Cs 137 Application

Cesium-137 | 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 plutonium.This radionuclide has a relatively long half-life, 30 years, and decays by emitting beta particles.

Caesium-137 Wikipedia

Caesium-137 (137 55 Cs), or radiocaesium, is a radioactive isotope of caesium which 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

Application of Radioactive Fallout Cesium‐137 for

Radioactive fallout 137 Cs (cesium‐137) deposited across the landscape from atmospheric nuclear tests is strongly absorbed on soil particles limiting its movement by chemical and biological processes. Most 137 Cs movement in the environment is by physical processes; therefore, 137 Cs is a unique tracer for studying erosion and sedimentation. Cesium‐137 loss from a watershed has been shown
