Radon Risk Lookup by ZIP Code

Enter your ZIP code to see the EPA radon zone for your area. This is a screening tool -- not a substitute for testing your actual home.

EPA radon zone maps are county-level predictions based on geology, not individual home measurements. Radon levels can vary significantly between neighboring houses. The ONLY way to know your home's radon level is to test it. Short-term test kits cost $15-$30 and are available from most home improvement stores or your state health department.
