Yes — if your Georgia home was built on soil (and all of them are), you should test for radon. Radon is a colorless, odorless radioactive gas that seeps up from the ground and can accumulate to dangerous levels indoors. The EPA recommends taking action when indoor radon reaches 4 picocuries per liter (pCi/L) or higher, and parts of North Georgia register elevated levels. Testing is the only way to know.

What Is Radon, and Why Should Georgia Homeowners Care?
Radon forms naturally when uranium in soil and rock breaks down. As it decays, it releases radioactive particles that, when inhaled over time, can damage lung tissue. The U.S. Environmental Protection Agency (EPA) and the Centers for Disease Control and Prevention identify radon as the second leading cause of lung cancer in the United States, behind only cigarette smoking.
What makes radon especially tricky is that you cannot see it, smell it, or taste it. It enters your home through cracks in foundation slabs, gaps around service pipes, crawlspace openings, and even through well water. A house that looks perfectly solid can still have a radon problem hidden inside.
Does Georgia Have a Radon Problem?
Georgia is not uniformly high-risk, but it is not uniform either. The EPA divides the country into three radon zones based on predicted average indoor levels:
- Zone 1 (highest potential): predicted average indoor radon above 4 pCi/L
- Zone 2 (moderate potential): predicted average between 2 and 4 pCi/L
- Zone 3 (lowest potential): predicted average below 2 pCi/L
Several counties in North Georgia — including parts of the Blue Ridge and Piedmont regions — fall in EPA Zone 1 or Zone 2. Central and coastal Georgia counties generally carry lower predicted averages, but predicted averages are not guarantees. Local geology, soil composition, how your home was built, and even how tightly you seal your windows in winter all affect the actual level inside your home. The Georgia Environmental Protection Division provides state-level guidance and resources on radon. The only definitive answer is a test of your specific home.
What Is the EPA Action Level?
The EPA action level is 4 pCi/L. If a test shows your home is at or above that threshold, the EPA recommends fixing the home — typically through a process called sub-slab depressurization, where a licensed contractor installs a pipe-and-fan system that draws radon from under the foundation and vents it safely outside.
The EPA also notes that there is no known safe level of radon exposure, and even homes testing between 2 and 4 pCi/L may warrant voluntary mitigation depending on your comfort level and your family’s health history. You can read the full EPA guidance in their Consumer’s Guide to Radon Reduction.
When Should You Test Your Home?
There is no single “trigger” moment — really, every home should have a baseline radon test. That said, certain situations make testing especially urgent:
- You are buying or selling a home (radon tests are common in real-estate transactions)
- Your home has a basement or a slab-on-grade foundation
- You or a family member spends significant time in a lower level of the home
- You have never tested, and your home was built before modern radon-resistant construction techniques became standard
- You recently completed foundation work, sealed crawlspace vents, or made significant changes to the home’s envelope
- You are concerned about overall indoor air quality (IAQ) — radon is one of several indoor pollutants worth knowing about
Short-term tests (typically 48–96 hours with a charcoal canister) give a quick snapshot. Long-term tests (90 days or more) reflect seasonal variation and provide a more accurate annual average. Your testing professional can help you choose the right approach.
How Does Radon Relate to Other Indoor Air Quality Concerns?
Radon is one piece of a broader indoor air quality picture. Homes also contend with mold, volatile organic compounds (VOCs), and — in older properties — asbestos-containing materials that can release fibers if disturbed. If you are already concerned about what is in your home’s air, a comprehensive IAQ assessment can address multiple hazards at once rather than treating each one in isolation.
ES America has provided environmental services — including mold inspections and mold remediation — across Georgia, South Carolina, and Alabama since 2009. As part of expanding our indoor air quality capabilities, we are adding radon testing services alongside our existing environmental offerings. If you want to ask about radon testing availability in your area, we invite you to call or email us directly.
What Happens After a Radon Test?
If your results come back below 2 pCi/L, most experts recommend re-testing every two years or after major renovations. If results fall between 2 and 4 pCi/L, discuss your options with your testing professional. If results come back at or above 4 pCi/L, a licensed radon mitigation contractor should evaluate your home and propose a remedy. Mitigation systems, when properly installed, typically reduce radon levels by up to 99%, according to the EPA.
Keep your test results on file. They are useful documentation for future buyers if you ever sell, and they establish a baseline you can compare against future tests.

Frequently Asked Questions About Radon in Georgia Homes
Is radon testing required when buying a home in Georgia?
Georgia does not legally require radon testing as part of a home sale, but many buyers — and a growing number of real-estate agents — request it as a standard part of the inspection process, particularly for homes in North Georgia counties with higher radon potential. Even if it is not required, it is a worthwhile investment given what a high radon level can mean for your family’s long-term health.
How much does a radon test cost?
We don’t publish fixed prices here because costs vary by test type (short-term vs. long-term), home size, and geographic area. Contact ES America at (404) 994-6006 or services@es-america.com to ask about current radon testing availability and pricing in your area.
Can I buy a DIY radon test kit?
Yes — short-term charcoal canister kits are sold at many hardware stores and online. They can give you a useful initial reading. That said, professional testing follows placement protocols designed to get the most accurate reading in the lowest livable area of your home, and a professional can help you interpret results and decide on next steps. For a result you can act on with confidence, professional testing is the better choice.
What is an acceptable radon level for a Georgia home?
The EPA sets its action level at 4 pCi/L. Levels below 2 pCi/L are generally considered low risk, though the EPA notes there is no completely safe level of radon. Levels between 2 and 4 pCi/L are in a gray zone where mitigation is worth discussing with a professional. The average indoor radon level in U.S. homes is approximately 1.3 pCi/L, according to the EPA.
Does radon affect all types of homes equally?
No. Homes with basements or slab-on-grade foundations in direct contact with soil tend to be more susceptible because radon’s entry point is typically the lowest level. However, crawlspace homes and even upper floors can accumulate radon if air movement draws it upward. The only reliable answer is a test of your actual home.
