Calculations are described, based on experimental findings, which show the variation of absorbed dose from 224Ra in bone marrow of CBA/H mice. These calculations indicate that, following an injection of a leukaemogenic amount of 16 kBq 224Ra into these mice, most marrow cells in the cancellous bone of femur ends are killed but most marrow cells in the femur shaft survive. The calculations also suggest that the mean leukaemogenic absorbed dose of about 1.5 Gy is received by a population of marrow cells about 30 microns from bone surface in the femur shaft.
基于实验结果进行了计算，这些计算显示了CBA/H小鼠骨髓中224Ra吸收剂量的变化。这些计算表明，向这些小鼠注射致癌剂量的16 kBq 224Ra后，股骨末端松质骨中的大多数骨髓细胞被杀死，但股骨干中的大多数骨髓细胞存活下来。计算还表明，股骨干中距骨表面约30微米的一群骨髓细胞接受的平均致癌吸收剂量约为1.5 Gy。
