For more than 50 years, radioactive 137Cs has been a major source material for radioactive sealed sources, usually constructed as cesium chloride (CsCl) salt loaded into double-walled, stainless-steel capsules. A complication develops as 137Cs decays to 137Ba since this process creates a strongly reducing environment inside the capsule.
