Advising health and emergency professionals on the medical aspects of human exposure to radiation

The Radiation Emergency Assistance Center/Training Site (REAC/TS), based at the Oak Ridge Institute for Science and Education (ORISE), is always on call to provide expertise to physicians worldwide regarding the medical aspects of a radiological or nuclear incident.

As a U.S. Department of Energy (DOE)/National Nuclear Security Administration (NNSA) deployable asset, REAC/TS provides emergency response services in a radiological/nuclear event. Specialized response teams consist of physicians, nurses, paramedics and health physicists, with the team composition based on the needs of the response.

REAC/TS teams provide consultation and expertise regarding rapid dose assessment, radiological and medical triage, efficient diagnosis and medical management of radiological/nuclear incidents. REAC/TS response teams deploy with advanced life support medical equipment and maintain training in advanced medical and trauma life support.

REAC/TS professionals engage in national level exercises, table top exercises and exercise events for other agencies and facilities that involve radiological/nuclear materials, providing expertise on the medical management of the victims. In the event of an actual radiological/nuclear incident, health physicists from REAC/TS and ORISE can provide dose and event reconstruction, which are critical steps in understanding radiation exposure and determining appropriate treatments.

A cytogenetic biodosimetry laboratory, which can be used to determine the radiation dose to a victim, is also located at ORISE in Oak Ridge, Tenn.
