Polonium is a rare radioactive element discovered in 1898 by Marie and Pierre Curie. It is a metal that exists in solid form and belongs to the group of poor metals in the periodic table. Polonium is obtained through irradiation of bismuth with neutrons or protons since it is only found naturally in trace amounts in uranium ores. Its main uses are in compact heat sources for space probes and removing static electricity from photographic film through its radioactive emissions.

14. METHODS FOR OBTAINING
14
polonium is a very rare element in nature because of the short half-life of
all its isotopes. it is found in uranium ores at about 0.1 mg per metric ton
(1 part in 1010),which is approximately 0.2% of the abundance of
radium. the amounts in the earth's crust are not harmful. polonium has
been found in tobacco smoke from tobacco leaves grown with
phosphate fertilizers.because of the small abundance, isolation of
polonium from natural sources is a very tedious process. the largest
batch was extracted in the first half of the 20th century by processing 37
tonnes of residues from radium production. it contained only 40 ci (9 mg)
of polonium-210.nowadays, polonium is obtained by irradiating bismuth
with high-energy neutrons or protons

16. UTILITY
16
Polonium releases a great deal of energy during its radioactive
breakdown. This has led to the development of compact heat sources
for specialized purposes, such as use on space probes.
Radiation is used to remove static electricity from photographic film.
Static electricity consists of electric charges that collect on the outside
of a surface. In film, they can reduce the clarity of a picture. The
radiation polonium releases creates electrical charges in the air
around it. These charges combine with those on the film, neutralizing
them and preventing damage to the film.
