Radionuclide Basics: Cesium-137 | US EPA

Cesium in the Environment. Because Cs-137 bonds with chlorides to make a crystalline powder, it reacts in the environment like table salt (sodium chloride): Cesium moves easily through the air. Cesium dissolves easily in water. Cesium binds strongly to soil and concrete, but does not travel very far below the surface.
