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. |
