Strontium-90 can be inhaled, but ingestion in food and water is the greatest health concern. Once in the body, Sr-90 acts like calcium and is readily incorporated into bones and teeth, where it can cause cancers of the bone, bone marrow, and soft tissues around the bone. Because Sr-90 acts like calcium, milk monitoring will be important after a ...

Key Properties. Strontium is softer than calcium and tends to decompose actively in water. Should be stored in kerosene to prevent oxidation. Fine strontium powder ignites spontaneously in air. The appearance of freshly cut strontium surface is silvery, but tends to oxidize quickly and appears yellowish. Does not absorb nitrogen below 380 °C.
