What are the properties of cesium 137?
Cesium-137 Facts It is a soft, malleable metal with a silvery-white color. Half-life of Cesium-137 is 30.17 years. Its molecular weight is 136.9071. Its nominal mass is 137 Da, its average mass 136.9071 Da, and its monoisotopic mass 136.9071 Da.
What is the history of cesium-137?
Caesium-137 is produced from the nuclear fission of plutonium and uranium, and decays into barium-137. Before the construction of the first artificial nuclear reactor in late 1942 (the Chicago Pile-1), caesium-137 had not occurred on Earth in significant amounts for about 1.7 billion years.
What is the decay equation of cesium-137?
Cs –> 137m56Ba + e- + νe. As the Cs-137 nuclei decay to the Ba-137m nuclei, the Ba-137m atoms remain adsorbed on the surface of the resin.
