Radon is a colorless and odorless gas that is the second leading cause of lung cancer. A 2016 report by the US Environmental Protection Agency noted that approximately one in 15 homes in the US contains elevated levels of radon. Radon is produced by the natural breakdown of uranium, rock soil, and water that seeps into a home through cracks and holes in the foundation. More common in older homes, radon can still be present in new construction if radon-resistant features weren’t installed.
If the level of radon in a home is above a certain amount, there are ways to reduce the level of gas. The EPA recommends that homeowners test their homes before listing them on the market, and that buyers always test homes they want to buy. Visit the EPA’s website to learn more about radon, or contact your state radon office to find out if the area where you’re searching has high levels of radon in homes.
