- Lab fee included
Method: Liquid scintillation
In home: 48 to 96 hours
Locations and reports
EPA puts Haywood County in Zone 2, its middle radon zone, and only 18 radon tests from it are on file with CDC (2022). Homes with elevated levels occur in all three zones, so only a test measures yours.

2022: 5.6%. Across these years the share ran from 5.6% to 23.1%. Each column counts radon tests reported to CDC that year, not homes.
Only 18 tests were reported to CDC for Haywood County over 2022, 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: 2022. Measured data period: 2005 to 2022 (every CDC figure on file).
Haywood County, Compared
In Haywood County, about 3 in 10 reported tests over the 2007 to 2016 laboratory totals (590 of 1,951) were at or above EPA's action level. Against the national pool of 35.8%, the gap is 5.6 points lower. Across 99 North Carolina counties pooled together, 23.2% of tests reached that level, so Haywood County runs 7.0 points above its state.
The newest figure, in 2022, counts only 18 tests (5.6% at or above 4 pCi/L), too few to compare, so this reading uses the 1,951-test figure.
Of 8 neighbours with a figure, 6 reported a larger share at or above 4 pCi/L and 2 a smaller one; the spread is 14.8% (Madison County) to 52.3% (Sevier County, TN). By share, Haywood County is 21st of 73 North Carolina counties with 30 or more tests for the same period.
Year by year, 2014 opened at 23.0% and 2021 closed at 23.1% (about level), with 2021 the high at 23.1%. Half the tests came in under 2.2 pCi/L and half over it; the single highest reached 108.1 pCi/L. Below the action level, 891 tests (45.7%) came in under 2 pCi/L, against 55.2% statewide, and 470 tests (24.1%) fell between 2 and 4, against 21.6% statewide.
Zone 2 on EPA's map (predicted average between 2 and 4 pCi/L) and a 30.2% share point the same way here. USGS geology rates 100% of the county's land moderate radon potential. CDC also counts 20 tests taken after mitigation in Haywood County for the same period: tests in homes where a fix was already in.
The busiest year on file was 2020, with 296 tests reported; the quietest, 2022, had 18.
| Year | Tests | Haywood County, at or above 4 pCi/L | North Carolina, pooled |
|---|---|---|---|
| 2014 | 274 | 23.0% | 21.9% |
| 2020 | 296 | 23.0% | 21.1% |

Haywood County, Geology
USGS's geologic map puts all of Haywood County's mapped land in one class: moderate radon potential. The map puts 87.6% of Haywood County in the area it calls Blue Ridge and 12.4% in Georgiabama Thrust Stack (South). USGS gives the first a radon index of 10 and the second 9, both in the moderate band (9 to 11).
| Area | The rock, in USGS's words | Potential | Radon index | Share of land |
|---|---|---|---|---|
| Blue Ridge | Granite, pegmatite, monazite, schist, and gneiss. | Moderate | 10 | 87.6% |
| Georgiabama Thrust Stack (South) | Schist, amphibolite and granite. | Moderate | 9 | 12.4% |
