Treatment of internal contamination with radioactive cesium and thallium, including Cs-137 contamination from nuclear accidents or incidents.
Binds cesium and thallium ions through ion-exchange, adsorption, and mechanical trapping within its crystal lattice structure. Once bound, the radioactive elements are trapped and excreted through the digestive system.
Should be administered as soon as possible after exposure for maximum effectiveness. Requires adequate hydration to help eliminate bound toxins. May cause constipation or other gastrointestinal effects. Treatment duration depends on contamination levels and individual patient factors.
