- Lab fee included
Method: Liquid scintillation
In home: 48 to 96 hours
Locations and reports
EPA puts Lunenburg County in Zone 2, its middle radon zone, and only 4 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 4 reported tests for Lunenburg County over the 2008 to 2017 laboratory totals, with a median of 0.5 pCi/L: too few to describe a county (Radon411 reads a share from 30 tests up). Lunenburg County beside the counties around it is how this page reads it.
Only 4 tests were reported to CDC for Lunenburg 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.

Lunenburg County, Compared
CDC's largest figure for Lunenburg County rests on 5 tests over the 2005 to 2014 laboratory totals, 1 of them at or above 4 pCi/L, so each test moves its share by 20.0 points and no rank or comparison is drawn from it. Results reached as high as 4.5 pCi/L, with a middle value of 0.8 pCi/L.
Of the counties bordering it, 3 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 Mecklenburg County the smallest, 34.2%, with Brunswick County at 36.4% between. Farther out, Appomattox County (43 miles away) at 16.7%, Chesterfield County (47 miles away) at 30.5% and Campbell County (51 miles away) at 39.1% 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 Lunenburg County in Zone 2, its middle label: a predicted county average between 2 and 4 pCi/L. USGS geology rates 59% of the county's land high radon potential.

Lunenburg County, Geology
USGS's geologic map splits Lunenburg County: 59.5% of its land is high radon potential and 40.5% moderate. The map puts 59.5% of Lunenburg County in the area it calls Goochland Terrane and 40.5% in Carolina Terrane. USGS gives the first a radon index of 13, in the high band (12 to 17), and the second 10, in the moderate band (9 to 11).
| 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 | 59.5% |
| Carolina Terrane | Metavolcanic rocks, granite and granitic gneiss. | Moderate | 10 | 40.5% |
