Cesium-137: A Deadly Hazard

Cesium-137 is an especially dangerous fission product because of its high yield during fission, moderate half-life, high-energy decay pathway, and chemical reactivity. Because of these properties, cesium-137 is a major contributor to the total radiation released during nuclear accidents.

Cs-137 | Dark Wiki | Fandom

Cesium-137, specifically, is one of the two main "medium-lived" byproducts of uranium 235 and plutonium-239 fission (along with strontium-90). It can be highly dangerous because it is produced in large quantities, has a half-life of about 30.17 years, and reacts readily with water, making it easy to absorb into soft tissue.
