Locations and reports
EPA puts New Kent County in Zone 3, its lowest radon zone, and only 13 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 13 reported tests for New Kent County over the 2008 to 2017 laboratory totals, with a median of 2.4 pCi/L: too few to describe a county (Radon411 reads a share from 30 tests up). New Kent County beside the counties around it is how this page reads it.
Only 13 tests were reported to CDC for New Kent 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).
New Kent County, Compared
CDC's largest figure for New Kent County rests on 14 tests over the 2007 to 2016 laboratory totals, 5 of them at or above 4 pCi/L, so each test moves its share by 7.1 points and no rank or comparison is drawn from it. Results reached as high as 29.1 pCi/L, with a middle value of 2.5 pCi/L.
Of the counties bordering it, 3 have a figure over the 2006 to 2015 laboratory totals: James City County reported the largest share at or above 4 pCi/L, 38.4%, and Hanover County the smallest, 16.0%, with Henrico County at 25.7% between. Farther out, Richmond city (26 miles away) at 28.0%, Chesterfield County (34 miles away) at 30.5% and Newport News city (38 miles away) at 5.9% 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 New Kent County in Zone 3, its lowest label: a predicted county average under 2 pCi/L. USGS geology rates 95% of the county's land low radon potential.

New Kent County, Geology
USGS's geologic map puts all of New Kent County's mapped land in one class: low radon potential. 95.1% 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 | 95.1% |

Across Virginia 47.9% of the land is rated high; none of New Kent County's is. Of the 6 counties that border it, 2 have more high-potential ground, Hanover County the most at 52.2%.
