Polonium can be found in uranium ores at about 0.1 mg per metric ton (1 part in 10 10), [51] [52] which is approximately 0.2% of the abundance of radium. The amounts in the Earth's crust are not harmful. Polonium has been found in tobacco smoke from tobacco leaves grown with phosphate fertilizers. [53] [54] [55]

Polonium-210 (210 Po, Po-210, historically radium F) is an isotope of polonium. It undergoes alpha decay to stable 206 Pb with a half-life of 138.376 days (about 4 + 1 ⁄ 2 months), the longest half-life of all naturally occurring polonium isotopes ( 210–218 Po). [ 1 ]
