Radon Levels in Nebraska
What this means for you
- Your area: EPA rates 53 of Nebraska's 93 classified counties 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 Nebraska'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 Nebraska, EPA's Map of Radon Zones places 53 of its 93 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.

93 of 93 counties classified
EPA classifies counties, not states. Of the 93 counties in Nebraska with a zone, 53 are in Zone 1, 24 in Zone 2 and 16 in Zone 3.
- Zone 1: Highest predicted potentialgreater than 4 pCi/L53 of 93 counties · 57.0%
- Zone 2: Moderate predicted potential2 to 4 pCi/L24 of 93 counties · 25.8%
- Zone 3: Lower predicted potentialless than 2 pCi/L16 of 93 counties · 17.2%
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 Nebraska's radon test figures by county: 93 of its 93 counties have one. Each county's share is in the county list.

What the published data says about Nebraska, in words. A zone and a share of tests describe an area, never the level in any one home.
Predicted
PredictedEPA places 53 of Nebraska's 93 counties in Zone 1, 24 in Zone 2 and 16 in Zone 3.
Zone 1 counties, A to Z, begin with Adams County, Boone County and Boyd County; the county section below lists all 53.
Compared
Calculated by Radon41157% of Nebraska's counties with a zone on file are in Zone 1, a larger 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 Nebraska on file here.
93 of the 93 counties have a published county figure; the most tests in each one's latest year were reported for Douglas County (2,171 in 2023), Lancaster County (1,920 in 2023) and Sarpy County (807 in 2023).

Questions about radon in Nebraska
Common questions9 questions, answered from the figures above
Is radon a problem in Nebraska?
EPA's Map of Radon Zones places 53 of the 93 Nebraska counties it classifies in Zone 1, the highest predicted potential, 24 in Zone 2 and 16 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.
How do I get a radon test in Nebraska?
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 Nebraska 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 stateNebraska radon program
Who does radon mitigation in Nebraska?
Radon411's Nebraska directory lists 12 certified radon companies. 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 Nebraska
Which Nebraska counties are in EPA radon Zone 1?
53 counties are in Zone 1: Adams County, Boone County, Boyd County, Burt County, Butler County, Cass County, Cedar County, Clay County, and 45 more in the county table on this page. 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.
Radon in Adams CountyRadon in Boone CountyRadon in Boyd County
Which Nebraska counties have the highest radon?
93 of Nebraska's 93 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 Nebraska are high?
CDC has published no statewide radon testing statistics for Nebraska, 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 Nebraska in?
Nebraska is in EPA Region 7: Midwest.
Do I need to test my home in Nebraska?
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 Nebraska?
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 Nebraska. 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.

Nebraska, Products
Testing and mitigation products
Whatever the figures for Nebraska 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.
