Cesium CS137 | Cs PubChem

Cesium Cs 137 is a radioactive isotope of cesium with an atomic mass of 139 and potential application in radiotherapy. Cesium Cs 137 is prevalent due to its spontaneous production, which occurs as a result of nuclear fission of other radioactive materials, such as uranium and radionuclide has a relatively long halflife, 30 years, and decays by emitting beta particles.

Caesium Wikipedia

Caesium137 has been used in hydrologic studies analogous to those with tritium. As a daughter product of fission bomb testing from the 1950s through the mid1980s, caesium137 was released into the atmosphere, where it was absorbed readily into solution. Known yeartoyear variation within that period allows correlation with soil and sediment ...
