FACT SHEET: EPA FACTS ABOUT CESIUM-137
Cesium-137 is significant because of its prevalence, relatively long half life (30 years), and its potential effects on human health. Cesium-137 emits beta particles as it decays to the barium isotope, Ba-137m (half life = 2.6 minutes). How are people exposed to cesium-137? People may be exposed externally to gamma radiation emitted by cesium ...

Fact Sheet 0902
Cesium (Cs) is a soft, flexible, silvery-white metal that becomes liquid near room temperature, but easily bonds with chlorides to create a crystalline powder. The most common radioactive form of cesium is Cesium-137 (Cs-137). Cs-137 is produced by nuclear fission for use in medical devices and gauges. Cs- 137 is also one of the …

Radiogardase
Cesium-137 (137Cs) has a physical half-life of 30 years with a beta energy peak at 174.0 keV. Following entry into the blood, it is distributed uniformly through all body tissues. Approximately 10% of cesium is eliminated rapidly with a biological half-life of 2 days and 90% is eliminated more slowly, with a biological half-life of 110 days.
