Predicted: EPA radon zone

EPA Zone 3: lower predicted potential

is EPA's lowest class, and its forecast for Pasquotank 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 Pasquotank County, 2014

CDC holds 1 reported test for Pasquotank County in 2014, a result of 0.1 pCi/L: too few to describe a county (Radon411 reads a share from 30 tests up). Pasquotank County beside the counties around it is how this page reads it.

What these figures count

Only 1 test was reported to CDC for Pasquotank County over 2014, 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: 2014. Measured data period: 2005 to 2017 (every CDC figure on file).

Pasquotank County, Compared

Pasquotank County radon figures, compared

Calculated by Radon411

CDC's largest figure for Pasquotank County rests on 8 tests over the 2008 to 2017 laboratory totals, 3 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 7.5 pCi/L, with a middle value of 0.6 pCi/L.

The nearest counties with a figure are Dare County (45 miles away) at 26.8%, Northampton County (63 miles away) at 40.3% and Halifax County (76 miles away) at 42.4%. 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 Pasquotank County in Zone 3, its lowest label: a predicted county average under 2 pCi/L. USGS geology rates 97% of the county's land low radon potential.

Pasquotank County, Cities and towns

Cities and towns in Pasquotank County

The Census Bureau estimates 42,201 residents in Pasquotank County for July 1, 2025, 1,801 more than in 2020 (+4.5%). That works out to 186 people per square mile of land. Elizabeth City, the largest place on its list (19,622 residents in all), extends beyond Pasquotank County, so no share of the total is worked out for it.
