The Russian–Ukrainian War of 2022 (RUW-2022) was accompanied by the subsequent risk of accidents at a nuclear power plant in Ukraine. This study investigated posttraumatic stress (PTS) symptoms related to media reports of an attack on a Ukrainian nuclear power plant during the RUW-2022 among victims of the Fukushima nuclear disaster and revealed their association with radiation risk perception (RRP) of the accident.

This cross-sectional study targeted 1193 residents of Naraha Town in Fukushima Prefecture. PTS symptoms were measured using the Japanese version of the Impact of Events Scale-Revised (IES-R). Univariate and multivariate analyses explored the association between IES-R scores and background factors, particularly RRP.

Participants with higher RRP showed significantly higher IES-R scores; furthermore, the proportion of disruption because of radiation anxiety was significantly larger among higher RRP residents. Radiation anxiety mediated the association between RRP and PTS symptoms (total IES-R score and sub-item of intrusion).

People with higher RRP in Fukushima may continue to be at risk of persistent, unwanted PTS symptoms due to future nuclear crises. Therefore, mental health practitioners need to continue providing support in affected areas for a longer period than anticipated. Moreover, a population-based approach to cope with these stressors from media reports is essential.

People with psychiatric disorders are one of the most vulnerable populations in disasters, and the 2011 Great East Japan Earthquake reported higher post-evacuation mortality rates among psychiatric inpatients. A psychiatric hospital evacuated after the nuclear accident was surveyed to gain valuable insights for future disaster preparedness.

The authors interviewed two Odaka Akasaka Hospital (a private psychiatric hospital) staff responsible for evacuation due to the nuclear accident.

At the time of the earthquake, 104 patients had been admitted to the hospital. They were instructed to evacuate on the grounds that they existed within a 20 km radius of Fukushima Daiichi Nuclear Power Station. Although the evacuation process was extraordinarily demanding, the staff acted professionally, and no patient experienced a significant deterioration in health during the evacuation.

It was reasonable to follow the evacuation order because of the difficulty of obtaining accurate information about radiation exposure and staff availability in high-risk situations. The staff’s knowledgeable and attentive care of the patients was one of the factors that enabled them to successfully carry out this severe evacuation. However, this may be related to the high mortality rate after the evacuation of patients who were separated from such caregivers.

Based on experiences following the Great East Japan Earthquake and nuclear power plant accident in 2011, Nuclear Emergency Core Hospitals (NECHs) were designated as centers for radiation disaster management in Japan. This study aimed to investigate their current status and identify areas for improvement.

This cross-sectional study was conducted in October 2018. Demographic data were collected by a questionnaire with free text responses about attitudes toward NECHs. Considerations regarding risk communications during a radiation disaster were analyzed using qualitative text mining analysis.

A total of 36 hospitals participated in this study. Only 31% of NECHs anticipated a radiation disaster. The importance of business continuity plans and risk communications was shown. Text analysis identified 7 important categories for health care workers during a radiation disaster, including media response, communications to hospital staff, risk communications, radiation effects on children, planning for a radiation disaster in the region, rumors, and the role in the region.

The radiation disaster medical system and NECHs in Japan were surveyed. The importance of risk communications, planning for a radiation disaster in each region, and the role in the region are identified as issues that need to be addressed.

The response of nurses in Japan to the Fukushima Daiichi Nuclear Power Plant accident was deemed inadequate. This study examined the issues in Japanese radiation nursing education.

Anonymous, self-administered postal questionnaires were sent to managers and teachers of 1053 basic nursing educational institutions in Japan.

Among the 342 institutions that completed the questionnaire, 218 (63.7%) had incorporated Radiological Nursing Education into their curriculum while 124 (36.3%) had not. Based on the time of their incorporation, they were divided into the pre-accident incorporation group and the post-accident incorporation groups. For 89 of 111 institutions (85.6%) in the former group, the main reason for the incorporation was radiotherapy care. For 11 of 26 institutions (42.3%) in the latter group, the incorporation was their response to the nuclear disaster.

Nursing education in Japan has been inadequate, and as such, nurses find it hard to respond to nuclear disasters. Examining the current nursing education system and building a new model based on the nuclear disaster experience are urgent issues.

The 11th of March 2011, a magnitude 9.0 earthquake struck alongside the north-east coast of Honshu Island, Japan, causing a tsunami and a major nuclear accident. The French Institute for Public Health Surveillance (InVS) set up, within one week after the triple catastrophe, an Internet-based registry for French nationals who were in Japan at the time of the disasters. In this string of disasters, in this context of uncertainties about the nuclear risks, the aim of this registry was to facilitate the: (1) realization of further epidemiologic studies, if needed; and (2) contact of people if a medical follow-up was needed. The purpose of this report was to describe how the health registry was set up, what it was used for, and to discuss further utilization and improvements to health registries after disasters.

The conception of the questionnaire to register French nationals was based on a form developed as part of the Steering Committee for the management of the post-accident phase in the event of nuclear accident or a radiological emergency situation (CODIRPA) work. The questionnaire was available online.

The main objective was achieved since it was theoretically possible to contact again the 1,089 persons who completed the form. According to the data collected on their space-time budget, to the result of internal contamination measured by the French Institute for Radiological Protection and Nuclear Safety (IRSN) and dosimetric expertise published by the World Health Organization (WHO), it was not suitable to conduct an epidemiologic follow-up of adverse effects of exposure to ionizing radiations among them. However, this registry was used to launch a qualitative study on exposure to stress and psychosocial impact of the Great East Japan Earthquake on French nationals who were in Japan in March 2011.

Setting a registry after a disaster is a very important step in managing the various consequences of a disaster. This experience showed that it is quickly feasible and does not raise adverse side effects in involved people.
