What these figures count
Only 15 tests were reported to CDC for Kings 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.
Measured: CDC tracking data. Figure above: 2023. Measured data period: 2005 to 2023 (every CDC figure on file).
Kings County, Compared
Kings County radon figures, compared
Calculated by Radon411Kings County reports fewer high tests than New York overall. 8.1% of its 707 tests over the 2008 to 2017 laboratory totals were at or above 4 pCi/L. That is 16.4 points below the 24.5% pooled from 62 New York counties.
The newest figure, in 2023, counts only 15 tests (0.0% at or above 4 pCi/L), too few to compare, so this reading uses the 707-test figure.
Ordered from highest share down, it comes 55th 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%; Kings County sits 27.6 points below it.
Next door, the shares run from 5.3% in Queens County to 7.1% in New York County, with New York County and Queens County below Kings County. Zone 3 on EPA's map (predicted average under 2 pCi/L) and a 8.1% share point the same way here.
Half the tests came in under 0.7 pCi/L and half over it; the single highest reached 31.0 pCi/L. The rest split 80.5% under 2 pCi/L and 11.5% from 2 to 4 (New York: 51.7% and 23.7%).
The busiest year on file was 2016, with 23 tests reported; the quietest, 2022, had 3.

Tests behind these figures
12.8 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.

Kings County, Cities and towns
Cities and towns in Kings County
About 2,653,963 people live in Kings County by the Census Bureau's estimate for July 1, 2025, 68,296 fewer than in 2020 (−2.5%). Packed into its land, that is 38,254 people per square mile. New York, the largest place on its list (8,584,629 residents in all), extends beyond Kings County, so no share of the total is worked out for it. Reported testing is thin here: 707 tests over 2008 to 2017, or 0.3 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 Kings County's.
