Ke was determined by using equation 1 or 2 and the population subgroup nm ui. body burdens or urine activity concentrations. dul. are A portion of these bioass. 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 wa. the number of data points. This method yields n-l estimates of K An average value of Ke was assigned fo each nuclide and the results for the Rongelap and Utirik populations are given in Table 3. For the evaluation of+K, from equations | and 2, radiological and physiological parameters were obtained from the open literature (ICRP59, ICRP69, ICRP79, Ki78).
