Surry County, Compared
Surry County radon figures, compared
Calculated by Radon411CDC's county radon counts over the 2006 to 2015 laboratory totals cover 132 Virginia counties, and Surry County is not among them: no year's figure and no ten-year laboratory total names it. Pooled across 132 Virginia counties, 30.7% of reported tests reached that level; across every county in the country with a figure, 36.3%.
The nearest counties with a figure are James City County (17 miles away) at 38.4%, Newport News city (21 miles away) at 5.9% and Norfolk city (38 miles away) at 5.3%. 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 Surry County in Zone 3, its lowest label: a predicted county average under 2 pCi/L. USGS geology rates 99% of the county's land low radon potential.
