radionuclide splits into smaller parts. cesium-137 is a common radionuclide produced when nuclear fission of uranium and plutonium occurs in a reactor or atomic bomb. what are the uses of cesium-137 cesium-137 and its decay product, barium-137m, are used in food sterilization, including wheat, spices, flour, and potatoes. cesium-137 is,5 cesium137 and strontium90 capsules improving,cs-135, which is present along with the cs-137, has a half-life of about 2 million years, and it will become the dominant source of radioactivity in the cesium capsules in about 600 years. cesium and strontium have limited mobility in the environment due to adsorption on clays and other aluminosilicates.
