针对传统核辐射测量实验通常采用NIM插件式核仪器实验系统，学生只需要对不同的NIM插件进行电缆连接和简单的按键操作，不利于学生掌握最新的数字化核辐射测量技术，也不利于对学生工程实践创新能力的培养的问题，采用项目式教学理念设计了包括GM计数管脉冲计数型核辐射测量系统设计和CZT半导体探测器脉冲幅度分析系统设计等两个项目的核辐射测量综合设计实验，给出了教学活动设计建议。在完成综合设计实验的过程中，在巩固学生核辐射测量基本知识和技术的基础上可进一步锻炼初步的科学研究能力，培养学生的创新意识和思维。
In view of the problems traditional experiments of nuclear radiation measurement that using NIM modules nuclear instruments experiments system, students only need to connect different NIM modules with cables and do some easy keystroke actions, it’s not beneficial for students mastering the latest technologies of digital nuclear radiation measurement and cultivating the engineering practice innovation ability. Adopting the concept of project-based teaching, the comprehensive design experiments with two projects were designed, which were the design of pulse counting nuclear radiation measurement system for GM count tube and the design of pulse amplitude analyzing nuclear radiation measurement system for CZT semiconductor detectors. The design suggestion of teaching activities is given. In the process of completing the comprehensive design experiments, on the basis of consolidating the basic knowledge and technology of nuclear radiation measurement, the initial scientific research ability of students was exercised further, and the innovative consciousness and thinking of students could be cultivated.
