Georgia Radon Summary
Key Facts About Radon in Georgia
- North Georgia mountains (near Blue Ridge) have higher radon potential
- Metro Atlanta testing shows mixed results — worth testing individually

Georgia Testing Requirements & Recommendations
No state mandate. Georgia Environmental Protection Division recommends testing.
Standard EPA-approved mitigation methods are effective throughout Georgia.
Major Cities in Georgia
Radon levels can vary significantly within Georgia depending on local geology. All residents — regardless of city — should test their specific home, as neighborhood-level radon varies independently of broader state and county averages.
What Should Georgia Residents Do?
Test Your Home
Use a short-term charcoal test kit ($15–$25) for an initial reading, or a continuous radon detector for ongoing monitoring. Test in your basement or lowest livable area.
Understand Your Result
If your result is below 2.0 pCi/L: monitor periodically. Between 2.0–4.0 pCi/L: consider mitigation. Above 4.0 pCi/L: the EPA recommends mitigation. Above 8.0 pCi/L: take action promptly.
Hire a Certified Contractor if Needed
Look for NRPP or NRSB-certified radon mitigation contractors in Georgia. Mitigation systems typically cost $800–$2,500 and can reduce radon levels by 50–99%.
Verify with a Follow-Up Test
After mitigation, test again to confirm the system is working. Retest every 2 years, or after significant home renovations.
