Measured: tests reported to CDC
CDC holds 12 reported tests for Bath County over the 2008 to 2017 laboratory totals, with a median of 3.1 pCi/L: too few to describe a county (Radon411 reads a share from 30 tests up). Bath County beside the counties around it is how this page reads it.
Only 12 tests were reported to CDC for Bath 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).
Bath County, Compared
CDC's largest figure for Bath County rests on 12 tests over the 2008 to 2017 laboratory totals, 5 of them at or above 4 pCi/L, so each test moves its share by 8.3 points and no rank or comparison is drawn from it. Results reached as high as 16.7 pCi/L, with a middle value of 3.1 pCi/L.
Of the counties bordering it, 4 have a figure over the 2008 to 2017 laboratory totals: Bourbon County reported the largest share at or above 4 pCi/L, 53.5%, and Rowan County the smallest, 18.9%, with Montgomery County at 51.4% and Menifee County at 22.0% between. Farther out, Clark County (25 miles away) at 29.0%, Mason County (31 miles away) at 25.0% and Estill County (33 miles away) at 44.1% 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 Bath County in Zone 2, its middle label: a predicted county average between 2 and 4 pCi/L. USGS geology rates 65% of the county's land moderate radon potential.

Bath County, Geology
USGS's geologic map splits Bath County: 64.6% of its land is moderate radon potential and 35.4% high. The map puts 45.8% of Bath County in the area it calls Outer Bluegrass and 35.4% in New Albany-Chattanooga Shale, with one smaller area beside them. USGS gives the first a radon index of 11, in the moderate band (9 to 11), and the second 14, in the high band (12 to 17).
| Area | The rock, in USGS's words | Potential | Radon index | Share of land |
|---|---|---|---|---|
| Outer Bluegrass | Ordovician-Devonian limestone and shale. | Moderate | 11 | 45.8% |
| New Albany-Chattanooga Shale | Devonian/Mississippian Black shale. | High | 14 | 35.4% |
| Mississippian Plateau | Mississippian marine limestones, dolomites, marine sandstones, siltstones, and shales. | Moderate | 11 | 18.9% |
