  1. Polonium By: Jared Poist

  2. Discovery • Founded by Marie Curie (in Paris, France) back in 1898 • At the time she was trying to determine the cause of radioactivity in pitchblende • Element was named after Poland

  3. Properties • Orientation: silvery, grey metal • Melting point: 527 K (489.2° F) • Boiling point: 1235 K (1763.6° F) • Atomic number: 84 • Atomic mass: 209

  4. Where Can It Be Found? • Polonium mainly occurs in uranium • 100 micrograms of polonium for every ton of uranium • Polonium has also been spotted in tobacco smoke

  5. Uses • Alpha radiation • Heat source for space crafts • Creates neutrons when mixed with beryllium • Can remove static charge from textiles and dust from photographic film
