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). Lit Table A representative sample of these parameters is present: 4.
