Radon levels in Georgia: Low

The model predicts a population-weighted basement average of 1.9 pCi/L across Georgia's 159 counties - close to the US average of 1.8 pCi/L. Above-ground floors average 1.0 pCi/L.

Predicted (model estimate). The pCi/L figures on this page are long-term area averages from a peer-reviewed national model built on millions of real radon tests (2001-2021). They describe the typical home in this area - not your home, which can be several times higher or lower. The EPA radon zone is a separate, 1993 county-level classification. How the numbers work.

Georgia radon questions

Is radon high in Georgia?
Georgia's population-weighted predicted basement average is 1.9 pCi/L, close to the US average of 1.8. 0 of its 159 modeled counties are predicted at or above the EPA action level of 4 pCi/L, 44 are in the 2-4 "consider fixing" range and 115 are below 2. 0% of Georgia ZIP codes are predicted at 4 or higher.
Which Georgia county has the highest radon?
Walton County has the highest predicted basement average in Georgia at 2.8 pCi/L (EPA Zone 2). The lowest is Lanier County at 1.3 pCi/L. These are modeled area averages; individual homes in any county can test far higher.
How many EPA Zone 1 counties are in Georgia?
4 of Georgia's 159 counties (3%) are EPA Zone 1 (highest potential), 55 are Zone 2 and 100 are Zone 3. The EPA zone map dates from 1993; the predicted values on this page come from a 2001-2021 model built on millions of actual tests, so the two can disagree for a given county.
Should I test for radon in Georgia?
Yes. Even though Georgia's predicted average is below 2 pCi/L, the EPA recommends every home be tested - radon varies house to house, and 29.1% of Georgia ZIP codes are still predicted at 2 pCi/L or higher.
