Radon tests reported for Charlotte County, 2008 to 2017, laboratory
CDC holds 20 reported tests for Charlotte County over the 2008 to 2017 laboratory totals, with a median of 3.7 pCi/L: too few to describe a county (Radon411 reads a share from 30 tests up). Charlotte County beside the counties around it is how this page reads it.
What these figures count
Only 20 tests were reported to CDC for Charlotte 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).
Charlotte County, Compared
Charlotte County radon figures, compared
Calculated by Radon411CDC's largest figure for Charlotte County rests on 20 tests over the 2008 to 2017 laboratory totals, 8 of them at or above 4 pCi/L, so each test moves its share by 5.0 points and no rank or comparison is drawn from it. Results reached as high as 8.7 pCi/L, with a middle value of 3.7 pCi/L.
Of the counties bordering it, 4 have a figure over the 2006 to 2015 laboratory totals: Prince Edward County reported the largest share at or above 4 pCi/L, 40.9%, and Appomattox County the smallest, 16.7%, with Campbell County at 39.1% and Mecklenburg County at 34.2% between. Farther out, Lynchburg city (40 miles away) at 28.0%, Pittsylvania County (43 miles away) at 40.0% and Brunswick County (48 miles away) at 36.4% have figures too. Pooled across 132 Virginia counties, 30.7% of reported tests reached that level; across every county in the country with a figure, 36.3%.
Statewide for the same period, Russell County reported the highest share (68.5%) and Norfolk city the lowest (5.3%). EPA's 1993 map puts Charlotte 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.

The ground under Charlotte County
PredictedUSGS's geologic map puts all of Charlotte County's mapped land in one class: moderate radon potential. The map puts 93.1% of Charlotte County in the area it calls Carolina Terrane and 6.9% in Mesozoic Basins. USGS gives the first a radon index of 10 and the second 11, both in the moderate band (9 to 11).
| Area | The rock, in USGS's words | Potential | Radon index | Share of land |
|---|---|---|---|---|
| Carolina Terrane | Metavolcanic rocks, granite and granitic gneiss. | Moderate | 10 | 93.1% |
| Mesozoic Basins | Sandstone, siltstone and lacustrine black shale. | Moderate | 11 | 6.9% |
