Georgia Radon Map and Levels by County

Georgia's counties span all three EPA radon zones. Homes with elevated levels occur in all three zones, so only a test measures yours.

Predicted: EPA radon zone

159 of 159 counties classified

EPA classifies counties, not states. Of the 159 counties in Georgia with a zone, 4 are in Zone 1, 55 in Zone 2 and 100 in Zone 3.

  • Zone 1: Highest predicted potentialgreater than 4 pCi/L4 of 159 counties · 2.5%
  • Zone 2: Moderate predicted potential2 to 4 pCi/L55 of 159 counties · 34.6%
  • Zone 3: Lower predicted potentialless than 2 pCi/L100 of 159 counties · 62.9%

An EPA radon zone describes predicted potential across a whole county. It is not intended to determine whether any individual home should be tested, and homes with elevated levels occur in all three zones. EPA recommends testing every home regardless of zone, and testing is the only way to know the radon level in a specific building.

EPA's Map of Radon Zones places 4 of the 159 Georgia counties it classifies in Zone 1, the highest predicted potential, 55 in Zone 2 and 100 in Zone 3. An EPA radon zone describes predicted potential across a whole county.

Which Georgia counties are in EPA radon Zone 1?

4 counties are in Zone 1: Cobb County, DeKalb County, Fulton County, Gwinnett County. Zone 1 is EPA's class for highest predicted potential, a predicted average indoor screening level greater than 4 pCi/L. A zone is a prediction for a county, not a measurement of any home.

How do I get a radon test in Georgia?

EPA says you can test your home yourself or hire a qualified radon test company, and that either approach takes only a small amount of time and effort. The Georgia radon program is the place to ask about certified testers and any test kit offer it runs.

Who does radon mitigation in Georgia?

Radon411's Georgia directory lists 3 radon businesses for testing, mitigation or both, each with the licensing list it was read from. EPA recommends having a qualified contractor fix a home with a radon problem, because lowering high radon levels takes technical knowledge and special skills, and some states require the work to be done by a licensed or certified professional.

How radon mitigation worksWhat mitigation costsRadon professionals in Georgia

Which Georgia counties have the highest radon?

159 of Georgia's 159 counties have an EPA radon zone published here. Radon411 will not rank counties on data it does not hold, and a zone is a prediction for an area rather than a measurement of any building.

What share of radon tests in Georgia are high?

CDC has published no statewide radon testing statistics for Georgia, so we cannot give a figure. Where CDC does publish one, the percentage describes radon tests reported to CDC, not homes.

Which EPA region is Georgia in?

Georgia is in EPA Region 4: Southeast.

Do I need to test my home in Georgia?

Yes, wherever you live in the state. Testing is the only way to know the radon level in a specific building. EPA recommends fixing a home when the radon level is 4 pCi/L or higher. EPA recommends considering a fix when the level is between 2 and 4 pCi/L.

Why does this page show coverage rather than one radon level for Georgia?

A statewide figure averages counties with very different geology and very different numbers of reported tests, so it hides more than it shows. The county report is the level at which the EPA zone, the geologic potential and the reported testing statistics are actually published, which is why the county table above links to every one of them.

The figures above, said in words

What the published data says about Georgia, in words. A zone and a share of tests describe an area, never the level in any one home.

    • Predicted

      Predicted

      EPA places 4 of Georgia's 159 counties in Zone 1, 55 in Zone 2 and 100 in Zone 3.

      Zone 1 counties, A to Z, begin with Cobb County, DeKalb County and Fulton County; the county section below lists all 4.

    • Compared

      Calculated by Radon411

      3% of Georgia's counties with a zone on file are in Zone 1, a smaller share than across all U.S. counties (34%). It is a share of counties, not of land, people or homes.

  • Reported tests

    Measured

    CDC has no statewide testing figure for Georgia on file here.

    139 of the 159 counties have a published county figure; the most tests in each one's latest year were reported for Fulton County (4,858 tests over 2008 to 2017, laboratory), Gwinnett County (4,187 tests over 2008 to 2017, laboratory) and DeKalb County (3,475 tests over 2008 to 2017, laboratory).
