Radon tests reported for Suffolk city, 2008 to 2017, laboratory
CDC holds 5 reported tests for Suffolk 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). Suffolk city beside the counties around it is how this page reads it.
What these figures count
Only 5 tests were reported to CDC for Suffolk 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).
Suffolk city, Compared
Suffolk city radon figures, compared
Calculated by Radon411CDC's largest figure for Suffolk city rests on 6 tests over the 2007 to 2016 laboratory totals, 0 of them at or above 4 pCi/L, so each test moves its share by 16.7 points and no rank or comparison is drawn from it. Results reached as high as 3.1 pCi/L, with a middle value of 1.2 pCi/L.
Chesapeake city, the one bordering county with a figure over the 2006 to 2015 laboratory totals, reported 7.0% of its tests at or above 4 pCi/L. Farther out, Norfolk city (25 miles away) at 5.3%, Newport News city (29 miles away) at 5.9% and Virginia Beach city (33 miles away) at 7.4% 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 Suffolk city in Zone 3, its lowest label: a predicted county average under 2 pCi/L. USGS geology rates 98% of the county's land low radon potential.

The ground under Suffolk city
PredictedUSGS's geologic map puts all of Suffolk city's mapped land in one class: low radon potential. The map puts 75.4% of Suffolk city in the area it calls Tertiary Coastal Plain Sediments and 22.8% in Quaternary Coastal Plain Sediments. USGS gives the first a radon index of 8 and the second 6, both 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 | 75.4% |
| Quaternary Coastal Plain Sediments | Quaternary coastal sand and silt containing monazite. | Low | 6 | 22.8% |

Suffolk city beside the ground around it
Across Virginia 47.9% of the land is rated high; none of Suffolk city's is. None of the 6 counties that border it has any moderate-potential ground either.
