Radon is a naturally occurring radioactive gas that can cause lung cancer.

You can’t see or smell radon. Testing is the only way to know your level of exposure.

 Radon is the number one cause of lung cancer among non-smokers, according to EPA estimates. Overall, radon is the second leading cause of lung cancer. On January 13, 2005, Dr. Richard H. Carmona, the U.S. Surgeon General, issued a national health advisory on radon.

The National Radon Program Services at Kansas State University has test kits available to purchase online at or call 1-800-SOS-RADON (1-800-767-7236).

Who Should I Hire to Test or Fix My Home?

If you are interested in finding a service provider to test for radon or mitigate (fix) your home, contact your state radon program for help in finding qualified professionals in your state.

Currently, EPA requires state receiving indoor radon grants to maintain and provide the public with a list of only those radon service providers who are credentialed either through:

    1. An existing state-run process established under a state’s regulatory requirements for credentialing radon service providers (e.g., state license), or
    2. One of the two currently-recognized national radon proficiency programs:
