Radon is a colorless, odorless, tasteless, and chemically inert radioactive gas. It is formed by the natural radioactive decay of uranium in rock, soil, and water. Naturally existing, low levels of uranium occur widely in Earth's crust. It can be found in all 50 states. Unless you test for it, there is no way of telling how much is present.

"The U.S. Environmental Protection Agency has numerous publications covering various aspects of radon and indoor air quality. For a list of these publications, please visit http://www.epa.gov/iaq/pubs/index.html"

Radon Proficiency

The EPA stopped operating its National Radon Proficiency Program (RPP) on October 1, 1998. That program was designed to test radon contractors and provide a measure of quality control. The RPP is now privately run. See the EPA's Web site regarding the RPP for information on how to identify qualified contractors.
Many states certify or license radon contractors. Call your state radon office for information about qualified service providers in your state.
If you plan to fix the problem in your home yourself, you should first contact your state radon office for EPA's technical guide, "Radon Reduction Techniques for Detached Houses."
