Electron-specific absorbed fractions were calculated for selected organs and regions of the mathematical reference man. The organs or regions considered were those with high surface-to-volume ratio, organs with walls, and organs that have subdivisions. The calculated specific absorbed fractions for electrons are a complement to be used with the Medical Internal Radiation Dose (MIRD) methodology. New estimates of S-values for 80 radionuclides were calculated using the new electron-specific absorbed fractions for 21 combinations of source-target regions and were compared with those already published in MIRD Pamphlet No. 5 Revised. Small differences in S-values were found by using electron specific absorbed fractions when the source organ is the target organ. However, large differences in S-values were found for those organs with walls. 5 refs., 5 figs., 2 tabs.
