Radiation Epidemiological Study

Radiation workers and dose registry in Japan

In Japan, the operation and maintenance of nuclear power plants is carried out not only by employees of electric power companies but also by employees of
many nuclear energy-related companies including subcontractors. In order to centrally manage the dose records of workers who might move from company to
company, the Radiation Dose Registry Center was established by the Radiation Effects Association (REA) in 1977.

Mission of the REA

The REA has two missions related to the radiation exposure of nuclear workers; one is managing the above-mentioned dose registry, and the other is performing the radiation epidemiology study.

Radiation epidemiological study

The REA has studied a cohort of radiation workers since 1990 and have compiled a study report in Japanese every five years.
