Extensive database contains more than five million records for monitored individuals
As part of its mission of safety, the U.S. Nuclear Regulatory Commission (NRC) operates the Radiation Exposure Information and Reporting System (REIRS), a database containing all occupational radiation exposure records that have been submitted to the NRC under 10 CFR Part 20. Supporting the NRC in this critical role is the Oak Ridge Institute for Science and Education (ORISE), which has managed this extensive database since 2004. More than 150,000 radiation exposure records are collected and processed annually. ORISE provides the Commission with an annual report on occupational exposure, manages the NRC’s radiation exposure website, develops and maintains applications to assist licensees in accurate recording and reporting, provides data in response to ad hoc requests, and supports the use of the data in NRC-sponsored epidemiologic studies.
Additionally, the NRC and the U.S. Department of Energy (DOE) have an interagency agreement to share information and computer systems for this project. Since 1995, ORISE also has maintained a similar database for DOE—the Radiation Exposure Monitoring System (REMS).
The REIRS database dates back to 1969 when Atomic Energy Commission (AEC) licensees were required to report radiation exposure data for individual workers at the end of employment and exposure summaries for sites on an annual basis. In 1994, the NRC began requiring annual radiation exposure records for every monitored worker. Today, this extensive database encompasses 1,800-plus NRC licensees and contains more than five million records representing more than one million monitored individuals.
