Radon is a colorless, odorless naturally occurring gas that causes lung cancer. In fact it is the second leading cause of lung cancer in the United States, and it is the number one cause of lung cancer in non-smokers. Radon is estimated to be responsible for about 21,000 deaths in the United States annually. Radon comes from the breakdown of uranium in soil, rock and water. Many homes have radon entering the home through cracks and voids in the foundation (see the picture to the right). The radon in your home’s indoor air can also come your water supply, especially if you have a private well. Levels of radon can vary wildly from home to home, neighborhood to neighborhood and county to county.
From the map below, many counties we serve are either in a Zone 1 or 2 which means many of the homes in those areas are at risk of having elevated levels of radon. Since we cannot see, smell or taste radon the only way to find radon is by testing. The EPA recommends that every home be tested for radon. The EPA recommends that homes with a level of greater than 4 pCi/L be mitigated by a licensed radon mitigation company, homes that have less than 4 pCi/L should takes measures to reduce the levels of radon within the home.
