Using the Langley Research Center galactic cosmic-ray transport computer code and the Computerized Anatomical Man model, initial estimates of interplanetary exposure of astronauts to galactic cosmic rays, during periods of solar minimum activity, are made for a realistic human geometry shielded by various thickness of spacecraft aluminum shielding. Conventional dose assessment in terms of total absorbed dose and dose equivalent is made for the skin, ocular lens, and bone marrow. Included in the analyses are separate evaluations of the contributions from the incident primary ions, from subsequent-generation fragmentation products, and from target fragments. In all cases considered, the equivalent sphere approximation yielded conservative overestimates for the actual organ exposures.
利用兰利研究中心的银河宇宙射线传输计算机代码和计算机化人体解剖模型，针对处于太阳活动极小期的宇航员，在考虑不同厚度航天器铝屏蔽对真实人体几何形状进行屏蔽的情况下，对其在行星际空间中受到银河宇宙射线的照射进行了初步估算。对皮肤、晶状体和骨髓进行了基于总吸收剂量和剂量当量的传统剂量评估。分析内容包括分别评估入射初级离子、后续生成的碎片产物以及靶碎片的贡献。在所有考虑的情况下，等效球体近似法对实际器官照射量产生了保守的高估。
