Radon tests reported for Sussex County, 2008 to 2017, laboratory
CDC holds 1 reported test for Sussex County over the 2008 to 2017 laboratory totals, a result of 0.1 pCi/L: too few to describe a county (Radon411 reads a share from 30 tests up). Sussex County beside the counties around it is how this page reads it.
What these figures count
Only 1 test was reported to CDC for Sussex County over 2008 to 2017 (laboratory totals), 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: 2008 to 2017, laboratory. Measured data period: 2005 to 2017 (every CDC figure on file).
Sussex County, Compared
Sussex County radon figures, compared
Calculated by Radon411CDC's largest figure for Sussex County rests on 1 test over the 2008 to 2017 laboratory totals, 0 of them at or above 4 pCi/L, so each test moves its share by 100.0 points and no rank or comparison is drawn from it. Results reached as high as 0.1 pCi/L, with a middle value of 0.1 pCi/L.
The nearest counties with a figure are Brunswick County (35 miles away) at 36.4%, Chesterfield County (36 miles away) at 30.5% and James City County (39 miles away) at 38.4%. Pooled across 132 Virginia counties, 30.7% of reported tests reached that level; across every county in the country with a figure, 36.3%.
Statewide for the same period, Russell County reported the highest share (68.5%) and Norfolk city the lowest (5.3%). EPA's 1993 map puts Sussex 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.

Sussex County, Geology
The ground under Sussex County
PredictedUSGS's geologic map puts all of Sussex County's mapped land in one class: low radon potential. All of it lies in the area the map calls Tertiary Coastal Plain Sediments, 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 |
|---|---|---|---|---|
| Tertiary Coastal Plain Sediments | Tertiary Coastal Plain sand, silt, clay | Low | 8 | 100% |

Sussex County beside the ground around it
Across Virginia 47.9% of the land is rated high; none of Sussex County's is. Of the 5 counties that border it, 2 have more high-potential ground, Dinwiddie County the most at 67.4%.
The map rates the ground, not the air in any home.

Sussex County, Cities and towns
Cities and towns in Sussex County
Sussex County's population has barely moved since 2020: 10,755 residents on July 1, 2025 against 10,799 then, by the Census Bureau's estimates. That works out to 22 people per square mile of land. No town dominates: Waverly, the largest, has 1,936 residents, 18.0% of the total. Reported testing is thin here: 1 test over 2008 to 2017, or 0.1 for every 1,000 residents (2025 estimate), where Virginia as a whole comes to 6.0.
From Waverly to Stony Creek, CDC publishes no figure by town: each reads Sussex County's.
| Place | Residents | Since 2020 | Share of residents |
|---|---|---|---|
| Waverly | 1,936 | −0.5% | 18.0% |
| Wakefield | 746 | −0.8% | 6.9% |
| Jarrattextends beyond Sussex County | 646 | −2.6% | Counted whole |
| Stony Creek | 201 | −1.0% | 1.9% |
4 incorporated places, as listed in the U.S. Census Bureau’s 2020 place reference files. Residents: U.S. Census Bureau population estimates for July 1, 2025 (Vintage 2025). A place that extends beyond Sussex County is counted whole, so it has no share.
