For the femoral head and humeral epiphysis, a reference cellularity factor of 0.25 (25% active marrow and using the macrostructural transport model for self-irradiation of the active marrow within the femoral head and 100% marrow cellularity using macrostructural transport model for femoral head At high energies, the active and inactive marrow components experience the same absorbed dose independent of their respective volume fractions within the	./cache/work_wt3ujyp45bfnlke3cmvm2337g4.pdf	./txt/work_wt3ujyp45bfnlke3cmvm2337g4.txt
