Tarix
Polonium was discovered by Marie and Pierre Curie in 1898 in Paris.

This element was the first one discovered by the Curies while they were investigating the cause of pitchblende radioactivity.

The dangers of working with radioactive elements were not known when the Curies made their discoveries.

Applications
Polonium is used to eliminate static electricity produced during processes such as rolling paper, wire and sheet metal.

Polonium can be mixed or alloyed with beryllium to provide a source of neutrons.

It is also used in anti-static brushes to eliminate dust on photographic film.
Polonium is highly dangerous and radioactive
