Radon tests reported for Fulton County, 2008 to 2017, laboratory
CDC holds 1 reported test for Fulton County over the 2008 to 2017 laboratory totals, a result of 1.9 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 1 test was 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 1 test over the 2008 to 2017 laboratory totals, 0 of them at or above 4 pCi/L, so each test moves its share by 100.0 points and no rank or comparison is drawn from it. Results reached as high as 1.9 pCi/L, with a middle value of 1.9 pCi/L.
Obion County, TN, the one bordering county with a figure over the 2008 to 2017 laboratory totals, reported 11.1% of its tests at or above 4 pCi/L. Farther out, Marshall County (53 miles away) at 10.6%, Trigg County (75 miles away) at 22.2% and Christian County (97 miles away) at 36.1% have figures too. Pooled across 120 Kentucky counties, 43.7% of reported tests reached that level; across every county in the country with a figure, 35.7%.
Statewide for the same period, Meade County reported the highest share (68.4%) and Hopkins County the lowest (9.5%). EPA's 1993 map puts Fulton County in Zone 3, its lowest label: a predicted county average under 2 pCi/L. USGS geology rates 100% of the county's land low radon potential.

Fulton County, Geology
The ground under Fulton County
PredictedUSGS's geologic map puts all of Fulton County's mapped land in one class: low radon potential. The map puts 50.1% of Fulton County in the area it calls Jackson Purchase and 48.3% in Coastal Plains Province, with one smaller area beside them. USGS gives the first a radon index of 6 and the second 5, both in the low band (5 to 8).
| Area | The rock, in USGS's words | Potential | Radon index | Share of land |
|---|---|---|---|---|
| Jackson Purchase | Cretaceous and Tertiary marine and continental gravels, sands, silts, and clays, overlain by alluvium and loess. | Low | 6 | 50.1% |
| Coastal Plains Province | Tertiary-Quaternary sandstone, shale, and alluvium. | Low | 5 | 48.3% |
| Loess-Covered Coastal Plain | Cretaceous and younger marine and fluvial sand, clay, and marl covered with loess. | Low | 8 | 1.2% |

Fulton County beside the ground around it
Across Kentucky 18.2% of the land is rated high; none of Fulton County's is. None of the 5 counties that border it has any moderate-potential ground either.
