摘　　要：基于创新型人才培养视角,对放射源定位方法研究引入实验教学进行探讨。将科学研究的优势资源引入实验教学,开发伽马放射源定位和伽马辐射场监测这两个实验项目。实验中利用4个NaI闪烁体探测器同时测量137Cs放射源得到的计数率,通过EM算法迭代计算,采用极大似然估计的定位方法确定几个点状放射源的空间位置、活度及数量。通过教学实践和学生反馈对实验项目进行了修改完善,实现了科学研究与实验教学的有机结合。The study explores the introduction of radioactive source location method research into experimental teaching based on the perspective of innovative talent training,introduces the superior resources of scientific research into experimental teaching,and develops two experiment projects,i.e.gamma radioactive source location and gamma radiation field supervision.4 NaI scintillator detectors are used to measure 137Cs radioactive sources at the same time to get the counting rate.The EM algorithm is used to calculate iteratively,and the maximum likelihood estimation is used to determine the location,activity and quantity of several point radioactive sources.Through the teaching practice and student’s feedback,the experimental projects have been modified and improved,and the organic combination of scientific research and experimental teaching has been realized.
