Radionuclide Basics: Cesium-137. Cesium (chemical symbol Cs) is a soft, flexible, silvery-white metal that becomes liquid near room temperature, but easily bonds with chlorides to create a crystalline powder. The most common radioactive form of cesium is Cs-137. Cesium-137 is produced by nuclear. for use in medical devices and gauges.
