Radon tests reported for Greensville County, 2008 to 2017, laboratory
CDC holds 2 reported tests for Greensville County over the 2008 to 2017 laboratory totals, with a median of 0.7 pCi/L: too few to describe a county (Radon411 reads a share from 30 tests up). Greensville County beside the counties around it is how this page reads it.
What these figures count
Only 2 tests were reported to CDC for Greensville 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).
Greensville County, Compared
Greensville County radon figures, compared
Calculated by Radon411CDC's largest figure for Greensville County rests on 2 tests over the 2008 to 2017 laboratory totals, 0 of them at or above 4 pCi/L, so each test moves its share by 50.0 points and no rank or comparison is drawn from it. Results reached as high as 0.7 pCi/L, with a middle value of 0.7 pCi/L.
Of the counties bordering it, 2 have a figure over the 2006 to 2015 laboratory totals: Northampton County, NC reported the largest share at or above 4 pCi/L, 37.0%, and Brunswick County the smallest, 36.4%. Farther out, Mecklenburg County (45 miles away) at 34.2%, Chesterfield County (48 miles away) at 30.5% and Richmond city (59 miles away) at 28.0% have figures too. 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 Greensville 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.

The ground under Greensville County
PredictedMost of the ground under Greensville County is one class on USGS's geologic map: 99.5% of its land is low radon potential, with 0.5% high. The map puts 80.8% of Greensville County in the area it calls Tertiary Coastal Plain Sediments and 18.3% in Eastern Slate Belt. USGS gives both 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 | 80.8% |
| Eastern Slate Belt | Proterozoic to Cambrian metamudstone and argillite, interbedded with metamorphosed sandstone, conglomerate, and volcanic rock. | Low | 8 | 18.3% |

Greensville County, Cities and towns
Cities and towns in Greensville County
About 11,181 people live in Greensville County by the Census Bureau's estimate for July 1, 2025, 206 fewer than in 2020 (−1.8%). That works out to 38 people per square mile of land. Jarratt, the largest place on its list (646 residents in all), extends beyond Greensville County, so no share of the total is worked out for it. Reported testing is thin here: 2 tests over 2008 to 2017, or 0.2 for every 1,000 residents (2025 estimate), where Virginia as a whole comes to 6.0.
Jarratt is the one incorporated place here; CDC publishes no figure by town, so it reads Greensville County's.
