FIGURE 8. Absorbed fractions to TAM, (TAMTBV), for electron sources emitted uniformly within TBV at 4 values of marrow cellularity: 100%, 70%, 50%, and 25%. Data are shown for 2 skeletal sites and 2 individuals as indicated in A–D. For comparison, values are shown as well for ICRP 30 model (energy-independent dashed line) and both the Eckerman and Stabin (16) and the Bouchet et al. (17) models (energy-dependent dashed line).
