Are There Foods That Contain Cesium? | Healthy Living

However, if it is radioactive, cesium can enter plants if it falls on their leaves, according to the Agency for Toxic Substances and Disease Registry. Under normal conditions, people consume very small amounts of stable cesium through the plants and animals they eat and the water they drink. Radioactive cesium is more of a concern.
