Radon Levels in Chesapeake city, Virginia

EPA puts Chesapeake city in Zone 3, its lowest radon zone, and most reported tests there come back low, though 7.0% of 43 (2008 to 2017, laboratory totals) reached 4 pCi/L. Homes with elevated levels occur in all three zones, so only a test measures yours.

is EPA's lowest class, and its forecast for Chesapeake city as a whole is an average indoor of less than 2 pCi/L (less than 75 Bq/m³). A low zone clears no address in it: homes above EPA's turn up in all three zones.

Chesapeake city, Compared

Chesapeake city radon figures, compared

Calculated by Radon411

Chesapeake city reports fewer high tests than Virginia overall. 7.0% of its 43 tests over the 2008 to 2017 laboratory totals were at or above 4 pCi/L. That is 23.4 points below the 30.4% pooled from 131 Virginia counties.

Ordered from highest share down, it comes 81st of 84 Virginia counties with 30 or more tests for the same period. Nationally, every county with a figure for the same period pools to 35.7%; Chesapeake city sits 28.7 points below it.

Next door, the shares run from 2.7% in Norfolk city to 4.3% in Virginia Beach city, with Virginia Beach city and Norfolk city below Chesapeake city. Zone 3 on EPA's map (predicted average under 2 pCi/L) and a 7.0% share point the same way here.

Half the tests came in under 0.6 pCi/L and half over it; the single highest reached 8.3 pCi/L. The rest split 90.7% under 2 pCi/L and 2.3% from 2 to 4 (Virginia: 44.7% and 24.9%).

CDC's ten-year totals for Chesapeake city went from 46 tests (2005 to 2014) to 43 (2008 to 2017), the share going from 10.9% to 7.0%.

The ground under Chesapeake city

Predicted

USGS's geologic map puts all of Chesapeake city's mapped land in one class: low radon potential. All of it lies in the area the map calls Quaternary Coastal Plain Sediments, to which USGS gives a radon index of 6, in the low band (5 to 8).
