Understanding the behaviour of scattered radiation is important for learning appropriate radiation protection methods, but many existing visualisation systems for radiation require special devices, making it difficult to use them in education. The purpose of this study was to develop teaching material for radiation protection that can help visualise the scattered radiation with augmented reality (AR) and virtual reality (VR) on a web browser, develop a method for using it in education and examine its effectiveness. The distribution of radiation during radiography was calculated using Monte Carlo simulation, and teaching material was created. The material was used in a class for department of radiological technology students and its influence on motivation was evaluated using a questionnaire based on the evaluation model for teaching materials. In addition, text mining was used to evaluate impressions objectively. Educational material was developed that can be used in AR and VR for studying the behaviour of scattered radiation. The results of the questionnaire showed that the average value of each item was more than four on a five-point scale, indicating that the teaching material attracted the interest of users. Through text mining, it could be concluded that there was improved understanding of, and confidence in, radiation protection.
了解散射辐射的行为对于学习适当的辐射防护方法很重要，但许多现有的辐射可视化系统需要特殊设备，这使得它们在教育中难以使用。本研究的目的是开发用于辐射防护的教材，该教材可以通过网络浏览器上的增强现实（AR）和虚拟现实（VR）帮助可视化散射辐射，开发一种在教育中使用它的方法，并检验其有效性。使用蒙特卡罗模拟计算了放射摄影过程中的辐射分布，并创建了教材。该教材在放射技术专业学生的课堂上使用，并基于教材评估模型通过问卷调查评估其对学生积极性的影响。此外，还使用文本挖掘来客观地评估印象。开发了可用于AR和VR以研究散射辐射行为的教材。问卷调查结果显示，在五分制中每个项目的平均值都超过了四分，表明该教材吸引了用户的兴趣。通过文本挖掘，可以得出结论，学生对辐射防护的理解和信心有所提高。
