Radon Levels in Berrien County, Georgia

EPA puts Berrien County in Zone 3, its lowest radon zone, and only 1 radon test from it is on file with CDC (2008 to 2017, laboratory totals). Homes with elevated levels occur in all three zones, so only a test measures yours.

Predicted: EPA radon zone

EPA Zone 3: lower predicted potential

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

Measured: tests reported to CDC

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

CDC holds 1 reported test for Berrien County over the 2008 to 2017 laboratory totals, a result of 1.1 pCi/L: too few to describe a county (Radon411 reads a share from 30 tests up). Berrien County beside the counties around it is how this page reads it.

What these figures count

Only 1 test was reported to CDC for Berrien 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).

Berrien County, Compared

Berrien County radon figures, compared

Calculated by Radon411

CDC's largest figure for Berrien County rests on 1 test over the 2008 to 2017 laboratory totals, 0 of them at or above 4 pCi/L, so each test moves its share by 100.0 points and no rank or comparison is drawn from it. Results reached as high as 1.1 pCi/L, with a middle value of 1.1 pCi/L.

The nearest counties with a figure are Dougherty County (61 miles away) at 0.0%, Laurens County (84 miles away) at 16.1% and Houston County (85 miles away) at 8.2%. 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 Berrien 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.

Berrien County, Geology

The ground under Berrien County

Predicted

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