Radon in Dunwoody, Georgia: What Homeowners Need to Know
Dunwoody is a city of over 51,000 residents in DeKalb County, incorporated in December 2008. Spanning 13.2 square miles along the I-285 and GA-400 corridor, Dunwoody is home to the Perimeter Center business district, established residential neighborhoods, and a median home value exceeding $625,000. The Piedmont bedrock beneath Dunwoody contains uranium-bearing metamorphic and igneous rocks that produce radon gas, making radon awareness critical for both homeowners and businesses.
The UGA Georgia Radon Program identifies DeKalb County as one of the four highest-risk metro Atlanta counties for radon. According to UGA Extension data, approximately 18.9% of homes tested in DeKalb County had radon levels above the EPA action level of 4.0 pCi/L. The county recorded a high reading of 95.6 pCi/L, nearly 24 times the EPA threshold and the highest single reading recorded in any metro Atlanta county.
Radon is the second leading cause of lung cancer in the United States. In Georgia alone, approximately 800 people die each year from radon-related lung cancer. Radon is the leading cause of lung cancer among non-smokers. Because radon is odorless, colorless, and tasteless, the only way to know your home's radon level is through testing.
Many Dunwoody neighborhoods were developed between the 1960s and 1980s, with homes featuring split-level designs and basement foundations built directly into the hillside terrain. A peer-reviewed study of DeKalb County homes found that having a basement was the single strongest predictor of elevated radon. Whether you live in Dunwoody Village, Georgetown, Dunwoody Club Forest, or near Perimeter Center, your home's radon levels depend on the specific geology and foundation beneath your property.
Dunwoody Geology and Radon Risk
Dunwoody sits within the Piedmont physiographic province on bedrock composed of biotite gneiss, granite, and mica schist. These metamorphic and igneous rocks contain uranium-bearing minerals that produce radon gas as they decay. The rolling terrain that defines Dunwoody's landscape was shaped by millions of years of weathering on this bedrock, creating a saprolite layer 10 to 25 feet thick that serves as a pathway for radon migration into homes.
DeKalb County has four mapped geological fault zones: Ball Mill, Long Island, Oakdale, and Rivertown. Research published in Science of the Total Environment found that proximity to these fault zones was a stronger predictor of elevated radon than rock type alone. The fractures created by these faults serve as conduits for radon gas to travel upward through soil and into buildings through foundation cracks, gaps around utility penetrations, and sump pits.
Radon Testing Across Dunwoody Neighborhoods
Dunwoody's neighborhoods span five decades of development, from 1960s Georgetown to ongoing redevelopment near Perimeter Center. Each area has different housing styles and foundation types that affect radon risk.
1970s-80s Split-Levels & Basements
Dunwoody Club Forest, Dunwoody North, and surrounding neighborhoods feature thousands of homes built in the 1970s and 1980s with split-level and basement foundations. Dunwoody North alone has over 1,250 homes. These foundation types have the most soil contact and the highest radon risk according to peer-reviewed research.
Basements built into Dunwoody's hillside terrain are especially susceptible. Cracks in foundation walls, floor-wall joints, and sump pits all provide entry points for radon gas migrating upward through DeKalb County's weathered bedrock.
Dunwoody Village & Georgetown
Dunwoody Village, with its Colonial Williamsburg architecture dating to the early 1970s, and Georgetown, developed in the 1960s, represent some of Dunwoody's earliest residential communities. These established neighborhoods include a mix of foundation types from slab to crawl space to full basements.
Older homes may have more cracks and gaps in their foundations from decades of settling, creating additional pathways for radon entry. Whether your home has a slab, crawl space, or basement, testing is the only way to know your radon levels.
Perimeter Center Commercial District
The Perimeter Center area contains approximately 29 million square feet of office space and 6 million square feet of retail, home to UPS world headquarters, AT&T Mobility, and Cox Enterprises. All of this commercial space is built on the same radon-producing Piedmont bedrock as Dunwoody's residential areas.
