当研究所が行ってきた福島第一原発事故の心理的影響に関する論文が,2026年8月19日に公開されました。論文のタイトルは「Long-Term Psychological Impact of the Fukushima Nuclear Accident: A Comparison of Returnees, Continued Evacuees, and Relocators 12-13 Years Post-Disaster」です。International Journal of Disaster Risk Reduction誌に掲載されました。
同論文では,原発事故により全町避難を経験した福島県浪江町の住民を対象に,事故から12〜13年が経過した2023年から2024年にかけて質問紙調査を実施し,避難指示解除後の居住のあり方(帰還・避難継続・移住)と心の健康との関連を分析しました。あわせて,低線量放射線汚染地域である福島県内の住民,および原発事故の影響を受けていない他県の住民を比較対象とし,心理的症状(心的外傷後ストレス反応,抑うつ反応),放射線不安,精神的健康度(WHO-5),主観的幸福感などを検討しています。
分析の結果,浪江町の住民は他の2群に比べて心理的症状が高く,精神的健康度や幸福感が低い状態にあり,事故から12年以上が経過してもなお心理的影響が残っていることが示されました。また浪江町の住民の中では,帰還した人は避難を継続している人よりも失望感が高く,移住した人の精神的健康度や生活満足感が相対的に高いという結果が得られました。

Our research institute's paper on the psychological impact of the Fukushima Daiichi nuclear power plant accident was published in August 2026. The title of the paper is "Long-Term Psychological Impact of the Fukushima Nuclear Accident: A Comparison of Returnees, Continued Evacuees, and Relocators 12-13 Years Post-Disaster", and it was published in the International Journal of Disaster Risk Reduction.
In this study, a questionnaire survey was conducted in 2023-2024, 12-13 years after the accident, with residents of Namie Town, Fukushima, a town whose entire population was once forced to evacuate. The study examined how residential choices made after the evacuation orders were lifted -- returning home, continuing to evacuate, or relocating -- are related to mental health. Residents of low-dose contaminated areas in Fukushima and residents of unaffected prefectures were surveyed as comparison groups, and psychological symptoms (post-traumatic stress responses and depressive responses), radiation anxiety, psychological well-being (WHO-5), and subjective happiness were assessed.
The results showed that Namie residents reported more psychological symptoms and lower psychological well-being and happiness than both comparison groups, indicating that the psychological impact of the accident remains observable more than 12 years later. Among Namie residents, returnees reported greater disappointment than those who continued to evacuate, while those who relocated scored relatively higher on psychological well-being and life satisfaction.
