Health effects of polonium Polonium kann daher bei der Aufarbeitung von Pechblende gewonnen werden (1000 Tonnen Uranpechblende enthalten etwa 0,03 Gramm Polonium). Dabei reichert es sich zusammen mit Bismut an. Von diesem Element kann man es anschließend mittels fraktionierter Fällung der Sulfide (Poloniumsulfid ist schwerer löslich als Bismutsulfid) trennen.

The element normally exhibits six allotropes and four oxidation states. It reacts with carbon , halogens , nitrogen , silicon , and hydrogen . When exposed to moist air, it forms oxides and hydrides that can expand the sample up to 70% in volume, which in turn flake off as a powder that is pyrophoric .