Ground-floor offices, retail spaces, and any below-grade areas in Perimeter Center buildings should be tested for radon. We provide commercial radon testing and mitigation with compliance documentation for businesses, property managers, and building owners.
Schools & Families
Dunwoody is served by DeKalb County School District, including Dunwoody High School, Peachtree Charter Middle School, and elementary schools including Vanderlyn, Austin, Chestnut Charter, Dunwoody Elementary, Hightower, and Kingsley Charter. Children are especially vulnerable to radon exposure.
We provide radon testing and mitigation services for Dunwoody schools, daycares, and childcare facilities. Protecting children from radon exposure in the buildings where they spend most of their time is critical.

Frequently Asked Questions About Radon in Dunwoody, GA
Common questions from Dunwoody homeowners and businesses about radon testing and mitigation
Why is radon a concern in Dunwoody and DeKalb County?
Dunwoody sits in Georgia's Piedmont region on metamorphic and igneous bedrock that naturally contains uranium. The UGA Georgia Radon Program identifies DeKalb County as one of the four highest-risk metro Atlanta counties for radon alongside Fulton, Cobb, and Gwinnett. According to UGA Extension data, approximately 18.9% of homes tested in DeKalb County had radon levels above the EPA action level of 4.0 pCi/L, and the county recorded a high reading of 95.6 pCi/L—nearly 24 times the EPA threshold.
What is the average radon level in Dunwoody, GA?
DeKalb County has a reported average indoor radon level of approximately 2.2 pCi/L. While this average is below the EPA action level of 4.0 pCi/L, nearly 1 in 5 homes tested exceeded the threshold. Dunwoody homes built in the 1970s and 1980s with basement foundations are particularly susceptible to elevated radon levels. A peer-reviewed study of DeKalb County found that having a basement was the single strongest predictor of elevated radon.
Are 1970s and 1980s Dunwoody homes at higher radon risk?
Many Dunwoody neighborhoods were developed in the 1970s and 1980s with split-level and basement foundations built directly on DeKalb County's granite and gneiss bedrock. These homes often have more foundation contact with soil and more potential entry points for radon gas than newer slab-on-grade construction. However, all Dunwoody homes should be tested regardless of age, as radon levels depend on the specific geology beneath each property.
How much does radon mitigation cost in Dunwoody?
Radon mitigation systems in Dunwoody typically cost between $1,200 and $2,500 for standard residential installations. The final cost depends on your home's foundation type, size, and the complexity of the system required. Split-level and basement homes common in Dunwoody neighborhoods like Dunwoody Club Forest and Dunwoody North may require specific system configurations. We provide free estimates so you know the cost before any work begins.
Does the Perimeter Center area need commercial radon testing?
Yes. The Perimeter Center business district contains approximately 29 million square feet of office space and 6 million square feet of retail space, all built on the same Piedmont bedrock that produces radon throughout DeKalb County. Ground-floor offices, retail spaces, and buildings with below-grade levels should be tested. We provide commercial radon testing and mitigation with compliance documentation for Perimeter Center businesses.
How long does radon testing take in Dunwoody?
Short-term radon tests take 48 to 96 hours and provide a snapshot of your home's radon levels. We use professional continuous radon monitors that record hourly readings for the most accurate results. For real estate transactions in Dunwoody, we offer 48-hour turnaround to keep deals on schedule.
Should I test for radon when buying a Dunwoody home?
Yes. Dunwoody's median home price exceeds $625,000, making radon testing a smart investment to protect both your health and your property value. With DeKalb County recording the highest single radon reading in metro Atlanta at 95.6 pCi/L, testing during the inspection period is strongly recommended. If elevated levels are found, mitigation can often be negotiated as part of the sale.
What type of radon mitigation system works best for Dunwoody homes?
Sub-slab depressurization (SSD) is the most effective radon remediation method for Dunwoody homes with slab or basement foundations. For the split-level homes common in many Dunwoody neighborhoods, the system can be designed to address multiple foundation levels. For homes with crawl spaces, sub-membrane depressurization is used instead. Both systems typically reduce radon levels by 90% or more.
