Since mean free paths for nuclear fragmentation are of the order of the ranges of primary Galactic Cosmic Ray (GCR) nuclei, determination of the radiation field produced by successive fragmentations of nuclei in material and tissue is essential to accurate assessment of GCR radiation risk to humans on long-duration missions outside the geomagnetosphere. We describe some recent measurements made at the Bevalac of heavy ion transport through materials, with representative results and examples of how they may be applied to aspects of the space radiation problem, including efforts to devise analytical tools for predicting biological effects and for designing spacecraft shielding.
由于核裂变的平均自由程与初级银河宇宙射线（GCR）核的射程相当，因此确定物质和组织中核连续裂变产生的辐射场，对于准确评估在地磁层外执行长期任务的人类所面临的GCR辐射风险至关重要。我们描述了最近在贝伐拉克进行的一些关于重离子在材料中传输的测量，给出了代表性结果以及它们如何应用于空间辐射问题各方面的示例，包括为预测生物效应和设计航天器屏蔽而设计分析工具的工作。
