Radon is a cancer-causing, radioactive gas. You cannot see, smell or taste radon. But it still may be a problem in your home.  When you breathe air containing radon, you increase your risk of getting lung cancer.  In fact, the Surgeon General of the United States has warned that radon is the second leading cause of lung cancer in the United States today.  

 

If you smoke and your home has high radon levels, your risk of lung cancer is especially high. You should test for radon. Testing is the only way to find out your home's radon levels. The EPA and the Surgeon General recommend testing all homes below the third floor for radon.
