Locations and reports
EPA puts Beaufort County in Zone 3, its lowest radon zone, and only 6 radon tests from it are on file with CDC (2020). Homes with elevated levels occur in all three zones, so only a test measures yours.

| Year | Share of reported tests at or above 4 pCi/L |
|---|---|
| 2014 | 0.0% |
| 2020 | 0.0% |
2020: 0.0%. Across these years the share ran from 0.0% to 0.0%. Each column counts radon tests reported to CDC that year, not homes.
Only 6 tests were reported to CDC for Beaufort 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).
Beaufort County, Compared
CDC's largest figure for Beaufort County rests on 26 tests over the 2007 to 2016 laboratory totals, 0 of them at or above 4 pCi/L, so each test moves its share by 3.8 points and no rank or comparison is drawn from it. Results reached as high as 2.6 pCi/L, with a middle value of 0.1 pCi/L.
Of the counties bordering it, 2 have a figure over the 2008 to 2017 laboratory totals: Pitt County reported the largest share at or above 4 pCi/L, 1.0%, and Craven County the smallest, 0.0%. Farther out, Carteret County (47 miles away) at 0.0%, Onslow County (62 miles away) at 2.7% and Dare County (63 miles away) at 26.8% 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 Beaufort County in Zone 3, its lowest label: a predicted county average under 2 pCi/L. USGS geology rates 96% of the county's land low radon potential.

Beaufort County, Geology
USGS's geologic map puts all of Beaufort County's mapped land in one class: low radon potential. The map puts 51.9% of Beaufort County in the area it calls Outer Coastal Plain and 44.2% in Inner Coastal Plain. USGS gives the first a radon index of 7 and the second 8, both in the low band (5 to 8).
| Area | The rock, in USGS's words | Potential | Radon index | Share of land |
|---|---|---|---|---|
| Outer Coastal Plain | Unconsolidated sand. | Low | 7 | 51.9% |
| Inner Coastal Plain | Fossiliferous clay and sand, shelly sand, sandy marl, and limestone. | Low | 8 | 44.2% |

Across North Carolina 1.3% of the land is rated high; none of Beaufort County's is. None of the 6 counties that border it has any moderate-potential ground either.

No CDC figure names Beaufort County; the nearest county with one, Craven County (29 miles away), reported 0.0% of its tests at or above 4 pCi/L over the 2008 to 2017 laboratory totals, the only reading nearby until a test of this home. Zone 3 is the lowest label, yet homes at or above 4 pCi/L occur in every zone: a short-term kit (2 to 90 days) is the quick first check in Beaufort County.

Beaufort County, Cities and towns
Beaufort County's population has barely moved since 2020: 44,670 residents on July 1, 2025 against 44,694 then, by the Census Bureau's estimates. That works out to 54 people per square mile of land. Its largest town, Washington, has 9,910 residents, 22.2% of the total. Together its 7 incorporated places hold 29.8% of those residents; the other 70.2% live outside any of them.

From Washington to Pantego, CDC publishes no figure by town: each reads Beaufort County's.
