Caesium-137 - Wikipedia

Caesium-137 (137 55 Cs), or radiocaesium, is a radioactive isotope of caesium that is formed as one of the more common fission products by the nuclear fission of uranium-235 and other fissionable isotopes in nuclear reactors and nuclear weapons.Trace quantities also originate from natural fission of uranium-238.It is among the most problematic of the short-to-medium-lifetime fission products.

Cesium, Radioactive - Other Properties

The radioactive isotopes have a wide range of half-lives ranging from about 0.57 seconds (cesium-114) to about 3X10+6 years (cesium-135). The radioactive isotopes cesium-137 and cesium-134 are significant fission products because of their high fission yield, their long half-lives, and their biochemical similarity to potassium.
