Caesium-137 - Wikipedia
Caesium-137 (137 55 Cs), cesium-137 (US), [7] 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 fission of uranium-238. It is ...

3 天之前 · The most common radioactive form of cesium (chemical symbol Cs) is Cesium-137. Cesium-137 is produced by nuclear fission for use in medical devices and gauges and is one of the byproducts of nuclear fission in nuclear reactors and nuclear weapons testing.
What is cesium-137? Radioactive cesium-137 is produced spontaneously when other radioactive materials such as uranium and plutonium absorb neutrons and undergo fission. Cesium-137 is therefore a common radionuclide produced when nuclear fission, or splitting, of uranium and plutonium occurs in a reactor or atomic bomb. What are the uses of ...
