Development of an Application for Sustainable Support of Returning Residents Displaced by the Fukushima Nuclear Accident.

We developed a mobile application (app) to help communication between support providers and residents who have returned from evacuation after the Fukushima nuclear power plant accident. Surveys were conducted among returning residents and support providers in coastal areas of Fukushima Prefecture, from which application functions and layout were decided. App functions were included to estimate external exposure, monitor health, and facilitate interactive health counseling.
