Radon tests reported for Ballard County, 2008 to 2017, laboratory
CDC holds 4 reported tests for Ballard County over the 2008 to 2017 laboratory totals, with a median of 1.4 pCi/L: too few to describe a county (Radon411 reads a share from 30 tests up). Ballard County beside the counties around it is how this page reads it.
What these figures count
Only 4 tests were reported to CDC for Ballard 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).
Ballard County, Compared
Ballard County radon figures, compared
Calculated by Radon411CDC's largest figure for Ballard County rests on 5 tests over the 2006 to 2015 laboratory totals, 0 of them at or above 4 pCi/L, so each test moves its share by 20.0 points and no rank or comparison is drawn from it. Results reached as high as 3.0 pCi/L, with a middle value of 1.8 pCi/L.
The nearest counties with a figure are Marshall County (39 miles away) at 10.6%, Trigg County (65 miles away) at 22.2% and Hopkins County (82 miles away) at 9.5%. 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 Ballard 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.

Ballard County, Geology
The ground under Ballard County
PredictedUSGS's geologic map puts all of Ballard County's mapped land in one class: low radon potential. The map puts 84.4% of Ballard County in the area it calls Jackson Purchase and 15.5% in Coastal Plains Province. 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 | 84.4% |
| Coastal Plains Province | Tertiary-Quaternary sandstone, shale, and alluvium. | Low | 5 | 15.5% |
