2020: 67.9%. Across these years the share ran from 57.1% to 78.6%. Each column counts radon tests reported to CDC that year, not homes.
What these figures count
Only 28 tests were reported to CDC for Fulton County over 2020, 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: 2020. Measured data period: 2005 to 2020 (every CDC figure on file).
Fulton County, Compared
Fulton County radon figures, compared
Calculated by Radon411More than half: 71.5% of the 137 radon tests reported to CDC for Fulton County over the 2007 to 2016 laboratory totals read at least 4 pCi/L. That places it 1st of 67 Pennsylvania counties with 30 or more tests for the same period. That is 28.5 points above the 43.0% pooled from 67 Pennsylvania counties.
The newest figure, in 2020, counts only 28 tests (67.9% at or above 4 pCi/L), too few to compare, so this reading uses the 137-test figure.
The median result, 8.6 pCi/L, sits above EPA's 4 pCi/L action level, and the top reported result was 114.2 pCi/L. The rest split 17.5% under 2 pCi/L and 10.9% from 2 to 4 (Pennsylvania: 34.3% and 22.7%). Zone 1 on EPA's map (predicted average above 4 pCi/L) and a 71.5% share point the same way here.
No bordering county with a figure for the same period reported a higher share; the closest is Franklin County at 64.5%, the lowest Allegany County, MD at 35.4%. Statewide for the same period, Centre County reported the highest share (67.9%) and Philadelphia County the lowest (13.3%).
The busiest year on file was 2014, with 44 tests reported; the quietest, 2017, had 21.
Over 3 years of annual figures the share fell 8.5 points, from 77.3% in 2014 to 68.8% in 2019; its peak was 77.3% in 2014. Nationally, every county with a figure for the same period pools to 35.8%; Fulton County sits 35.7 points above it. CDC also counts 10 tests taken after mitigation in Fulton County for the same period: tests in homes where a fix was already in.

Fulton County, Geology
The ground under Fulton County
PredictedUSGS's geologic map puts all of Fulton County's mapped land in one class: high radon potential. All of it lies in the area the map calls Appalachian Mountain Section, 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 |
|---|---|---|---|---|
| Appalachian Mountain Section | Paleozoic sandstone, shale, and limestone. | High | 12 | 99.8% |
