2023: 9.1%. Across these years the share ran from 0.0% to 33.3%. Each column counts radon tests reported to CDC that year, not homes.
Only 11 tests were reported to CDC for Queens County over 2023, and tests are often run on homes being sold or already suspected of a problem: so few describe neither the county nor this house.

Queens County, Compared
Queens County reports fewer high tests than New York overall. 5.3% of its 419 tests over the 2008 to 2017 laboratory totals were at or above 4 pCi/L. That is 19.2 points below the 24.5% pooled from 62 New York counties.
The newest figure, in 2023, counts only 11 tests (9.1% at or above 4 pCi/L), too few to compare, so this reading uses the 419-test figure.
Ordered from highest share down, it comes 59th of 61 New York counties with 30 or more tests for the same period. Nationally, every county with a figure for the same period pools to 35.7%; Queens County sits 30.4 points below it.
Next door, the shares run from 3.2% in Bronx County to 8.1% in Kings County, with Nassau County and Bronx County below Queens County. Zone 3 on EPA's map (predicted average under 2 pCi/L) and a 5.3% share point the same way here.
Half the tests came in under 0.8 pCi/L and half over it; the single highest reached 135.6 pCi/L. The rest split 82.6% under 2 pCi/L and 12.2% from 2 to 4 (New York: 51.7% and 23.7%).
The busiest year on file was 2017, with 14 tests reported; the quietest, 2021, had 3.

Queens County, Geology
USGS's geologic map puts all of Queens County's mapped land in one class: low radon potential. 85.6% of it lies in the area the map calls Atlantic Coastal Plain, to which USGS gives a radon index of 7, in the low band (5 to 8).
| Area | The rock, in USGS's words | Potential | Radon index | Share of land |
|---|---|---|---|---|
| Atlantic Coastal Plain | Glacial deposits and marine sediments. | Low | 7 | 85.6% |

Across New York 48.9% of the land is rated high; none of Queens County's is. Of the 4 counties that border it, 2 have more moderate-potential ground, New York County the most at 84.1%.

Queens County, Cities and towns
About 2,358,182 people live in Queens County by the Census Bureau's estimate for July 1, 2025, 27,359 fewer than in 2020 (−1.1%). Packed into its land, that is 21,690 people per square mile. New York, the largest place on its list (8,584,629 residents in all), extends beyond Queens County, so no share of the total is worked out for it. Reported testing is thin here: 419 tests over 2008 to 2017, or 0.2 for every 1,000 residents (2025 estimate), where New York as a whole comes to 4.9.
New York is the one incorporated place here; CDC publishes no figure by town, so it reads Queens County's.

One incorporated place, as listed in the U.S. Census Bureau’s 2020 place reference files. Residents: U.S. Census Bureau population estimates for July 1, 2025 (Vintage 2025). A place that extends beyond Queens County is counted whole, so it has no share.
