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 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

Ruth A. Kleinerman, an epidemiologist in the Radiation Epidemiology Branch, is the lead author of a recently published study, which identified for the first time that the type of RB1 mutation influences the risk of second cancers in retinoblastoma patients. Read more on Ruth Kleinerman.

Radiation Epidemiology and Dosimetry Course

REB periodically offers a four-day 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. Videocasts and handouts from the latest radiation epidemiology course are available online.
