Radon tests reported for Emporia city, 2008 to 2017, laboratory
CDC holds 2 reported tests for Emporia city over the 2008 to 2017 laboratory totals, with a median of 3.1 pCi/L: too few to describe a county (Radon411 reads a share from 30 tests up). Emporia city beside the counties around it is how this page reads it.
What these figures count
Only 2 tests were reported to CDC for Emporia 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).
Emporia city, Compared
Emporia city radon figures, compared
Calculated by Radon411CDC's largest figure for Emporia city rests on 2 tests over the 2008 to 2017 laboratory totals, 1 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 4.4 pCi/L, with a middle value of 3.1 pCi/L.
The nearest counties with a figure are Brunswick County (19 miles away) at 36.4%, Mecklenburg County (46 miles away) at 34.2% and Chesterfield County (47 miles away) at 30.5%. 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 Emporia 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.

|---|---|---|---|---|
| Tertiary Coastal Plain Sediments | Tertiary Coastal Plain sand, silt, clay | Low | 8 | 100% |
