Medical and health surveillance in postaccident recovery: experience after Fukushima

The accident at Fukushima Daiichi nuclear power plant occurred following the huge tsunami and earthquake of 11 March 2011. After the accident, there was considerable uncertainty and concern about the health effects of radiation. In this difficult situation, emergency responses, including large-scale evacuation, were implemented. The Fukushima Health Management Survey (FHMS) was initiated 3 months after the accident. The primary purposes of FHMS were to monitor the long-term health of residents, promote their well-being, and monitor any health effects related to long-term, low-dose radiation exposure. Despite the severity of the Fukushima accident and the huge impact of the natural disaster, radiation exposure of the public was very low. However, there were other serious health problems, including deaths during evacuation, increased mortality among displaced elderly people, mental health and lifestyle-related health problems, and social issues after the accident. The Nuclear Emergency Situations - Improvement of Medical and Health Surveillance (SHAMISEN) project, funded by the Open Project For European Radiation Research Area, aimed to develop recommendations for medical and health surveillance of populations affected by previous and future radiation accidents. This paper briefly introduces the points that have been learned from the Fukushima accident from the perspective of SHAMISEN recommendations.
