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.

Register Today for the 2015 Radiation Epidemiology and Dosimetry Course

REB periodically offers an in-depth course intended for people with backgrounds in epidemiology, who are interested in learning about the health effects of radiation exposure—particularly the relationship between ionizing radiation and cancer. Learn more about the May 2015 Radiation Epidemiology and Dosimetry Course, and register today.

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.

Staff Spotlights

Dr. Steven Simon is an internationally-recognized expert in radiation dose reconstruction in support of epidemiologic studies, especially in the area of occupational and environmental exposures and cancer. Read more about Dr. Simon's work.
