Why should I test my home?

Although there are no immediate symptoms, long-term exposure to radon can cause cellular damage in the lungs that can lead to lung cancer.

The United States Environmental Protection Agency, Surgeon General, American Lung Association, American Medical Association, and the National Safety Council recommend testing your home for radon because testing is the only way to know if your home has radon.

Contact your local county health department or call 1-800-383-5992 to purchase a do-it-yourself, low-cost test kit.

If your home is being tested for radon as part of a real estate transaction see the EPA "Home Buyer's and Seller's Guide" booklet below or the "Iowa Home Buyer's and Seller's Factsheet" under the Resources section of our website for more information.
