Georgia (GA) - Radon Levels & Risk Assessment
Georgia is classified as EPA Zone 2 (Moderate Potential) for radon potential, with an average indoor radon level of 2.5 pCi/L. While below the EPA action level of 4.0 pCi/L, many individual homes test above the threshold and the EPA recommends considering mitigation even at these levels. Approximately 14% of homes in Georgia have radon levels above 4.0 pCi/L.

Radon Risk in Georgia
As an EPA Zone 2 (Moderate Potential) state, Georgia has moderate radon potential. While not in the highest-risk category, many homes in the state test above the EPA action level, especially those with basements or those built on certain geological formations. The average indoor radon level of 2.5 pCi/L is below the EPA action level but above the level where the EPA suggests considering mitigation.
Testing and Mitigation in Georgia
While Georgia does not mandate radon testing, it is strongly recommended by both the EPA and state health agencies. Many home buyers include radon testing as part of their home inspection. The average cost of radon mitigation in Georgia is $1,200, which is near the national average. Professional radon testers and mitigators in Georgia can be found through the NRPP (National Radon Proficiency Program) or the NRSB (National Radon Safety Board) directories.
Protecting Your Home in Georgia
The EPA recommends that all homes in Georgia be tested for radon, regardless of the state's overall zone classification. If your home tests at 4.0 pCi/L or above, install a mitigation system. If your home tests between 2.0 and 4.0 pCi/L, the EPA suggests considering mitigation. New construction in Georgia may benefit from radon-resistant building techniques (RRNC), which are inexpensive to include during construction and can be easily activated later if radon levels are found to be elevated.
