rate from the equation. This method yields n-i estimates of Ky where n was the number of data points. An average value of Kk was assigned for each nm 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, [CK!'68, ICRP69, ICRP79, Ki78). A representative sample cf these parameters is preseuted in Table 4, Table 3 Summary of Dietary Rate Constants (Kes aot) 60, 90, 65, oe 1.8107 3.1x107* st xo Females 1.6x30> 4 ixlO™ 3,.5el07® Lx Adults 15x10"? _1,9x107 3.1xlo > L.4xl0™ Males N.D. 4.6x107 N.D.
