Appomattox County, Compared
Appomattox County radon figures, compared
Calculated by Radon411Appomattox County reports fewer high tests than Virginia overall. 10.0% of its 50 tests over the 2008 to 2017 laboratory totals were at or above 4 pCi/L. That is 20.4 points below the 30.4% pooled from 131 Virginia counties.
Ordered from highest share down, it comes 79th of 84 Virginia counties with 30 or more tests for the same period. Nationally, every county with a figure for the same period pools to 35.7%; Appomattox County sits 25.7 points below it.
Next door, the shares run from 28.7% in Nelson County to 40.0% in Prince Edward County. The reported tests do not follow EPA's Zone 1 label for Appomattox County (predicted average above 4 pCi/L): 10.0% of them reached 4 pCi/L, fewer than that label suggests.
Half the tests came in under 2.1 pCi/L and half over it; the single highest reached 10.0 pCi/L. The rest split 44.0% under 2 pCi/L and 46.0% from 2 to 4 (Virginia: 44.7% and 24.9%).
CDC's ten-year totals for Appomattox County went from 37 tests (2005 to 2014) to 50 (2008 to 2017), the share going from 16.2% to 10.0%.

The ground under Appomattox County
PredictedUSGS's geologic map splits Appomattox County: 51.1% of its land is high radon potential and 48.9% moderate. The map puts 51.1% of Appomattox County in the area it calls Inner Piedmont and 48.3% in Carolina Terrane, with one smaller area beside them. USGS gives the first a radon index of 12, in the high band (12 to 17), and the second 10, in the moderate band (9 to 11).
| Area | The rock, in USGS's words | Potential | Radon index | Share of land |
|---|---|---|---|---|
| Inner Piedmont | Granite, pegmatites, granitic gneiss, schist and gneiss, slate, and phyllite. | High | 12 | 51.1% |
| Carolina Terrane | Metavolcanic rocks, granite and granitic gneiss. | Moderate | 10 | 48.3% |
| Mesozoic Basins | Sandstone, siltstone and lacustrine black shale. | Moderate | 11 | 0.6% |
