| 摘 要： | 对载人航天器密封舱内航天员遭受的生物剂量进行研究分析，可为乘员辐射防护设计和工程实施提供依据。文章将基于一维深度-剂量计算、结合扇区射线法的三维辐射仿真技术运用于载人航天器总体设计中，以某中期驻留载人航天器为例，构建生物剂量仿真分析模型。计算实例分析表明，三维剂量仿真结果可有效指导乘员辐射防护优化设计，对后续长期载人飞行中的航天员辐射安全设计具有较强的实用性。

| Abstract: | The pressured cabin of the manned spacecraft provides the places of working and living for astronauts. It is critical to analyze the organ dose in the pressured cabin, in order to predict quantitatively the hazard on astronauts due to the space ionizing radiation. This paper discusses the technical process of the dose analysis and the method of the three-dimensional simulation of the organ dose. For a medium-term-resident manned spacecraft, the magnitude distribution of the organ doss in the pressured cabin is simulated. The simulation results can be used for the systematical design of radiation protection. |
