portion of these bioass.
dut. are illustrated for adult males and females in Figures 2, 3, 4, 5 and 6.
Two conse: .tive urine or body burden data points were used to eliminate the unknown ing.. tion rate from the equation.
where n wu. the number of data points.
This method yields n-1 estimates of K
An average value of K, was assigned fo
each nuclide and the results for the Rongelap and Utirik populations are given
in Table 3.
For the evaluation of K,
E
from equations | and 2, radiological and
physiological parameters were obtained from the open literature (ICRP59,
ICRP69, ICRP79, Ki78).
