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 …
Caesium-137 (137 55 Cs, Cs-137), cesium-137, 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.It is among the most problematic of the short-to-medium-lifetime …

The total atmospheric release of radioactive cesium (134+137 Cs) has been estimated to be 20 PBq (from March 12 to 31, 2011) by TEPCO (TEPCO, 2012), which is 1.4% of the total radioactive cesium inventory (∼1420 PBq) of units 1, 2, and 3 of the Fukushima Daiichi Nuclear Power Plant before the accident (Nishihara et al., 2012).
Cesium is a member of the alkali metals. It has an atomic symbol Cs, atomic number 50, and atomic weight 132.91. Cesium has many industrial applications, including the construction of atomic clocks based on its atomic vibrational frequency.
