A new nursing curriculum will be introduced from 2019, and it will include modules on radiation. Since 2005, Nagasaki University has launched lectures on radiological nursing for senior nursing students to better understand the impact of radiation in the atomic-bombed areas. Therefore, in this study, we reported on radiation component of nursing curriculum at Nagasaki University and obtained suggestions regarding the content after introducing the new curriculum. When launched in 2005, radiation lectures were allocated 15 hours within the program. However, we revised the lecture time to 30 hours after the accident at Fukushima Daiichi Nuclear Power Station. The lecturers were various medical personnel such as medical doctors, registered nurses, public health nurses, dentists, and so on. The contents of this curriculum were basic radiation medical sciences, radiation health effects, nursing for the patients receiving radiation therapy, and nursing after nuclear accidents. Student responses on the original questionnaire before and after the lectures indicated increased total and content score. Through the 30 hours of lectures, students gained the knowledge of radiation. Nevertheless, we experienced several difficulties in setting the lecture time due to an overcrowded nursing curriculum and the lack of faculty experts on radiation. In the future, it will be necessary to organize classes at each university. For this reason, we hope this report will beneficial as a reference.
