Georgia Radon Facts & Statistics

The Radon Testing Gap Creates Preventable Risk

With only 12% of Georgia homes tested for radon, 88% of homeowners have no idea whether they're exposing their families to dangerous radon levels. In Metro Atlanta, where 1 in 4 to 1 in 3 tested homes exceed the EPA action level, this testing gap means thousands of families are unknowingly at risk.

Radon is a Silent Killer

Radon gas is invisible, odorless, and tasteless, you cannot detect it without testing. It causes no immediate symptoms, but long-term exposure damages lung cells and significantly increases lung cancer risk. Georgia sees over 400 radon-related lung cancer deaths each year, and many of these deaths are preventable with testing and mitigation.

Every Metro Atlanta County Has Radon Risk

The EPA classifies all Metro Atlanta counties, including Fulton, DeKalb, Gwinnett, Cobb, Forsyth, Cherokee, Clayton, Fayette, Henry, Rockdale, and Douglas, as Zone 2 (moderate radon potential). This means elevated radon levels are found throughout the region, regardless of specific neighborhood, home age, or foundation type. Testing is essential for every Metro Atlanta home.

Older Homes Face Greatest Risk

Homes built before 1990, common in established Atlanta neighborhoods like Buckhead, Decatur, Roswell, Marietta, and East Atlanta, were constructed without radon-resistant building codes. These homes show 40% higher radon prevalence than newer construction, yet are tested at significantly lower rates. If your home was built before 1990, testing is especially critical.

Radon Mitigation is Highly Effective

The good news: radon is a solvable problem. Professional mitigation systems reduce radon by up to 99%, with most homes dropping well below 2.0 pCi/L after installation. Mitigation is a one-time investment that protects your family for decades and increases your home's value by providing documentation of radon safety.

Test Your Home Immediately

Georgia data shows 1 in 4 to 1 in 3 tested homes exceed safe radon levels. Testing is the only way to know if your family is at risk.

• Professional testing provides accurate, lab-experienced results
• Test the lowest lived-in level of your home
• Conduct testing during heating season (November-March) for most accurate results
• Retest every 2 years or after major renovations

Understand Your Risk Level

Interpreting your radon test results correctly:

• Below 2.0 pCi/L: Low risk, retest periodically
• 2.0-4.0 pCi/L: Elevated, consider mitigation to reduce exposure
• 4.0-10.0 pCi/L: EPA action level, mitigation strongly recommended
• Above 10.0 pCi/L: High risk, immediate mitigation required

Install Professional Radon Mitigation

If testing shows radon above 4.0 pCi/L, professional mitigation is the proven solution. Our systems reduce radon by up to 99% and provide long-term protection for your family.

Educate Your Community

With only 12% of Georgia homes tested, radon awareness is critically low. Share your testing experience with neighbors, especially in older communities where risk is highest but testing rates are lowest. Public health depends on community action.
