What happens to Cs-137 when it gets into the environment?
Cs-137 is produced by nuclear fission for use in medical devices and gauges. Cs- 137 is also one of the byproducts of nuclear fission • processes in nuclear reactors and nuclear weapons testing. The half-life (length of time it takes for one-half of atoms to decay) of Cs-137 is 30 years. How is Cs-137 used? Cesium-137 is used in small amounts for

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 ...
