This page contains a downloadable PDF of EPA Region 3's Mid-Atlantic Radon Measurements Map for determining an area's radon potential.
- Region 3 compiled available radon data from state radon programs to create this map. The data represents the average of the test results grouped by zip code. Using both the Radon Zone Map and Mid-Atlantic Radon Measurements Map you can determine the radon potential in your area. However, you should use these maps for informational purposes only; all homes should be tested regardless of geographic location, radon zone or local test data.
