Radon tests reported for Petersburg city, 2008 to 2017, laboratory
CDC holds 7 reported tests for Petersburg city 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). Petersburg city beside the counties around it is how this page reads it.
What these figures count
Only 7 tests were reported to CDC for Petersburg 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).
Petersburg city, Compared
Petersburg city radon figures, compared
Calculated by Radon411CDC's largest figure for Petersburg city rests on 9 tests over the 2006 to 2015 laboratory totals, 0 of them at or above 4 pCi/L, so each test moves its share by 11.1 points and no rank or comparison is drawn from it. Results reached as high as 1.5 pCi/L, with a middle value of 0.5 pCi/L.
Chesterfield County, the one bordering county with a figure over the 2006 to 2015 laboratory totals, reported 30.5% of its tests at or above 4 pCi/L. Farther out, Richmond city (23 miles away) at 28.0%, Henrico County (23 miles away) at 25.7% and James City County (35 miles away) at 38.4% 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 Petersburg city 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 low radon potential.
Pooled shares: Radon411's sum of CDC's county counts for one period.
