This study aimed to clarify the motivations and timing of the decision to become radiation oncologists. Materials and methods: We conducted an online survey for new members of the Japanese Society for Radiation Oncology (JASTRO). Results: The response rate was 43.3%. Data of the 79 respondents who wanted to obtain a boardcertification of JASTRO were analysed. We divided the respondents into two groups: Group A, those who entered a single radiation oncology department, and Group B, those who joined a radiology department in which the radiation oncology department and diagnostic radiology department were integrated. The most common period when respondents were most attracted to radiation oncology was "5th year of university"in Group A and "2nd year of junior residency"and "senior residency"in Group B. Furthermore, 79.5% of Group A and 40% of Group B chose periods before graduation fromauniversitywitha significant difference. Themost commonperiodwhen respondents made up their minds to become radiation oncologists was "2nd year of junior residency"in both groups. Internal medicine was the most common department to consider if they did not join the radiation oncology or radiology department. Conclusion: To increase the radiation oncologists, it is crucial to enhance clinical training in the fifth year of university for Group A and to continue an active approach tomaintain interest in radiation oncology until the end of junior residency. In Group B facilities, it is desirable to provide undergraduates more opportunities to come in contact with radiation oncology.
