What is DTPA?

DTPA injectable chelating agents used to enhance the excretion of plutonium and other transuranics from the body. DTPA comes in two forms—calcium (Ca-DTPA) and zinc (Zn-DTPA)—both of which bind to radioactive plutonium, americium, and curium. Watch the video to learn more about DTPA and its use in radiation exposure treatment.

What is Prussian Blue?

Prussian Blue is an ingestable capsule that helps remove radioactive cesium and thallium from the body. One of Prussian Blue's advantages is that it reduces amount of time the body is exposed to radiation. Watch the video to learn more about Prussian Blue (Radiogardase) and its use in the treatment of acute radiation exposure.
