When shielding from cosmic heavy ions, one is faced with limited knowledge about the physical properties and biological responses of these radiations. Herein, the current status of space shielding technology and its impact on radiation health is discussed in terms of conventional protection practice and a test biological response model. The impact of biological response on optimum materials selection for cosmic ray shielding is presented in terms of the transmission characteristics of the shield material. Although liquid hydrogen is an optimum shield material, evaluation of the effectiveness of polymeric structural materials must await improvement in our knowledge of both the biological response and the nuclear processes.
在屏蔽宇宙重离子时，人们对这些辐射的物理特性和生物反应的了解有限。本文根据传统的防护实践和一个测试生物反应模型，讨论了空间屏蔽技术的现状及其对辐射健康的影响。根据屏蔽材料的传输特性，阐述了生物反应对宇宙射线屏蔽最佳材料选择的影响。尽管液态氢是一种最佳的屏蔽材料，但对聚合物结构材料有效性的评估必须等待我们对生物反应和核过程的了解有所改进。
