“ICRP2023” was held in Tokyo from November 7 to 9, 2023, with 708 participants from 59 countries. Attendees held lively discussions for the next updating of the ICRP main recommendations that is scheduled for 2030. The Radiological Nursing Society of Japan presented four topics as poster displays: 1) classification of nurses as radiation workers and radiological protection practices; 2) an introduction to NuHAT (Nuclear Disaster Health Assistance Team); 3) radiological nursing in nursing education; and 4) the establishment of dose limits for female radiation workers in Japanese radiation protection regulations. Discussions throughout the symposium focused on two issues. The first was the experiences of the professionals involved in radiological protection and the general public, including especially those experiences during the Fukushima Daiichi Nuclear Power Plant accident. The second was how to communicate with stakeholders in order to consider various social values, not limited to strict scientific evidence, when establishing the system of radiological protection in the next recommendations. The symposium suggested the strong need for radiological nursing societies and nursing professionals around the world to be actively involved in radiological protection.

The purpose of this study was to clarify the self-care that cancer patients receiving outpatient radiation therapy should practice during the treatment process. First, we created a draft 48 item self-care list that should be put into practice based on a literature review and a questionnaire survey of certified nurses. Next, the content validity of the self-care list was examined using the modified Delphi method by a total of 6 people: 3 Certified Nurse Specialists in Cancer Nursing and 3 Certified Nurses in Radiation Oncology Nursing. The examination procedure consisted of a first survey using a questionnaire, a face-to-face meeting, and a second survey using a questionnaire. As a result, 44 items were selected as representing self-care that cancer patients receiving outpatient radiation therapy should practice during the treatment process, meeting the consensus standard of I-CVI 0.78 or higher. The 44 self-care items consisted of 7 items applicable to the time of choosing treatment, 10 items covering the period from decision-making to initial irradiation, 20 items relating to the treatment period, and 7 items concerning the period after treatment. The created 44 item self-care list can be used as nursing indicators to support self-care, and help improve patients’ self-care.
