The Fukushima Medical University (FMU) International Symposium on the Fukushima Health Management Survey (FHMS) convened for the fourth time in March 2022 to share FHMS findings within Fukushima and beyond. Dr. TAKENOSHITA Seiichi, FMU President, underscored Fukushima’s restoration journey, while Governor UCHIBORI Masao committed to partnering with FMU for residents’ welfare.
The Introduction by Dr. KAMIYA Kenji highlighted FHMS results for more than 460,000 participants, of whom 99.8% were exposed to radiation doses below 5 mSv post-accident. Thyroid examinations detected tumors, but no dose-response relationship was found. The Comprehensive Health Check showed increased lifestyle-related diseases among evacuees, with improvements in some health markers. Mental health issues initially prevalent after the accident decreased over time, and perinatal outcomes were consistent with national data.
Session 1 focused on radiation effects in Fukushima. The UNSCEAR 2020 Report indicated significantly reduced radiation exposure estimates and negligible cancer risks. Studies from Hiroshima, Nagasaki, and Chernobyl found no radiation-induced genetic effects.
Session 2 explored post-disaster well-being, emphasizing the evolution of psychological responses. Practices like Psychological First Aid (PFA) and emotional resilience promotion were highlighted. Katsurao Village’s post-evacuation health measures addressed lifestyle diseases, but faced challenges. The WHO framework for mental health and psychosocial support in nuclear emergencies emphasized the importance of mental health care throughout all disaster phases.
The symposium facilitated valuable insights, underlining comprehensive health strategies and the significance of long-term studies for Fukushima’s recovery and health management.
