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 studies in support of this mission. Studies can be categorized by radiation type and/or exposure:


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.

Tools and Resources

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