摘要
从辐射安全和管理的角度考虑,针对目前核技术实验教学中采用活度较低的豁免源,重新设计了传统核技术实验教学中部分依赖于较强放射源的实验内容,采用基于多道分析器的能谱测量取代了基于定标器的计数测量的实验方案,利用豁免源得到了很好的实验结果,同时使学员对γ射线与物质的相互作用有了更加清楚的认知,表明了该实验方案的可行性。
From the viewpoint of radiation safety and management,the exemption source with lower activity is mostly used for the experimental teaching of the nuclear technology in many colleges and universities.In view of this situation,the experimental content for the teaching of the traditional nuclear technology which is partly dependent on the strong radioactive source is redesigned.The energy spectrum measurement based on the multichannel analyzer is used to replace the counting and measuring experimental scheme based on the scaler,and good experimental results are obtained by using the exemption source.At the same time,the students can get a clearer understanding of the interaction betweenγ-ray and substance,which shows the feasibility of the experimental scheme.
