Radon Levels in Kearny County, Kansas
What this means for you
- Your area: EPA rates Kearny County Zone 1, the highest of its three radon zones. That is a prediction for the whole county, and homes with elevated levels occur in all three zones.
- Local tests: Of 2 radon tests reported to CDC for Kearny County (2022), 50.0% were at or above 4 pCi/L, EPA's action level.
- 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.
In 2022, 50.0% of the radon tests reported to CDC for Kearny County, Kansas came back at or above the EPA action level of 4 pCi/L, and the median result was 4.5 pCi/L. EPA's Map of Radon Zones places the county in Zone 1, highest predicted potential. Radon levels vary from home to home, so only a test measures the level in yours.
Predicted: EPA radon zone
EPA Zone 1: highest predicted potential
EPA predicts an average indoor of greater than 4 pCi/L (greater than 150 Bq/m³) across the county as a whole.
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.
USGS geologic potential: Low across 69% of the county's land area

Of 2 pre-mitigation tests reported to CDC, not homes in this area. CDC publishes the share in each band, not a count per band, so the per-band counts in the table are calculated by Radon411 and rounded to add up to the published total.
| Result band | Tests Calculated by Radon411 | Share Measured |
|---|---|---|
| Under 2 pCi/L | 0 | 0.0% |
| 2 to 4 pCi/L | 1 | 50.0% |
| 4 pCi/L and above | 1 | 50.0% |
Distribution of tested buildings, not this house. People testing before a sale, or because they suspect a problem, are over-represented in any reported testing data.

What these figures count
Every percentage here is a share of radon tests reported to CDC for Kearny County in 2022. It is not a share of homes in Kearny County, and it is not a random sample: it counts only the tests people chose to run and that were reported.
The shares and the median are calculated from pre-mitigation tests (2 for 2022).

Each figure is that county’s own published CDC figure for 2022, counting radon tests reported to CDC, not homes. Kearny County is this page. Nothing is averaged or combined across counties. The test count beside each county is CDC’s published number of pre-mitigation tests behind its figures. Figures from few tests can swing widely from year to year. No published CDC figure for 2022: Hamilton County, KS; Haskell County, KS. Every Kansas county’s own figure is in the Kansas county table.
CDC publishes this figure only for counties here, so there is no state or national number to compare Kearny County, Kansas with.

Kearny County, Questions
Questions about radon in Kearny County
Common questions8 questions, answered from the figures above
Are radon levels high in Kearny County?
In 2022, 50.0% of the radon tests reported to CDC for Kearny County, Kansas were at or above 4 pCi/L, and the median reported pre-mitigation result was 4.5 pCi/L. That is a share of reported tests, not of homes. EPA places Kearny County in Zone 1, highest predicted potential, a predicted average indoor screening level greater than 4 pCi/L. Homes with elevated levels occur in all three zones, so the figures describe the area, not your house. Testing is the only way to know the radon level in a specific building.
How do I get a radon test in Kearny County?
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. No certified tester listed on Radon411 names Kearny County as a service area yet. The Kansas radon program is the place to ask about certified testers and any test kit offer it runs.

Who does radon mitigation in Kearny County?
Radon411 has no certified mitigators listed for Kansas 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. Your state radon program is the place to check whether Kansas requires one.
How radon mitigation worksWhat mitigation costsKansas radon program
What EPA radon zone is Kearny County in?
EPA places Kearny County, Kansas in Zone 1, which EPA describes as highest predicted potential for the area. A zone is a prediction for the whole county and never determines whether a particular home should be tested. EPA recommends testing every home regardless of zone.
Should I test my home in Kearny County?
Yes. 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. How to test a home.
When is the best time of year to test?
EPA says short-term tests stay in the home from 2 to 90 days and that all radon tests should run a minimum of 48 hours; long-term tests stay more than 90 days. EPA's guides do not name a best season: they say radon levels tend to vary from day to day and season to season, so a long-term test is more likely than a short-term test to tell you the year-round average.
What does it cost to test?
EPA's Citizen's Guide calls testing easy and inexpensive, and EPA's Home Buyer's and Seller's Guide says passive short-term and long-term devices are generally inexpensive, while active devices may cost more. No national average price is published for this, so Radon411 does not give one. What testing costs.
Which counties border Kearny County?
Kearny County borders 7 counties, derived from Census county geometry. Radon potential follows geology rather than county lines, so a bordering county's report can be relevant.

- 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.
