Polonium exists both naturally, as a by-product of the radioactive decay of naturally occurring Uranium 238, and from the 'fall out' of nuclear accidents and the hundreds of atomic bomb tests last century. All plants, including those we eat and feed to livestock, MAY absorb extremely low concentrations of polonium from the environment. The tobacco plant is no exception. Polonium has also been detected in fish.

Another potential source of polonium in plants is from phosphate fertilizers. The phosphate ores used have the ability to absorb and trap radioactive contaminants and this is another industrial use of the ores. (Others include the treatment of drinking water and as a whitener in toothpaste!)

No commercially viable method is known to eliminate polonium from cigarettes nor from the plants (and fish) in the human food chain, where the levels are considered 'safe'. However, there are many other health risks associated with smoking.
