The paper describes an original methodology for evaluation of the radiation hazard to cosmonauts on mission based on generalized dose from ionizing radiations. This is a new dosimetric functional that allows convert the complex radiation of space to standard radiation. The conversion is achieved by calculation of mean tissue equivalent doses from each source of radiation hazard in space flight and scaling factors which take into account the radiobiological effect of intricate macrospatial and temporal dose distributions along the human body. Besides, consideration is given for the impact of non-radiation factors inherent to space flight. The generalized dose which is the dose from standard radiation inducing radiation damage similar to the multicomponent space radiation can be used to ascertain the character and degree of performance degradation, and radiation risk for cosmonauts both in and long after mission.
本文描述了一种基于电离辐射的广义剂量来评估航天员执行任务时辐射危害的原创方法。这是一种新的剂量学函数，可将复杂的空间辐射转换为标准辐射。通过计算太空飞行中每个辐射危害源的平均组织等效剂量以及考虑人体复杂宏观空间和时间剂量分布的放射生物学效应的比例因子来实现这种转换。此外，还考虑了太空飞行固有的非辐射因素的影响。广义剂量，即来自标准辐射的剂量，其诱导的辐射损伤与多组分空间辐射相似，可用于确定任务期间及任务结束后很长一段时间内航天员的性能下降特征和程度以及辐射风险。
