2023: 25.0%. Across these years the share ran from 11.1% to 100.0%. Each column counts radon tests reported to CDC that year, not homes.
Only 16 tests were reported to CDC for Oneida 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.

Oneida County, Compared
In Oneida County, about 3 in 10 reported tests over the 2008 to 2017 laboratory totals (709 of 2,051) were at or above EPA's action level. Against the national pool of 35.7%, the gap is 1.1 points lower. Across 62 New York counties pooled together, 24.5% of tests reached that level, so Oneida County runs 10.1 points above its state.
The newest figure, in 2023, counts only 16 tests (25.0% at or above 4 pCi/L), too few to compare, so this reading uses the 2,051-test figure.
Of 5 neighbours with a figure, 2 reported a larger share at or above 4 pCi/L and 2 a smaller one; the spread is 15.2% (Oswego County) to 41.5% (Herkimer County). By share, Oneida County is 18th of 61 New York counties with 30 or more tests for the same period.
Year by year, 2014 opened at 59.3% and 2020 closed at 57.1% (down 2.2 points), with 2015 the high at 65.7%. Half the tests came in under 2.5 pCi/L and half over it; the single highest reached 89.9 pCi/L. Below the action level, 854 tests (41.6%) came in under 2 pCi/L, against 51.7% statewide, and 488 tests (23.8%) fell between 2 and 4, against 23.7% statewide.
Zone 2 on EPA's map (predicted average between 2 and 4 pCi/L) and a 34.6% share point the same way here. USGS geology rates 81% of the county's land moderate radon potential. CDC also counts 71 tests taken after mitigation in Oneida County for the same period: tests in homes where a fix was already in.
The busiest year on file was 2017, with 56 tests reported; the quietest, 2021, had 1.
