本文依据国内外95例空间飞行氟化锂热释光剂量计测量的舱内宇宙辐射剂量及轨道参数,建立了近地轨道载人航天器舱内剂量预先评估的数学模型。模型表明,影响舱内剂量水平的主要因素是轨道高度,呈二次曲线形式;其次是太阳活动因素。轨道倾角对舱内剂量的影响并不显著。依据模型作出了辐射安全飞行的时限曲线并就辐射的安全防护问题进行了分析讨论。
Based on the cosmic radiation doses and orbital parameters of 95 space-borne lithium fluorophilic thermoluminescence dosimeters at home and abroad, this paper establishes a mathematical model of pre-assessment of in-orbit manned spacecraft dose. The model shows that the main factor that affects the dose level in the cabin is the orbital height, which is in the form of a quadratic curve. The second is the solar activity factor. The influence of orbital inclination on the dose in the cabin is not significant. According to the model, the time-curve of radiation-safe flight was made and the radiation safety protection was analyzed and discussed.
