What is the Fukushima Health Management Survey (FHMS)?

Following the release of radioactive materials and evacuation of residents after the nuclear accident, the FHMS was launched to estimate external exposure doses of the people in Fukushima Prefecture and to ascertain their health status, is essential for prevention, early detection and treatment of disease. The goal is to protect and promote the long-term health of Fukushima residents.

Implementation framework of the FHMS

Fukushima Prefecture is the responsible body to implement the FHMS, and Fukushima Medical University is commissioned to conduct actual surveys as advised by the Fukushima Prefectural Oversight Committee for the FHMS, which is composed of experts.
The Radiation Medical Science Center for the FHMS was established as the implementing organization.

Design and scheme of the FHMS

Components of the FHMS

The FHMS consists of a Basic Survey and four Detailed Surveys: Thyroid Ultrasound Examination (TUE), Comprehensive Health Check (CHC), Mental Health and Lifestyle Survey, and Pregnancy and Birth Survey.

Basic Survey

To estimate external doses during the period immediately after the nuclear accident when ambient doses were the highest.
