Radon tests reported for Covington County, 2008 to 2017, laboratory
CDC holds 2 reported tests for Covington 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). Covington County beside the counties around it is how this page reads it.
What these figures count
Only 2 tests were reported to CDC for Covington 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).
Covington County, Compared
Covington County radon figures, compared
Calculated by Radon411CDC's largest figure for Covington 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 0.7 pCi/L, with a middle value of 0.6 pCi/L.
Okaloosa County, FL, the one bordering county with a figure over the 2008 to 2017 laboratory totals, reported 2.9% of its tests at or above 4 pCi/L. Farther out, Montgomery County (68 miles away) at 9.7%, Baldwin County (84 miles away) at 0.0% and Autauga County (89 miles away) at 17.1% have figures too. Pooled across 65 Alabama counties, 21.9% of reported tests reached that level; across every county in the country with a figure, 35.7%.
Statewide for the same period, Colbert County reported the highest share (36.2%) and Baldwin County the lowest (0.0%). EPA's 1993 map puts Covington 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.

|---|---|---|---|---|
| Coastal Plain | Marly sandy clay, chalk, and glauconitic sands. | Low | 7 | 99.9% |
