Why is radon especially concerning in Georgia?

Georgia has varying radon levels depending on geology. North Georgia counties in the Blue Ridge and Appalachian foothills are EPA Zone 1 -- elevated radon risk due to bedrock composition. Zone 2-3 conditions exist elsewhere in the state. UGA Extension's Georgia Radon Program publishes county-level radon data.

Are radon testers required to be certified in Georgia?

Certification requirements vary by state. The Georgia Radon Program (UGA Extension) and professional organizations like the National Radon Proficiency Program (NRPP) or National Radon Safety Board (NRSB) recommend certified testers. For real estate transactions, use a certified professional to ensure legally defensible results.

What happens if my Georgia home has high radon levels?

If radon levels exceed 4 pCi/L, the EPA and Georgia Radon Program (UGA Extension) recommend installing a radon mitigation system. Sub-slab depressurization is the most effective method and typically costs $1,000 to $2,000. State-certified contractors can perform mitigation. Mitigation reduces levels by up to 99%.

When should I test for radon in my Georgia home?

The Georgia Radon Program (UGA Extension) recommends testing all homes, especially in north Georgia's EPA Zone 1 counties. Test when buying or selling, after major renovations affecting the foundation, or if you have never tested. Testing during cooler months (November through March) with windows closed provides the most representative results. Re-test every 2 years or after major changes to the home.
