Radon is a naturally occurring radioactive gas that is formed when uranium decays in the soil. Uranium is in geological formations throughout North Carolina. When homes or other buildings are built on top of these geological formations, radon is pulled into the home and can concentrate to dangerous levels. Exposure to radon gas has been found to cause lung cancer.
Every home in North Carolina is prone to having a level of radon gas and the N.C. Radon Program recommends that ALL HOMES be tested. This includes apartments, mobile homes and homes with and without basements. Radon gas is natural and comes from the l decay of uranium found in rocks, soil and building materials such as concrete. Testing your home for radon gas will help you determine the amount of radon you may be breathing.
Testing your home for radon is as simple as opening a package, placing a radon detector in a designated area, and after the prescribed number of days (usually 2-7 days), sealing the detector back in the package and mailing it to a lab for evaluation. Radon is measured in picocuries per liter of air (pCi/L), a measurement of radioactivity. The U.S. EPA and the Centers for Disease Control and Prevention recommend that homes with radon levels at or above 4 pCi/L be repaired to reduce the amount of radon entering the indoor air.
