This element Po(84) was the first one discovered by the Curies while they were investigating the cause of pitchblenderadioactivity (1898). The pitchblende, after removal of the radioactive elements uranium and thorium (Th), was more radioactive than both the uranium and thorium put together. This spurred the Curies on to find additional radioactive elements. The Curies first separated out polonium from the pitchblende1), and then within a few years, also isolated radium.
1) The type locality for this ore is Jáchymov in the Czech Republic, from where F.E.Brückmann described the mineral in 1727.
Pitchblende from the Johanngeorgenstadt deposit in Germany was used by M.Klaproth in 1789 to discover the element uranium.
