RL416 long-term radon test kit, lab fee included
- Lab fee included
Method: Alpha track
In home: 90 days to 12 months
Locations and reports
EPA puts Nottoway County in Zone 1, its highest radon zone, and only 8 radon tests from it are on file with CDC (2008 to 2017, laboratory totals). Homes with elevated levels occur in all three zones, so only a test measures yours.

Measured: tests reported to CDC
CDC holds 8 reported tests for Nottoway County over the 2008 to 2017 laboratory totals, with a median of 2.1 pCi/L: too few to describe a county (Radon411 reads a share from 30 tests up). Nottoway County beside the counties around it is how this page reads it.
Only 8 tests were reported to CDC for Nottoway 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.

Nottoway County, Compared
CDC's largest figure for Nottoway County rests on 18 tests over the 2007 to 2016 laboratory totals, 2 of them at or above 4 pCi/L, so each test moves its share by 5.6 points and no rank or comparison is drawn from it. Results reached as high as 6.7 pCi/L, with a middle value of 0.6 pCi/L.
Of the counties bordering it, 2 have a figure over the 2006 to 2015 laboratory totals: Prince Edward County reported the largest share at or above 4 pCi/L, 40.9%, and Brunswick County the smallest, 36.4%. Farther out, Chesterfield County (30 miles away) at 30.5%, Mecklenburg County (36 miles away) at 34.2% and Goochland County (41 miles away) at 31.3% 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 Nottoway County in Zone 1, the map's highest label: a predicted county average above 4 pCi/L. USGS geology rates 100% of the county's land high radon potential.

Nottoway County, Geology
USGS's geologic map puts all of Nottoway County's mapped land in one class: high radon potential. All of it lies in the area the map calls Goochland Terrane, to which USGS gives a radon index of 13, in the high band (12 to 17).
| Area | The rock, in USGS's words | Potential | Radon index | Share of land |
|---|---|---|---|---|
| Goochland Terrane | Granite, pegmatites, granitic gneiss, schist and gneiss, slate, and phyllite. | High | 13 | 100% |
