GovGab: “Is a colorless, odorless, deadly gas seeping into your home? Unless you test your home for radon, you’ll never know. It’s estimated that one in 15 homes has elevated levels of radon…Radon in your home is a serious matter. Radon is the number one cause of lung cancer among non-smokers, and overall it is the second leading cause of lung cancer. It’s responsible for about 21,000 lung cancer deaths each year.”
