Radon tests reported for Braxton County, 2008 to 2017, laboratory
CDC holds 12 reported tests for Braxton 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). Braxton County beside the counties around it is how this page reads it.
What these figures count
Only 12 tests were reported to CDC for Braxton 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).
Braxton County, Compared
Braxton County radon figures, compared
Calculated by Radon411CDC's largest figure for Braxton County rests on 12 tests over the 2008 to 2017 laboratory totals, 3 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 4.2 pCi/L, with a middle value of 1.3 pCi/L.
The nearest counties with a figure are Harrison County (44 miles away) at 36.4%, Randolph County (46 miles away) at 36.4% and Kanawha County (50 miles away) at 20.6%. Pooled across 55 West Virginia counties, 37.5% of reported tests reached that level; across every county in the country with a figure, 35.7%.
Statewide for the same period, Morgan County reported the highest share (58.1%) and Grant County the lowest (9.8%). EPA's 1993 map puts Braxton County in Zone 2, its middle label: a predicted county average between 2 and 4 pCi/L. USGS geology rates 100% of the county's land moderate radon potential.

Braxton County, Geology
The ground under Braxton County
PredictedUSGS's geologic map puts all of Braxton County's mapped land in one class: moderate radon potential. 96.4% of it lies in the area the map calls Central Allegheny Plateau, to which USGS gives a radon index of 10, in the moderate band (9 to 11).
| Area | The rock, in USGS's words | Potential | Radon index | Share of land |
|---|---|---|---|---|
| Central Allegheny Plateau | Permian and Pennsylvanian shale, siltstone, sandstone, minor limestone. | Moderate | 10 | 96.4% |
| Eastern Allegheny Plateau and Mtns | Devonian-Pennsylvanian shale, siltstone, sandstone, minor limestone and coal | Moderate | 10 | 3.6% |

Braxton County beside the ground around it
Across West Virginia 18.7% of the land is rated high; none of Braxton County's is. Of the 6 counties that border it, none has as large a share of moderate-potential ground; Calhoun County comes nearest at 100%.
