| 对于放射性，对于核辐射，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，是在学生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教育教学实践，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。 |

Towards Radioactivity or Nuclear radiation, It can almost be said that "turn pale at the mention of nucleus" to people. Exploring the ways to use radioactive laboratory equipment in Modern physics experiments during school teaching. Making students to experence the impacts of radioactivity on the environment and discovering the interaction among various radiations, it can be a great harvst beside student's knowledge from professional books. On the one hand, Students can strengthen their own scientific literacy and establish a good safety awareness on radiation safety. on the other hand, they can realise that radioactive sources is not terrible and unwarranted fear of radioactive sources is not necessary. Based on the Teaching Practice from the Physics and Electrical Information college of Shangqiu Normal University, the thesis was use to deepen students' understanding of radioactivity by the extending experiments of "verifing the Relativistic effects with fast electronics", and to Understand the physical nature of nuclear radiation to develop scientific literacy of nuclear physics. 自己再改下吧 |

About radiation, or nuclear radiation, it almost can be said that "the mere mention of the nuclear talks". Explorations of the use of experimental equipments on radioactivity 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,unwarranted fear of radioactive source is unnecessary. This paper is written based on the teaching practice of physical and electrical information colledge in Shangqiu Normal University, through the expanded experiments of verificating the relativistic effect by using fast electronic, we expected to deepen students' understanding of radioactivity,to understand the physical essence of nuclear radiation and to foster the science literacy of nuclear physics. |
