What are the toxicological properties of Polonium-210?
Polonium-210's toxicity stems from its intense radioactivity. Just one microgram can deliver a fatal dose. Its alpha radiation is highly ionizing but has low penetration power; thus, it poses a significant health risk only when ingested or inhaled. The biological half-life of polonium-210 in humans is approximately 50 days, during which it can severely damage biological tissues.
