EPA Zone 3: lower predicted potential

is EPA's lowest class, and its forecast for Lowndes 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 Lowndes County, 2008 to 2017, laboratory

CDC holds 9 reported tests for Lowndes County over the 2008 to 2017 laboratory totals, with a median of 1.1 pCi/L: too few to describe a county (Radon411 reads a share from 30 tests up). Lowndes County beside the counties around it is how this page reads it.

What these figures count

Only 9 tests were reported to CDC for Lowndes 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).

Lowndes County, Compared

Lowndes County radon figures, compared

Calculated by Radon411

CDC's largest figure for Lowndes County rests on 19 tests over the 2006 to 2015 laboratory totals, 0 of them at or above 4 pCi/L, so each test moves its share by 5.3 points and no rank or comparison is drawn from it. Results reached as high as 2.9 pCi/L, with a middle value of 0.2 pCi/L.

The nearest counties with a figure are Dougherty County (74 miles away) at 0.0%, Laurens County (114 miles away) at 16.1% and Houston County (114 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 Lowndes 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.

The ground under Lowndes County

Predicted

USGS's geologic map puts all of Lowndes 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).
