Summary

Health risks of radiation exposure in the moderate-to-high dose range have been well established. However, the risk remains unclear at low-dose ranges with protracted low-dose rate exposure, which is typical of occupational exposure. The purpose of this study is to construct a cohort of Korean radiation workers and to assess health effects associated with occupational radiation exposure. The study population is expected to be about 190,000 Korean radiation workers who have been registered with the Nuclear Safety and Security Commission since 1984. The national dose registry, the national cancer registry, the national vital statistics registry, and the national health insurance data are collected based on the Nuclear Safety Act. Through the linkage of those collected data, we will evaluate radiation-induced health risks including cancer and non-cancer diseases.
