For the nuclide %5Fe, only one @
St.1.iment in blood was published by the BNL Medical Program (Be72); thus an est

Two conse: .tive urine or body burden data points were used to eliminate the unknown ing..tion rate from the equation.

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).
