Radon tests reported for Panola County, 2008 to 2017, laboratory
CDC holds 2 reported tests for Panola County over the 2008 to 2017 laboratory totals, with a median of 0.6 pCi/L: too few to describe a county (Radon411 reads a share from 30 tests up). Panola County beside the counties around it is how this page reads it.
What these figures count
Only 2 tests were reported to CDC for Panola 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: 2007 to 2017 (every CDC figure on file).
Panola County, Compared
Panola County radon figures, compared
Calculated by Radon411CDC's largest figure for Panola County rests on 2 tests over the 2008 to 2017 laboratory totals, 0 of them at or above 4 pCi/L, so each test moves its share by 50.0 points and no rank or comparison is drawn from it. Results reached as high as 0.6 pCi/L, with a middle value of 0.6 pCi/L.
The nearest counties with a figure are Smith County (58 miles away) at 9.1%, Montgomery County (147 miles away) at 7.1% and Collin County (150 miles away) at 7.7%. Pooled across 140 Texas counties, 10.4% of reported tests reached that level; across every county in the country with a figure, 35.8%.
Statewide for the same period, Randall County reported the highest share (71.4%) and Nueces County the lowest (0.0%). EPA's 1993 map puts Panola 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.

Panola County, Geology
The ground under Panola County
PredictedUSGS's geologic map puts all of Panola County's mapped land in one class: low radon potential. All of it lies in the area the map calls East Texas Province, to which USGS gives a radon index of 6, in the low band (5 to 8).
| Area | The rock, in USGS's words | Potential | Radon index | Share of land |
|---|---|---|---|---|
| East Texas Province | Cretaceous through Quaternary marine sandstone, shale, chalk, limestone, siltstone, clay, and lignite. | Low | 6 | 99.8% |

Panola County beside the ground around it
Across Texas 0.5% of the land is rated high; none of Panola County's is. None of the 5 counties that border it has any moderate-potential ground either.
