- Polonium is a chemical element with the
symbol Po and atomic number 84, discovered in 1898 by Marie and Pierre
Curie.
- Polonium is the first element of the
periodic table for which all of its isotopes are radioactive. It
is a
very rare natural element, Gen Roessler existing in uranium ores in
amounts of about 100 µg per ton of ore.
- There are seven polonium isotopes that
arise from the naturally occurring thorium (212Po, 216Po),
actinium
(211Po, 215Po), and uranium (210Po,214Po, 218Po) decay
series. Because none of these isotopes has a long
half time, they do
not accumulate in the natural environment to any significant extent
polonium metal is silvery gray in color and interacts to varying extent
with O2 depending on the temperature. Practically, the metal can be
maintained only under inert atmosphere.
- Because the specific activity of 210Po is
so high (166 TBq g-1), milligram quantities will exist
at
temperatures well above ambient. The electron configuration of
neutral polonium resembles those of selenium
and tellurium
Polonium-210 is widely found in small amounts in the earth’s crust. This
is because it is produced during the decay of another natural element
called uranium-238.
- It can also be produced by processing
uranium ores or
minerals, but the amount produced is very small.
Very small amounts of polonium-210 are found in food.
- Polonium-210 is used mainly in machines to
get rid of static electricity. Machines used to make paper, sheet
plastics and synthetic fibers often use this element.
- Polonium-210 is also used in brushes to
remove dust from photographic films and camera lenses. It can be used to
make atomic weapons Polonium-210 is found almost everywhere in nature in
low levels, so exposure cannot be completely prevented.
- The best way to limit exposure is to not
breathe tobacco smoke. Radiation from polonium-210
cannot go through
outer dead layers of skin or through clothing. Eyes or open wounds must
be carefully protected.
- Polonium is an alpha-emitter, and is used
as an alpha-particle source for scientific research in the form of a
thin film
on a stainless steel disc. It is also used as a heat source
in space equipment. |
