What these figures count
Only 3 tests were reported to CDC for Schoharie 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).
Schoharie County, Compared
Schoharie County radon figures, compared
Calculated by Radon411Schoharie County's 504 reported tests over the 2008 to 2017 laboratory totals had a middle value of 1.7 pCi/L and a maximum of 52.1 pCi/L, and 21.8% reached 4 pCi/L. New York as a whole (62 New York counties, pooled) comes to 24.5%: 2.7 points higher than here.
The newest figure, in 2022, counts only 3 tests (0.0% at or above 4 pCi/L), too few to compare, so this reading uses the 504-test figure.
Among its state's counties it ranks 36th of 61 New York counties with 30 or more tests for the same period. Statewide for the same period, Chemung County reported the highest share (52.3%) and Bronx County the lowest (3.2%).
Below the action level, 275 tests (54.6%) came in under 2 pCi/L, against 51.7% statewide, and 119 tests (23.6%) fell between 2 and 4, against 23.7% statewide. The busiest year on file was 2017, with 39 tests reported; the quietest, 2022, had 3.
EPA's 1993 zone map puts Schoharie County in Zone 1, a predicted county average above 4 pCi/L. USGS geology rates 88% of the county's land high radon potential.
Next door, the shares run from 14.7% in Montgomery County to 37.6% in Otsego County, with Schenectady County, Albany County and Montgomery County below Schoharie County.
CDC also counts 10 tests taken after mitigation in Schoharie County for the same period: tests in homes where a fix was already in.
Pooled shares: Radon411's sum of CDC's county counts for one period.

Tests behind these figures
20.6 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.

USGS gives the first a radon index of 12, in the high band (12 to 17), and the second 11, in the moderate band (9 to 11).
| Area | The rock, in USGS's words | Potential | Radon index | Share of land |
|---|---|---|---|---|
| Allegheny Plateau | Shale, limestone, and sandstone. | High | 12 | 87.5% |
| Hudson-Mohawk Lowland | Sandstone, siltstone, shale, and conglomerates. | Moderate | 11 | 12.5% |
