20ci中子源在工作状态时,中子发射率大,对源室的辐射较大,在较长时间使用中子源的过程中,不可避免对在源室的工作人员和周边环境造成不同影响,为保障中子源的安全使用,满足辐射防护的安全标准和优化要求。南华大学核科学技术学院研究了中子源对四周产生辐射剂量的分布情况,对源辐射分布进行实地检测及数据分析等研究工作。为中子源将采取最佳屏蔽措施提供一份参考依据。

Once the 20ci neutron source in the working state, the neutron emission rate is high, and the radiation to source chamber is large. A long time in the process of using the neutron source will bring about inevitable effects staffs in the source chamber and the sur- rounding environment. For the protection of the safe use of neutron sources, to meet safety standards and radiation protection optimization requirements, this paper discussed the effect of a research sources on the surrounding distribution of radiation dose, radiation source distribution Of our field testing and data analysis research. Neutron source for the best screening measures will be taken to provide a reference.
