EPA Zone 3: lower predicted potential

is EPA's lowest class, and its forecast for Currituck County as a whole is an average indoor of less than 2 pCi/L (less than 75 Bq/m³). A low zone clears no address in it: homes above EPA's turn up in all three zones.

Measured: tests reported to CDC

Radon tests reported for Currituck County, 2020

CDC holds 4 reported tests for Currituck County in 2020, with a median of 1.1 pCi/L: too few to describe a county (Radon411 reads a share from 30 tests up). Currituck County beside the counties around it is how this page reads it.

What these figures count

Only 4 tests were reported to CDC for Currituck County over 2020, 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: 2020. Measured data period: 2005 to 2020 (every CDC figure on file).

Currituck County, Compared

Currituck County radon figures, compared

Calculated by Radon411

CDC's largest figure for Currituck County rests on 8 tests over the 2008 to 2017 laboratory totals, 0 of them at or above 4 pCi/L, so each test moves its share by 12.5 points and no rank or comparison is drawn from it. Results reached as high as 1.1 pCi/L, with a middle value of 0.3 pCi/L.

Of the counties bordering it, 3 have a figure over the 2008 to 2017 laboratory totals: Dare County reported the largest share at or above 4 pCi/L, 26.8%, and Virginia Beach city, VA the smallest, 4.3%, with Chesapeake city, VA at 7.0% between. Farther out, Northampton County (78 miles away) at 40.3%, Halifax County (92 miles away) at 42.4% and Pitt County (95 miles away) at 1.0% have figures too. Pooled across 99 North Carolina counties, 22.6% of reported tests reached that level; across every county in the country with a figure, 35.7%.

Statewide for the same period, Transylvania County reported the highest share (47.8%) and Nash County the lowest (0.0%). EPA's 1993 map puts Currituck County in Zone 3, its lowest label: a predicted county average under 2 pCi/L. USGS geology rates 87% of the county's land low radon potential.
