Caesium137

Caesium137

Caesium137 (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 uranium235 and other fissionable isotopes in nuclear reactors and nuclear quantities also originate from natural fission of is among the most problematic of the shorttomediumlifetime fission products.
