Radon is a naturally occurring, radioactive gas that is produced from the radioactive decay of radium-226, one of the decay products of uranium-238. The primary hazard from radon is its decay products, which are referred to as radon progeny. Radon progeny are short-lived radioactive decay products of radon gas.
Radon is a colorless, odorless, radioactive gas which is heavier than air. It comes from the decay of radium in soil. Radon lingers in low areas such as basements and crawl spaces under buildings and can build up to high concentrations in unventilated areas. If inhaled for long periods of time, it may cause lung cancer.

A radioactive element. The element is a chemically inert gas that is produced from the radioactive decay of radium, which in turn is created by the radioactive decay of uranium. As such, radon is found naturally in certain geological formations such as granite where uranium can occur naturally.
a heavy radioactive gaseous element formed by the disintegration of uranium and thorium. It is colorless, tasteless, and odorless and found commonly in bedrock and sediments. All rocks and soil, including the limestone found in Mammoth Cave, contain varying amounts of radon.
Radon is a naturally occurring, odorless, tasteless radioactive gas. It is produced from the radioactive decay of radium, which is formed from the decay of uranium. Because radon is inert and thus not chemically bound or attached to other materials, it can move freely through very small spaces, such as those between particles of soil and rock. Radon migrates from soil and rock through cracks in the basement or slab and into the indoor air. It can also migrate into groundwater and be released into household air when the tap is on or the shower is running. The EPA and the Surgeon General estimate that exposure to radon in homes and buildings causes between five thousand and twenty thousand cases of lung cancer each year. (Marinelli and Bierman-Lytle, 1995, p. 247)

While not a mandated health standard, this level is a guideline for people to use in assessing the seriousness of their exposure to airborne radon. Until such time as the federal standard for radon in water is finalized, the DES(Department of Environmental Services) and DHHS (Department of Public Health Services) suggest that homeowners investigate water treatment for the removal of radon if the concentration of radon in their drinking water exceeds an average of 2,000 pCi/L (10,000 pCi/L in Massachusetts).
