Reduce Radon Levels in Your Home

Radon is the leading cause of lung cancer for non-smokers and the second leading cause of lung cancer for the general population. The Surgeon General and EPA recommend testing for radon and reducing radon in homes that have high levels. Fix your home if your radon level is confirmed to be 4 picocuries per liter, pCi/L, or higher. Radon levels less than 4 pCi/L still pose a risk, and in many cases may be reduced. If you smoke and your home has high radon levels, your risk of lung cancer is especially high.

Select a State Certified and/or Qualified Radon Mitigation Contractor

Choose a qualified radon mitigation contractor to fix your home. Start by checking with your state radon office. Many states require radon professionals to be licensed, certified, or registered. You can also contact private radon proficiency programs for lists of privately certified radon professionals in your area. See pages 4 and 17 for more information.

Your costs may vary depending on the size and design of your home and which radon reduction methods are needed. Get an estimate from one or more qualified radon mitigation contractors. Hundreds of thousands of people have reduced radon levels in their homes.
