Diagnosis and treatment involving radiation are advanced and specialized, and the application range of radiation use is expanding year by year. Under these circumstances, nurses are engaged in caring for patients undergoing radiation for diagnosis and treatment in various clinical settings. Meanwhile, in response to the Fukushima Daiichi Nuclear Power Plant accident, the importance of radiation education for basic nursing and continuing education was recognized. Therefore, Hirosaki University Graduate School of Health Sciences has been holding “radiological nursing seminars” aimed at improving nurses’ knowledge of and practical ability in radiation. In addition to reporting on this activity, we examined the interests and needs related to radiological nursing based on the results of questionnaire surveys conducted on the participants of the seminars. The results of the surveys suggest that nurses have a high degree of interest in radiation and motivation for learning and that radiological nursing seminars are effective for helping nurses obtain a better understanding of radiological nursing.
