Abstract

The article presents a new procedure of calculating the shielding functions for irregular objects formed from a set of nonintersecting (adjacent) triangles covering completely the surface of each object. Calculated and experimentally derived distributions of space ionizing radiation doses in the spherical tissue-equivalent phantom (experiment MATRYOSHKA-R) inside the International space station were in good agreement in the mass of phantom depths with allowance for measurement error (-10%). The procedure can be applied in modeling radiation loads on cosmonauts, calculating effectiveness of secondary protection in spacecraft, and design review of radiation protection for future space exploration missions.

摘要

本文提出了一种新的计算屏蔽函数的方法，该方法适用于由一组完全覆盖每个物体表面的不相交（相邻）三角形构成的不规则物体。考虑到测量误差（-10%），国际空间站内球形组织等效体模（MATRYOSHKA-R实验）中空间电离辐射剂量的计算分布与实验得出的分布在体模深度范围内吻合良好。该方法可应用于模拟宇航员所受辐射负荷、计算航天器二次防护的有效性以及对未来太空探索任务的辐射防护进行设计审查。
