Polonium-210 is a very strong emitter of alpha particles. A single gram of polonium-210 creates 140 Watts of heat energy and is being considered as a lightweight heat source for thermoelectric power for spacecraft. Polonium-210 has a half-life of 138.39 days. Polonium's most stable isotope, polonium-209, has a half-life of 102 years.

Russell Hoban – rutenium och holmium (”Polly” = polonium). 16. Dorothy Parker – protaktinium. (Här var jag lite för snål med DRT, tycker jag.)

Knutsi writes "InformationWeek is reporting that Polonium 210, the radioactive material used to poison former KGB spy Alexander Litvinenko is not as hard to get your hands on as some have previously stated. American family business United Nuclear is actually selling the stuff, and other equally exo Uranium Ore samples are useful as check sources for testing Geiger Counters. No chemical or spectral analysis is performed on the radioactive ore sample. So the source of the ore's radioactivity is not determined and may be any of, or any number of radioactive elements such as uranium, thorium and potassium and any of their decay products such as Polonium (Po), a radioactive, silvery-gray or black metallic element of the oxygen group (Group 16 [VIa] in the periodic table).

Being produced during the decay of naturally occurring uranium-238, polonium-210 is widely distributed in small amounts in the earth's crust. Although it can be produced by the chemical It is difficult to get hold of polonium-210 unless the individual has access to a nuclear facility. Only around 100g of the substance is manufactured in nuclear reactors around the world annually. Polonium is the fundamental reference point thanks to which you can understand who is behind this crime.

Polonium can be found in uranium ores at about 0.1 mg per metric ton (1 part in 10 10), 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.

Polonium is a radioactive element that is used industrially as an anti-static material. It is difficult to get hold of and not used regularly by research scientists, but very small traces of it occur naturally. The metal is usually made by bombarding the element bismuth with neutrons.
