Predicted: EPA radon zone

EPA Zone 1: highest predicted potential

EPA puts all of Pittsylvania County in and predicts an average indoor of greater than 4 pCi/L (greater than 150 Bq/m³) across the county. That is one forecast for the whole county, not a reading of any address in it; homes above EPA's turn up in all three zones.

Pittsylvania County, Compared

Pittsylvania County radon figures, compared

Calculated by Radon411

In Pittsylvania County, about 4 in 10 reported tests over the 2008 to 2017 laboratory totals (93 of 242) were at or above EPA's action level. Against the national pool of 35.7%, the gap is 2.7 points higher. Across 131 Virginia counties pooled together, 30.4% of tests reached that level, so Pittsylvania County runs 8.0 points above its state.

Of 8 neighbours with a figure, 1 reported a larger share at or above 4 pCi/L and 7 a smaller one; the spread is 14.9% (Caswell County, NC) to 39.7% (Campbell County). By share, Pittsylvania County is 32nd of 84 Virginia counties with 30 or more tests for the same period.

Half the tests came in under 3.0 pCi/L and half over it; the single highest reached 28.2 pCi/L. Below the action level, 82 tests (33.9%) came in under 2 pCi/L, against 44.7% statewide, and 67 tests (27.7%) fell between 2 and 4, against 24.9% statewide.

Zone 1 on EPA's map (predicted average above 4 pCi/L) and a 38.4% share point the same way here. USGS geology rates 52% of the county's land high radon potential. CDC also counts 20 tests taken after mitigation in Pittsylvania County for the same period: tests in homes where a fix was already in.

CDC's ten-year totals for Pittsylvania County went from 221 tests (2005 to 2014) to 242 (2008 to 2017), the share going from 41.6% to 38.4%.

The ground under Pittsylvania County

Predicted

USGS's geologic map splits Pittsylvania County: 52.3% of its land is high radon potential and 47.7% moderate. The map puts 52.3% of Pittsylvania County in the area it calls Inner Piedmont and 27.7% 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).
