Hazards and Risks

Hazards and risks associated with strontium: chemically, strontium resembles calcium and the human body does a poor job of distinguishing the two. It is therefore absorbed by the body and stored in the skeleton in places where calcium should be. This also happens with radioactive 90Sr which produced by above-ground nuclear explosions in the 1950s. Strontium-90 regrettably is widely spread in the environment.
