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 can be pulled into the home through small cracks or through the water supply and can concentrate to dangerous levels. Exposure to radon gas has been found to cause lung cancer. Exposure to radon in the home is responsible for an estimated 20,000 lung cancer deaths each year. Radon is an odorless, colorless, and tasteless gas that can only be reliably detected by testing.
For these reasons a radon test is recommended on all homes by KO Home Inspections, the U.S. EPA, and the NC Radon Program. 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.
KO Home Inspections has local certified radon professionals that use digital electronic meters to take measurements. The testing period lasts 48 hours with the results available that evening. Testing only costs $150 for most homes so ask for a radon test with your home inspection or request a stand alone radon test.
