放射性同位素是日常生活中必不可少的一部分,也是医学、催化和能源领域不断扩大的研究领域。在这里,我们将介绍一项教育活动,介绍放射性衰变的概念以及相应的好处、风险和安全处理策略。具体来说,我们开发了一个互动纸牌游戏,放射性和235u,作为一个活动,可以在完全远程设置中实施,而不需要训练有素的教练或特定的,以前获得的专业知识。纸牌游戏由72张纸牌和50个代币组成,并包含两个远程访问的介绍视频的链接,内容包括(1)放射性衰变的基本概念和(2)游戏玩法说明。这项活动的目的是让学生熟悉放射性衰变、屏蔽和放射性同位素应用的概念。游戏玩法鼓励学生通过收集和使用屏蔽卡来预防、减少或限制暴露于放射性剂量,同时也学习有关放射性同位素及其稳定同系物的事实。这款游戏的测试对象是大学生。活动前和活动后问卷调查了学生对放射性的使用和危害的熟悉程度和看法。结果表明,该活动适合介绍有关放射性核素、放射性衰变和屏蔽的基本概念。我们还观察到,在研讨会结束后,学生对核化学及其在世界上的作用的看法从中性转变为略微积极。
Radioactive isotopes are an essential part of everyday life and an expanding area of research in the fields of medicine, catalysis, and energy. Here, we describe an educational activity that introduces the concept of radioactive decay and the corresponding benefits, risks, and safe handling strategies. Specifically, we have developed an interactive card game,Radioactivity and235U, as an activity which can be implemented in a fully remote setting without the need for a trained instructor or specific, previously acquired expertise. The card game consists of 72 playing cards and 50 tokens and contains links to two remotely accessible introductory videos on (1) fundamental concepts of radioactive decay and (2) instructions on gameplay. The goal of this activity is to familiarize students with the concepts of radioactive decay, shielding, and applications of radioactive isotopes. Gameplay incentivizes students to prevent, reduce, or limit exposure to a radioactive dose by collecting and using shielding cards, while also learning facts about radioactive isotopes and their stable congeners. The game was tested with undergraduate college students. Pre- and postactivity questionnaires measured the students’ familiarity and opinion on the use and harm of radioactivity. The results indicate that the activity is suitable to introduce basic concepts surrounding radionuclides, radioactive decay, and shielding. We additionally observed a shift in students’ opinions of nuclear chemistry and its role in the world from neutral to slightly positive after the workshop.
