Radon Levels in Queens County, New York
What this means for you
- Your area: EPA rates Queens County Zone 3, the lowest 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 11 radon tests reported to CDC for Queens County (2023), 9.1% 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 2023, 9.1% of the radon tests reported to CDC for Queens County, New York came back at or above the EPA action level of 4 pCi/L, and the median result was 0.5 pCi/L. EPA's Map of Radon Zones places the county in Zone 3, lower predicted potential. Radon levels vary from home to home, so only a test measures the level in yours.
Predicted: EPA radon zone
EPA Zone 3: lower predicted potential
EPA predicts an average indoor of less than 2 pCi/L (less than 75 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.

Of 11 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 | 9 | 81.8% |
| 2 to 4 pCi/L | 1 | 9.1% |
| 4 pCi/L and above | 1 | 9.1% |
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.

PredictedEPA places Queens County in Zone 3, lower predicted potential, as it does 14 other counties of New York's 62.
Of the 4 bordering counties, EPA places Bronx County, Kings County, Nassau County and New York County in Zone 3.
Reported tests
MeasuredCDC has annual figures for Queens County for 10 years, 2014 to 2023. In 2023, 9.1% of 11 reported tests were at or above 4 pCi/L.
Across those years the share ranged from 0.0% (2022) to 33.3% (2021). Few tests in a year can move it a long way.

What these figures count
Every percentage here is a share of radon tests reported to CDC for Queens County in 2023. It is not a share of homes in Queens 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 (11 for 2023).

Tests behind these figures
10.6 tests a year on average
- Every figure is a five-year rolling average: the average result is the rolling average of each year's mean, and the test count is an average per year.
- The data only include tests requested through the NYSDOH Radon Program, and therefore may not capture all radon tests performed in a county.
- The data include both screening tests and post-mitigation tests, as it is not always possible to tell them apart.
- Radon testing by homeowners is optional in New York, so the values may not be representative of every home in the county.
- These figures describe tests reported to the New York State Department of Health in this area. They count a different set of tests than CDC's figures and are not a reading of any one home.
Measured: New York State Department of Health data, 2015-2019.

Queens County, Questions
Questions about radon in Queens County
Common questions8 questions, answered from the figures above
How do I get a radon test in Queens 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 Queens County as a service area yet. The New York radon program is the place to ask about certified testers and any test kit offer it runs.

Are radon levels high in Queens County?
In 2023, 9.1% of the radon tests reported to CDC for Queens County, New York were at or above 4 pCi/L, and the median reported pre-mitigation result was 0.5 pCi/L. That is a share of reported tests, not of homes. EPA places Queens County in Zone 3, lower predicted potential, a predicted average indoor screening level less than 2 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.
Who does radon mitigation in Queens County?
No listed mitigator names Queens County as a service area yet; the New York directory lists 12 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. Your state radon program is the place to check whether New York requires one.
How radon mitigation worksWhat mitigation costsMitigators in New York
What EPA radon zone is Queens County in?
EPA places Queens County, New York in Zone 3, which EPA describes as lower 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 Queens 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 Queens County?
Queens County borders 4 counties, derived from Census county geometry. Radon potential follows geology rather than county lines, so a bordering county's report can be relevant.

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.
