Radon tests reported for Franklin city, 2008 to 2017, laboratory
CDC holds 2 reported tests for Franklin city over the 2008 to 2017 laboratory totals, with a median of 0.9 pCi/L: too few to describe a county (Radon411 reads a share from 30 tests up). Franklin city beside the counties around it is how this page reads it.
What these figures count
Only 2 tests were reported to CDC for Franklin city 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).
Franklin city, Compared
Franklin city radon figures, compared
Calculated by Radon411CDC's largest figure for Franklin city 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 0.9 pCi/L, with a middle value of 0.9 pCi/L.
The nearest counties with a figure are Chesapeake city (35 miles away) at 7.0%, Newport News city (37 miles away) at 5.9% and Norfolk city (40 miles away) at 5.3%. 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 Franklin city 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.

The ground under Franklin city
PredictedUSGS's geologic map puts all of Franklin city'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% |

Franklin city beside the ground around it
Across Virginia 47.9% of the land is rated high; none of Franklin city's is. None of the 2 counties that border it has any moderate-potential ground either.
