Radiation Epidemiology Branch

Understanding the link between radiation exposure and cancer

The research mission of the Radiation Epidemiology Branch (REB) is to identify, understand, and quantify the risk of cancer in populations exposed to medical, occupational, or environmental radiation, and to advance understanding of radiation carcinogenesis.

Research Areas

REB investigators carry out a wide range of epidemiological, genetic, and radiation dosimetry research to quantify risk, identify susceptible populations, and carry out advanced exposure assessments. Learn more about REB research areas.


REB fellows enjoy unique opportunities to plan, conduct, and publish results of a variety of research studies, while receiving training in radiation epidemiology, biostatistics, molecular epidemiology, radiation biology, and cancer risk assessment from radiation exposure.

International Society for Radiation Epidemiology and Dosimetry

Join a worldwide group of radiation researchers for the inaugural meeting of the International Society for Radiation Epidemiology and Dosimetry (ISORED), May 5-8 2020, in Sitges, Spain. More information on ISORED.

Tools and Resources

REB investigators offer a variety of radiation tools and resources developed to support research into radiation and cancer risk.

REB Highlights

The Chernobyl Accident 30 Years Later

DCEG investigators are using cutting edge molecular and genetic epidemiologic methods to expand our knowledge on the relationship between ionizing radiation and cancer.
