Hazards and Risks

Hazards and risks associated with radium: radium does not occur to any significant extent in the biosphere and so normally should never present a risk. Radium is studied in a few nuclear research laboratories where its high radioactivity requires special handling techniques and precautions. Its high radioactivity is far more important than any chemical toxicity but from a chemical point of view its hazards are similar to those of barium.
