Radon is a naturally occurring cancer-causing, radioactive gas that you can't see, smell or taste.
Radon is estimated to cause 14,000 - 30,000 deaths each year. In fact, the Surgeon General has warned that radon is the second leading cause of lung cancer in the United States today. Only smoking causes more lung cancer deaths. If you smoke and your home has high radon levels, your risk of lung cancer is even greater.
