Measured: tests reported to CDC
CDC holds 11 reported tests for Livingston County over the 2008 to 2017 laboratory totals, with a median of 1.3 pCi/L: too few to describe a county (Radon411 reads a share from 30 tests up). Livingston County beside the counties around it is how this page reads it.
Only 11 tests were reported to CDC for Livingston 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.

Livingston County, Compared
CDC's largest figure for Livingston County rests on 18 tests over the 2005 to 2014 laboratory totals, 3 of them at or above 4 pCi/L, so each test moves its share by 5.6 points and no rank or comparison is drawn from it. Results reached as high as 6.1 pCi/L, with a middle value of 1.6 pCi/L.
Of the counties bordering it, 2 have a figure over the 2008 to 2017 laboratory totals: Massac County, IL reported the largest share at or above 4 pCi/L, 15.2%, and Marshall County the smallest, 10.6%. Farther out, Trigg County (38 miles away) at 22.2%, Hopkins County (45 miles away) at 9.5% and Christian County (52 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 Livingston County in Zone 2, its middle label: a predicted county average between 2 and 4 pCi/L. USGS geology rates 99% of the county's land moderate radon potential.

Livingston County, Geology
Most of the ground under Livingston County is one class on USGS's geologic map: 98.5% of its land is moderate radon potential, with 1.5% low. 97.5% of it lies in the area the map calls Mississippian Plateau, to which USGS gives a radon index of 11, in the moderate band (9 to 11).
| Area | The rock, in USGS's words | Potential | Radon index | Share of land |
|---|---|---|---|---|
| Mississippian Plateau | Mississippian marine limestones, dolomites, marine sandstones, siltstones, and shales. | Moderate | 11 | 97.5% |
| Jackson Purchase | Cretaceous and Tertiary marine and continental gravels, sands, silts, and clays, overlain by alluvium and loess. | Low | 6 | 1.4% |
| Shawnee Hills Section | Unglaciated Ordovician to Pennsylvanian limestone, sandstone, and shale. | Moderate | 10 | 1.0% |

Livingston County, Cities and towns
Livingston County's population has barely moved since 2020: 8,863 residents on July 1, 2025 against 8,871 then, by the Census Bureau's estimates. That works out to 28 people per square mile of land. No town dominates: Salem, the largest, has 704 residents, 7.9% of the total. Together its 4 incorporated places hold 15.1% of those residents; the other 84.9% live outside any of them. Reported testing is thin here: 18 tests over 2005 to 2014, or 2.0 for every 1,000 residents (2025 estimate), where Kentucky as a whole comes to 4.4.
From Salem to Carrsville, CDC publishes no figure by town: each reads Livingston County's.
