Radon Levels in Arkansas
What this means for you
- Your area: None of Arkansas's 75 classified counties is in EPA Zone 1, the highest of its three radon zones. Zones are predictions for whole counties, and homes with elevated levels occur in all three zones.
- Local tests: CDC publishes Arkansas's radon test results by county. Open your county below to see its figures.
- Your home: The only way to know your home’s level is to test it.
pCi/L (picocuries per liter) is the unit radon is measured in. EPA recommends fixing a home at 4 pCi/L or above, its action level.
For Arkansas, EPA's Map of Radon Zones places 0 of its 75 classified counties in Zone 1, highest predicted potential, a prediction for each county as a whole. Radon levels vary from home to home, so only a test measures the level in yours.

75 of 75 counties classified
EPA classifies counties, not states. Of the 75 counties in Arkansas with a zone, 14 are in Zone 2 and 61 in Zone 3.
- Zone 2: Moderate predicted potential2 to 4 pCi/L14 of 75 counties · 18.7%
- Zone 3: Lower predicted potentialless than 2 pCi/L61 of 75 counties · 81.3%
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.
This is a county-level geologic prediction. It is not a measurement of any address, and houses with elevated radon are found in all three zones.

Measured: tests reported to CDC
CDC publishes Arkansas's radon test figures by county: 61 of its 75 counties have one. Each county's share is in the county list.

What the published data says about Arkansas, in words. A zone and a share of tests describe an area, never the level in any one home.
Predicted
PredictedEPA places 14 of Arkansas's 75 counties in Zone 2 and 61 in Zone 3.
No Arkansas county is in Zone 1.
Compared
Calculated by Radon4110% of Arkansas'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
MeasuredCDC has no statewide testing figure for Arkansas on file here.
61 of the 75 counties have a published county figure; the most tests in each one's latest year were reported for Benton County (98 in 2017), Pulaski County (63 in 2017) and Washington County (41 in 2017).

Questions about radon in Arkansas
Common questions8 questions, answered from the figures above
Is radon a problem in Arkansas?
EPA's Map of Radon Zones places 0 of the 75 Arkansas counties it classifies in Zone 1, the highest predicted potential, 14 in Zone 2 and 61 in Zone 3. 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.
Who does radon mitigation in Arkansas?
Radon411 has no certified mitigators listed for Arkansas yet. 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 Arkansas
How do I get a radon test in Arkansas?
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 Arkansas radon program is the place to ask about certified testers and any test kit offer it runs.
How to test a homeFree and low-cost kits by stateArkansas radon program
Which Arkansas counties have the highest radon?
75 of Arkansas's 75 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 Arkansas are high?
CDC has published no statewide radon testing statistics for Arkansas, 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 Arkansas in?
Arkansas is in EPA Region 6: South Central.
Do I need to test my home in Arkansas?
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 Arkansas?
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.
What these figures mean if you own, buy, sell or rent
The zone counts on this page describe counties across Arkansas. They are predictions for areas, and none of them measures your building.
- How to test a home
If you own your home
Test the lowest lived-in level; a short-term kit screens in days, a long-term kit reflects the year.
- Buying a house: radon guide
If you are buying
Ask for past results and any system's post-mitigation test, and test during the sale.
- Selling a house: radon guide
If you are selling
Testing before you list puts the timing in your hands; disclosure rules differ by state.
- Radon in rental homes
If you rent, or rent out a home
A tenant can test; a fix is the owner's to make, and duties differ by state.

Arkansas, Products
Testing and mitigation products
Whatever the figures for Arkansas show, only a test tells you about one home.
Testing
- Short-term test kitsPassive detectors exposed for a few days under closed-building conditions, then analyzed by a lab.
- Long-term test kitsDetectors exposed for more than 90 days, for a closer picture of the annual average.
- Continuous monitorsPowered devices that log radon on a repeating cycle, often used for transaction tests.
- Digital detectorsConsumer devices that display a running radon reading without a lab.
- Water radon testsKits for radon dissolved in well water, analyzed by a lab.
Mitigation
- Mitigation fansThe inline fan that keeps a soil depressurization system running, sized by the installer.
- System indicatorsU-tube manometers and fan alarms that show whether a mitigation system is still working.
- Sealing materialsCrack, joint and sump sealing used alongside a mitigation system, not instead of one.
