In order to propose effective and efficient radiation protection and safety education in hospitals, an interview survey was conducted to identify factors that promote effective and efficient radiation protection and safety education, and a qualitative inductive analysis was performed. As a result, two core categories of factors factors promoting effective and efficient radiation protection and safety education in hospitals were derived: “Efficient management of education” and “Measures for effective education”. “Effective management of education” consists of four categories: ‘existence of an organizational culture to promote education’, ‘organization of departments and personnel in charge of education’, ‘rational practice of education’, and ‘efficient and thorough management of students’, and it was designed to achieve efficiency while maintaining a balance with reality. The “Measures for Effective Education” section consists of the following six categories: “Devices for Educational System”, “Setting Educational Goals for Each Student”, “Measures for Educational Content and Methods”, “Measures for Teaching Materials”, “Measures for Educational Evaluation”, and “Review based on Feedback”.
