Providing expertise to answer questions regarding the medical management of radiation incidents worldwide

As part of its primary mission for the U.S. Department of Energy (DOE), the Radiation Emergency Assistance Center/Training Site (REAC/TS) consults with federal, state and local government agencies; industries; international governments or organizations and others needing assistance with the medical management of radiological/nuclear emergencies.

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 the Oak Ridge Institute for Science and Education (ORISE) can provide dose and event reconstruction, which are critical steps in understanding radiation exposure and determining appropriate treatments.

Radiation medication countermeasures

REAC/TS professionals maintain a registry of clinical information and provide expertise to practitioners worldwide on the use of calcium-diethylenetriaminepentaacetic acid (DTPA) and zinc-diethylenetriaminepentaacetic acid (DTPA) and Radiogardase Prussian Blue (Radiogardase™).

Calcium-DTPA and zinc-DTPA are injectable chelating agents used to enhance the excretion of plutonium and other transuranics from the body. Radiogardase Prussian Blue (Radiogardase™) binds to radiocesium and thallium and enhances their excretion from the body.

Articles, manuals and guides for radiation emergency medicine

REAC/TS also maintains a collection of radiation emergency medicine resources that support the medical response and treatment of victims. Resources include technical reports, pharmaceutical package inserts and videos.
