Corrected f factors for photons from 10 keV to 2 MeV

Section 4 of ICRU Report No. 30 contains information on determining the absorbed dose from exposure. Table 4.1 lists the f factor for relating absorbed dose to exposure for photons from 10 keV to 2 MeV under conditions of charged particle equilibrium for water, bone, and muscle. Upon inspection, one notices that although the water values have not changed significantly, the muscle values differ by as much as 6% from previous tables in ICRU Report Nos. 17 and 24. A recomputation of the data indicates that errors exist in the published values. Corrected f factors for photons from 10 keV to 2 MeV are calculated in this communication.
