P-477 Lessons and Learned; The Changing Industrial Health Needs After the Nuclear Disaster and Implications for Future Disasters

Introduction The Fukushima Daiichi Nuclear Power Plant (1F) accident posed significant challenges to industrial health management. The University of Occupational and Environmental Health, Jaan played a vital role in providing support during the aftermath. Understanding the dynamic changes in industrial health needs over time is crucial for effective disaster response and preparedness. Method The 1F Network Research Meetings, held regularly, facilitated discussions among industrial physicians, experts, and cooperating companies. Through a thorough review of meeting minutes, we categorized the industrial health needs and responses in different post-disaster stages. Result During the initial recovery phase, focus on restoring operations and managing radiation led to oversight of recovery workers’ health and safety. Challenges included inadequate heatstroke prevention during extended summer work, fatigue management from continuous shifts, and insufficient health protocols. After the decision to decommission the plant, the importance of long-term health management for workers became evident, resulting in precise health examinations. The increased risk of internal exposure to alpha nuclides necessitated discussions on screening and countermeasures. Ten years later, cases of cancer with uncertain radiation origins prompted discussions on corporate responsibilities. Discussion The findings highlight the diverse Occupational health needs after nuclear disasters and underscore the need for constant preparedness for future catastrophes. The establishment of external industrial health support teams by the Japanese Ministry of Health, Labor, and Welfare is a positive step. However, maintaining readiness and mechanisms for prompt response remain crucial in navigating crises effectively. Conclusion These insights can guide policymakers and stakeholders in enhancing industrial health strategies and disaster management practices.
