Want to make sure your family is not exposed to the second leading cause of lung cancer? You'll want to consider testing your home for radon. The US Surgeon General and the Environmental Protection Agency advise testing for this naturally occurring substance that can seep into homes from underground.
You may find a free or reduced price test kit available from your state, or you can buy a convenient radon test kit at the local home improvement store. Even if your home was tested in the past or built with radon resistant methods in recent years, the EPA suggests you may want to test again from time to time, especially if anything has changed in your home environment.
Homes in any part of the country could potentially be affected by radon. You can start with the EPA's website for basic information
about this carcinogen and what to do if you detect it above action levels.
