	It's Elemental - The Element Polonium
		Due to its scarcity, polonium is usually produced by bombarding bismuth-209 with neutrons in a nuclear reactor.
		Polonium can be used to eliminate static electricity in machinery that is caused by processes such as the rolling of paper, wire or sheet metal, although other materials which emit beta particles are more commonly used for this purpose.
		Polonium is also used in brushes for removing dust from photographic films, although the polonium must be carefully sealed to protect the user from contamination.

	Polonium
		This isotope of polonium has a half life of almost 140 days, and a neutron initiator using this material needs to have the polonium, which is generated in a nuclear reactor, to be replaced frequently.
		The polonium project was undertaken by MCC at the company's Central Research Department in Dayton, Ohio, in September 1943, and became known as the Dayton Project.
		Initially, the recovery of polonium was attempted from naturally occurring sources such as lead-containing wastes from uranium, vanadium, and radium refining operations.

		The death of Aleksandr Litvinenko from polonium poisoning is the first such case in history; it was also the first case of someone dying from the acute effects of alpha radiation from any source.
		Polonium, when absorbed orally, tends to distribute widely through the tissues of the body, approximating whole body radiation exposure.
		Polonium is excreted fairly quickly, its effective half-life in the body is about 30 days (mostly due to excretion, but also due to radioactive decay).

	C&EN: IT'S ELEMENTAL: THE PERIODIC TABLE - POLONIUM
		Polonium, Marie's dear polonium, number 84 on the periodic chart, was the first element discovered via its radioactivity.
		Marie, writing in December 1904, explained why: "Polonium, when it has just been extracted from pitchblende, is as active as radium, but its radioactivity slowly disappears." We know now that polonium's most stable isotope has a half-life of 138.39 days compared with the 1,620 years of radium's longest lived isotope.
		Polonium has had a minor flare of celebrity in debate between creationists--who believe the universe, Earth, and the life upon it were created some 6,000 years ago during a seven-day period called Genesis Week--and those who subscribe to the Big Bang theory.

	Polonium - Wikipedia, the free encyclopedia
		Polonium (IPA: /pə(ʊ)ˈləʊniəm/) is a chemical element in the periodic table that has the symbol Po and atomic number 84.
		By means of radiometric methods such as gamma spectroscopy (or a method using a chemical separation followed by an activity measurement with a non-energy-dispersive counter), it is possible to measure the concentrations of radioisotopes and to distinguish one from another.
		Alpha particles emitted by polonium material are absorbed by the body and will damage organic tissue easily if ingested or absorbed (though they do not penetrate the epidermis and hence are not hazardous if the polonium is outside the body).
