82 of 82 counties classified

EPA classifies counties, not states. Of the 82 counties in Mississippi with a zone, 8 are in Zone 2 and 74 in Zone 3.

  • Zone 2: Moderate predicted potential2 to 4 pCi/L8 of 82 counties · 9.8%
  • Zone 3: Lower predicted potentialless than 2 pCi/L74 of 82 counties · 90.2%

An EPA radon zone predicts a whole county. It is not intended to determine whether any individual home should be tested: homes with elevated levels occur in all three zones, and EPA recommends testing every home regardless of zone.

How radon mitigation worksWhat mitigation costsRadon professionals in Mississippi

Which Mississippi counties have the highest radon?

82 of Mississippi's 82 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 Mississippi are high?

CDC has published no statewide radon testing statistics for Mississippi, 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 Mississippi in?

Mississippi is in EPA Region 4: Southeast.

Do I need to test my home in Mississippi?

Yes, wherever you live in Mississippi. 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.
