Comparison of Nuclear Decay Data Derived from Recent Nuclear Structure Data Files with those of ICRP Publication 38

Abstract

Results are presented for a comparison of nuclear decay data for internal dosimetry derived from the recent Evaluated Nuclear Structure Data File (ENSDF) with those given in ICRP Publication 38. In most nuclides, values of half-life, branching fraction and total energy of radiations calculated from the ENSDF were in good agreement with those of Publication 38. However, significant differences in these values were found for several nuclides, notably 60 Fe, 79 Se, 80 Sr, 108 Ag m , 126 Ba, 202 Pb, and 231 Th. The causes of the differences were examined, and the influence of the revision of the nuclear decay data on the values of dose coefficients was evaluated for the selected nuclides.
