"Caesium-137 ( 55Cs ), cesium-137 (US), or radiocaesium, is a radioactive isotope of caesium that 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 spontaneous … See more Caesium-137 has a half-life of about 30.05 years. About 94.6% decays by beta emission to a metastable nuclear isomer of barium: barium-137m ( Ba, Ba-137m). The remainder directly populates the ground state of Ba, which is … See more Caesium-137 reacts with water, producing a water-soluble compound (caesium hydroxide). The biological behaviour of caesium is similar to that of potassium and rubidium.
