Source
Radon (Rn) is a radioactive gaseous chemical element formed in the atomic disintegration of radium. Radon 222 is one of the radionuclides of most concern when found in drinking water. It is a naturally occurring isotope, but can also come from man-made sources. All radionuclides are considered carcinogens, but the organs they target vary. Since radon 222 is a gas, it can be inhaled during showers or while washing dishes. There is a direct relationship between radon 222 and lung cancer. Under the NIPDWR (national interim primary drinking water regulations), the MCL (maximum contamination level) for radon 222 is set at 15 pCi/L (see radium for explanation of how radiation is measured).
Treatment
Radon is easily removed by aeration, since it is a gas. Carbon filtration is also very effective in removing radon.
