It was first reported, though there's some argument whether it really was the discovery, in 1899, when it was separated from the ores, the metal ores, that were used for separating Radium and eventually Polonium. These are radioactive ores that I think originally came from somewhere in the Czech Republic but in middle Europe and by very careful chemical treatment they removed these elem...
