Radon is an invisible radioactive gas found in soil and rocks. It seeps into your home through cracks in the foundation, walls and joints. Radon is the leading cause of lung cancer in non-smokers and the second leading cause in smokers. Based on United States Environmental Protection Agency (EPA) estimates lung cancer due to radon exposure claims about 21,000 US lives annually.
