Outline of Research at the Start

東京電力福島第一原子力発電所事故から11年後の現在、福島県双葉郡双葉町ではようやく準備宿泊が開始されたが、双葉町住民の35%以上が県外に避難を継続しており、帰還意志を有する住民は全住民のわずか1割に留まっている。避難者の帰還企図は避難所住民の生活の質、放射線リスク認識、避難先の位置、受けた地域社会の支援内容等に大きな影響を受けることが明らかになっている。本研究は、双葉町住民を対象にアンケート調査を実施することにより、避難先の違いが、帰還企図、放射線リスク認識、およびメンタルヘルスやQOLの指標に与える影響を明らかにし、復興に向けた最適なリスクコミュニケーションのあり方を探索する。

Outline of Final Research Achievements

Twelve years after the Fukushima nuclear accident, anxiety about nuclear radiation persists among evacuees in Futaba town. As the only town with government functions relocated outside Fukushima Prefecture, more residents have evacuated outside the prefecture. Although various factors affect risk perception, the impact of evacuation destination remains unknown. In 2022, a survey was conducted among 404 evacuees aged > 18 years, revealing significant relationships between evacuation destination and risk perception of genetic effects in the next generation (OR = 1.92, 95%CI: 1.15-3.20) and health effects of radiation (OR = 1.76, 95%CI: 1.10-2.84), which were higher among those who had evacuated outside Fukushima. These findings emphasize the importance of evacuation destination choice and information access for evacuees' risk perception. Enhanced education efforts are necessary to help evacuees not only in Fukushima but also throughout Japan.

Academic Significance and Societal Importance of the Research Achievements

この結果から、放射線被ばくによる健康、遺伝的リスク、トリチウム水の安全性に対する懸念は、福島県内外の避難者の間で持続しており、災害後の回復における継続的な課題を反映している。福島県外に居住する一部の避難者は放射線リスクに対する懸念が高く、放射線に関する教育の必要性が福島県内に留まらず、県外や日本全国に及ぶことを示唆している。これらの知見は、災害後の回復プロセスにおける課題と対策の検討に寄与する。
