역사

This radioactive metal was also known as radium-F. The name of Polonium derives from “Poland”, the native country of Marie Sklodowska Curie. It was discovered by Marie Curie (Paris, France) in 1898, from its radioactivity. It was independently found by the German chemist Willy Marckwald in 1902 and called radiotellurium. The longest halflife associated with this unstable element is 102 year 209Po.
