6mCs
6mCs is a designation that refers to cesium-137, a radioactive isotope of cesium. Cesium-137 is a byproduct of nuclear fission and is produced in significant quantities during the operation of nuclear reactors and in nuclear weapons testing. It has a half-life of approximately 30 years, meaning that after 30 years, half of the initial amount of cesium-137 will have decayed.
This radioactive isotope is a gamma emitter, meaning it releases high-energy photons as it decays. Due to
Major releases of cesium-137 into the environment have occurred from nuclear accidents, such as Chernobyl in
