Radon is an odorless, tasteless and invisible gas produced by the decay of naturally occurring uranium in soil and water. Radon is a form of ionizing radiation and a proven carcinogen. If you are selling a home, or purchasing one, you will be asked to disclose any known knowledge of radon. Radon tests are strongly encouraged when one purchases a property and repeatedly after that to be safe.
It can be dangerous: EPA estimates that about 20,000 lung cancer deaths each year in the U.S. are radon-related. Exposure to radon is the second leading cause of lung cancer after smoking. Read here for more information.
Talk with a radon tester or a radon mitigator for more information. If your level is higher than the level the state is unsafe, they would probably recommended radon mitigation.
From the EPA: “For most Americans, their greatest exposure to radon is in their homes; especially in rooms that are below grade (e.g., basements), rooms that are in contact with the ground and those rooms immediately above them… It’s never too late to reduce your risk of lung cancer. Don’t wait to test and fix a radon problem. If you are a smoker, stop smoking. Consider quitting. Until you can quit, smoke outside and provide your family with a smoke-free home.
