Radon Levels in Bulloch County, Georgia

EPA puts Bulloch County in Zone 3, its lowest radon zone, and only 21 radon tests from it are on file with CDC (2008 to 2017, laboratory totals). Homes with elevated levels occur in all three zones, so only a test measures yours.

EPA Zone 3: lower predicted potential

is EPA's lowest class, and its forecast for Bulloch County 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.

Radon tests reported for Bulloch County, 2008 to 2017, laboratory

CDC holds 21 reported tests for Bulloch County over the 2008 to 2017 laboratory totals, with a median of 0.2 pCi/L: too few to describe a county (Radon411 reads a share from 30 tests up). Bulloch County beside the counties around it is how this page reads it.

What these figures count

Only 21 tests were reported to CDC for Bulloch County 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).

Bulloch County, Compared

Bulloch County radon figures, compared

Calculated by Radon411

CDC's largest figure for Bulloch County rests on 22 tests over the 2007 to 2016 laboratory totals, 0 of them at or above 4 pCi/L, so each test moves its share by 4.5 points and no rank or comparison is drawn from it. Results reached as high as 3.0 pCi/L, with a middle value of 0.4 pCi/L.

The nearest counties with a figure are Chatham County (45 miles away) at 0.0%, Laurens County (69 miles away) at 16.1% and Richmond County (69 miles away) at 0.0%. Pooled across 137 Georgia counties, 23.9% of reported tests reached that level; across every county in the country with a figure, 35.8%.

Statewide for the same period, Barrow County reported the highest share (51.0%) and Dougherty County the lowest (0.0%). EPA's 1993 map puts Bulloch County 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.

Predicted

USGS's geologic map puts all of Bulloch County's mapped land in one class: low radon potential. The map puts 65.0% of Bulloch County in the area it calls Coastal Plain and 35.0% in Coastal Plain. USGS gives the first a radon index of 8 and the second 7, both in the low band (5 to 8).
