| 摘 要： | 采用MCNP对γ放射性点源的天空反散射影响进行了模拟计算,针对天空反散射的主要制约因素进行了分析,其分析结论为核电厂相应的辐射防护设计提供了参考依据。定量模拟计算了核电厂γ放射性废物包吊装期间的天空反散射剂量率水平,提出了一种基于放射性点源结果进行放射性体源天空反散射剂量率的快速评估方法,该方法的实施满足了工程实践的快速响应要求。

| Abstract: | The γ-ray skyshine due to radioactive point source was simulated with MCNP in this paper. Moreover, the main factors which affect γ-ray skyshine were studied, and the conclusions provide references for corresponding radiation protection of nuclear power plant. The γ-ray skyshine dose rate due to radioactive waste lifting at nuclear power plant was evaluated specifically, and a rapid evaluation method of γ-ray skyshine dose rate due to radioactive body-source was founded by use of the results of radioactive point-source. The implementation of this method meets the engineering rapid response requirement effectively. |
