2022: 0.0%. Across these years the share ran from 0.0% to 100.0%. Each column counts radon tests reported to CDC that year, not homes.
What these figures count
Only 9 tests were reported to CDC for Yates County over 2022, 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: 2022. Measured data period: 2005 to 2022 (every CDC figure on file).
Yates County, Compared
Yates County radon figures, compared
Calculated by Radon411In Yates County, about 5 in 10 reported tests over the 2007 to 2016 laboratory totals (67 of 139) were at or above EPA's action level. Against the national pool of 35.8%, the gap is 12.4 points higher. Across 62 New York counties pooled together, 24.9% of tests reached that level, so Yates County runs 23.3 points above its state.
The newest figure, in 2022, counts only 9 tests (0.0% at or above 4 pCi/L), too few to compare, so this reading uses the 139-test figure.
Of 4 neighbours with a figure, none reported a larger share at or above 4 pCi/L; the spread is 21.1% (Seneca County) to 46.5% (Steuben County). By share, Yates County is 3rd of 61 New York counties with 30 or more tests for the same period.
Year by year, 2017 opened at 31.2% and 2020 closed at 25.0% (down 6.2 points), with 2017 the high at 31.2%. Half the tests came in under 3.6 pCi/L and half over it; the single highest reached 33.8 pCi/L. Below the action level, 42 tests (30.2%) came in under 2 pCi/L, against 51.6% statewide, and 30 tests (21.6%) fell between 2 and 4, against 23.5% statewide.
Zone 1 on EPA's map (predicted average above 4 pCi/L) and a 48.2% share point the same way here. USGS geology rates 100% of the county's land high radon potential. CDC also counts 6 tests taken after mitigation in Yates County for the same period: tests in homes where a fix was already in.
The busiest year on file was 2017, with 77 tests reported; the quietest, 2021, had 1.

Tests behind these figures
39.2 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.
Yates County, Geology
The ground under Yates County
PredictedUSGS's geologic map puts all of Yates County's mapped land in one class: high radon potential. All of it lies in the area the map calls Allegheny Plateau, to which USGS gives a radon index of 12, in the high band (12 to 17).
| Area | The rock, in USGS's words | Potential | Radon index | Share of land |
|---|---|---|---|---|
| Allegheny Plateau | Shale, limestone, and sandstone. | High | 12 | 100% |

Yates County beside the ground around it
Yates County has more high-potential ground than New York as a whole: 100% of its land against 48.9%. Of the 4 counties that border it, none has as large a share of high-potential ground; Schuyler County comes nearest at 100%.
