Radon tests reported for Fulton County, 2008 to 2017, laboratory
CDC holds 2 reported tests for Fulton County over the 2008 to 2017 laboratory totals, with a median of 5.9 pCi/L: too few to describe a county (Radon411 reads a share from 30 tests up). Fulton County beside the counties around it is how this page reads it.
What these figures count
Only 2 tests were reported to CDC for Fulton County over 2008 to 2017 (laboratory totals), 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: 2008 to 2017, laboratory. Measured data period: 2005 to 2017 (every CDC figure on file).
Fulton County, Compared
Fulton County radon figures, compared
Calculated by Radon411CDC's largest figure for Fulton County rests on 4 tests over the 2005 to 2014 laboratory totals, 2 of them at or above 4 pCi/L, so each test moves its share by 25.0 points and no rank or comparison is drawn from it. Results reached as high as 13.6 pCi/L, with a middle value of 5.9 pCi/L.
Howell County, MO, the one bordering county with a figure over the 2007 to 2016 laboratory totals, reported 45.1% of its tests at or above 4 pCi/L. Farther out, Pulaski County (115 miles away) at 6.8%, Saline County (129 miles away) at 31.9% and Benton County (136 miles away) at 31.0% have figures too. Pooled across 60 Arkansas counties, 22.7% of reported tests reached that level; across every county in the country with a figure, 35.8%.
Statewide for the same period, Garland County reported the highest share (45.8%) and Pulaski County the lowest (6.8%). EPA's 1993 map puts Fulton County in Zone 2, its middle label: a predicted county average between 2 and 4 pCi/L. USGS geology rates 100% of the county's land moderate radon potential.
Pooled shares: Radon411's sum of CDC's county counts for one period.

The ground under Fulton County
PredictedUSGS's geologic map puts all of Fulton County's mapped land in one class: moderate radon potential. 99.5% of it lies in the area the map calls Salem Plateau, to which USGS gives a radon index of 9, in the moderate band (9 to 11).
| Area | The rock, in USGS's words | Potential | Radon index | Share of land |
|---|---|---|---|---|
| Salem Plateau | Ordovician dolomite. | Moderate | 9 | 99.5% |
| Salem Plateau | Ordovician dolomite, sandstone, limestone, and shale. | Moderate | 11 | 0.5% |

Fulton County, Cities and towns
Cities and towns in Fulton County
The Census Bureau estimates 12,492 residents in Fulton County for July 1, 2025, 440 more than in 2020 (+3.7%). That works out to 20 people per square mile of land. Cherokee Village, the largest place on its list (4,981 residents in all), extends beyond Fulton County, so no share of the total is worked out for it. Testing is reported here more often than across the state: CDC's 4 reported tests for 2005 to 2014 come to 0.3 for every 1,000 residents (2025 estimate), against 0.2 for Arkansas.
From Cherokee Village to Viola, CDC publishes no figure by town: each reads Fulton County's.
