摘　　要：对于放射性、核辐射,人们几乎可以说"谈核色变"。如何在教学中利用近代物理实验中有关放射性的实验设备,使学生通过亲身实验和切身体会感受放射性对于周围环境的影响,以及各种射线同物质的相互作用,是学生在专业书面知识学习之外的另一种收获。一方面学生可以加强自身科学素养,建立良好的关于辐射安全的安全意识,另一方面使学生知道放射源并不可怕,对放射源无端的恐惧是没有必要的。本文基于商丘师范学院物理与电气信息学院的实验教学实践活动,在"用快速电子验证相对论效应"的实验中通过拓展实验加深学生对放射性的了解,理解核辐射物理本质,培养有关核物理知识的科学素养。About radiation, or nuclear radiation, it almost can be said that " Mention of Radioelement Terrible". Explorations of the use of relativity effect spectrometer in modern physics experiments in teaching could help students experiencing and being keenly aware of the influence of radiation on the environment,as well as the interaction between radiation and other matter. These are another kinds of learning besides the book knowledge. In this way,on the one hand,students can enhance their scientific literacy,establish good radiation safety consciousness,on the other hand,be aware of the radioactive source is nothing horrible. Thus,unwarrant-ed fear of radioactive source is unnecessary. This paper is written based on the teaching practice of School of Physics and Electrical Information in Shangqiu Normal University,through the expanded experiments of vindi-cating the relativistic effect by using fast electronic,we expected to deepen students' understanding of radioac-tivity,to understand the physical essence of nuclear radiation and to foster the science literacy of nuclear phys-ics.
