2021: 0.0%. Across these years the share ran from 0.0% to 14.3%. Each column counts radon tests reported to CDC that year, not homes.
Only 2 tests were reported to CDC for Edgecombe County over 2021, and tests are often run on homes being sold or already suspected of a problem: so few describe neither the county nor this house.

Edgecombe County, Compared
CDC's largest figure for Edgecombe County rests on 14 tests in 2014, 2 of them at or above 4 pCi/L, so each test moves its share by 7.1 points and no rank or comparison is drawn from it. Results reached as high as 5.4 pCi/L, with a middle value of 0.9 pCi/L.
Of the counties bordering it, 3 have a figure over the 2008 to 2017 laboratory totals: Halifax County reported the largest share at or above 4 pCi/L, 42.4%, and Nash County the smallest, 0.0%, with Pitt County at 1.0% between. Farther out, Northampton County (37 miles away) at 40.3%, Franklin County (40 miles away) at 19.1% and Warren County (44 miles away) at 42.7% 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 Edgecombe County in Zone 3, its lowest label: a predicted county average under 2 pCi/L. USGS geology rates 100% of the county's land low radon potential.
Pooled shares: Radon411's sum of CDC's county counts for one period.
Edgecombe County, Geology
USGS's geologic map puts all of Edgecombe County's mapped land in one class: low radon potential. All of it lies in the area the map calls Inner Coastal Plain, to which USGS gives a radon index of 8, in the low band (5 to 8).
| Area | The rock, in USGS's words | Potential | Radon index | Share of land |
|---|---|---|---|---|
| Inner Coastal Plain | Fossiliferous clay and sand, shelly sand, sandy marl, and limestone. | Low | 8 | 100% |
Names, descriptions and indexes: U.S. Geological Survey, Geologic Radon Potential Map (2025). Shares: Radon411, from the map cut to the boundary.
Across North Carolina 1.3% of the land is rated high; none of Edgecombe County's is. Of the 5 counties that border it, 2 have more moderate-potential ground, Nash County the most at 13.2%.
The map rates the ground, not the air in any home.
