Patrick County, At a glance

Predicted: EPA radon zone

EPA Zone 1: highest predicted potential

EPA puts all of Patrick 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.

Patrick County, Compared

Patrick County radon figures, compared

Calculated by Radon411

More than half: 54.7% of the 53 radon tests reported to CDC for Patrick County over the 2008 to 2017 laboratory totals read at least 4 pCi/L. That places it 7th of 84 Virginia counties with 30 or more tests for the same period. That is 24.3 points above the 30.4% pooled from 131 Virginia counties.

The median result, 5.3 pCi/L, sits above EPA's 4 pCi/L action level, and the top reported result was 35.0 pCi/L. The rest split 26.4% under 2 pCi/L and 18.9% from 2 to 4 (Virginia: 44.7% and 24.9%). Zone 1 on EPA's map (predicted average above 4 pCi/L) and a 54.7% share point the same way here.

1 of its 6 bordering counties with figures ran higher, led by Carroll County at 61.8%; Franklin County reported 21.2%. Statewide for the same period, Russell County reported the highest share (67.3%) and Norfolk city the lowest (2.7%).

CDC's ten-year totals for Patrick County went from 55 tests (2005 to 2014) to 53 (2008 to 2017), the share going from 50.9% to 54.7%.

Nationally, every county with a figure for the same period pools to 35.7%; Patrick County sits 19.0 points above it.

Patrick County, Geology

The ground under Patrick County

Predicted

USGS's geologic map splits Patrick County: 55.7% of its land is moderate radon potential and 44.3% high. The map puts 55.7% of Patrick County in the area it calls Blue Ridge and 44.3% in Inner Piedmont. USGS gives the first a radon index of 10, in the moderate band (9 to 11), and the second 12, in the high band (12 to 17).
