    Cesium in The EnvironmentCesium SourcesCesium and HealthBecause Cs-137 bonds with chlorides to make a crystalline powder, it reacts in the environment like table salt (sodium chloride): 1. Cesium moves easily through the air. 2. Cesium dissolves easily in water. 3. Cesium binds strongly to soil and concrete, but does not travel very far below the surface. 4. Plants and vegetation growing in or nearby contaminated soil may take up small amounts of Cs-137 from the soil.Small quantities of Cs-137 can be found in the environment from nuclear weapons a...

    Caesium (IUPAC spelling ) (also spelled cesium in American English) is a chemical element with the symbol Cs and atomic number 55. It is a soft, silvery-golden alkali metal with a melting point of 28.5 °C (83.3 °F), which makes it one of only five elemental metals that are liquid at or near room temperature. Caesium has physical and chemical properties similar to those of rubidium and potassium. The most reactive of all metals, it is pyrophoric and reacts with water even at −116 °C (−177 °F). It is the least electronegativeele

    IntroductionThe Dangers of Cesium-137The Legacy of Cesium-137 After Nuclear AccidentsTreatment of Cesium-137 Ingestion with Prussian BlueFinal SummaryReferencesAmong the many fission product nuclides, cesium 137 deserves attention because it possesses a unique combination of physical properties and historical notoriety. It is readily produced in large quantities during fission, has an intermediate half-life, decays by high-energy pathways, and is chemically reactive and highly soluble. These physical properties have made cesium 137 a dangerous legacy of major nuclear accidents such as Chernobyl, but it has also caused relatively small incidents as w...

  • Cesium-137 Cs - PubChem

    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 years, and decays by emitting beta particles.
