Radon in Brookhaven, Georgia: What DeKalb County Homeowners Need to Know
Brookhaven is the second largest city in DeKalb County with a population exceeding 57,000. Incorporated in December 2012, Brookhaven spans 12 square miles of prime intown Atlanta real estate with a median home value of approximately $700,000. The same Piedmont geology that makes this area attractive for its rolling terrain also produces radon gas from uranium-bearing bedrock beneath every Brookhaven neighborhood.
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. 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.
A 2017 peer-reviewed study of DeKalb County homes published in the International Journal of Environmental Research and Public Health found that having a basement was the single strongest predictor of elevated radon. With Brookhaven's mix of new construction homes with basements and older mid-century ranches on slabs, radon risk varies significantly from property to property. Testing is the only way to know your home's levels.
Brookhaven Geology and Radon Risk
Brookhaven sits within the Piedmont physiographic province on bedrock composed primarily of biotite gneiss, granite, and Lithonia Gneiss. These metamorphic and igneous rocks contain uranium-bearing minerals, including zircon crystals with uranium and thorium, that produce radon gas as they decay. The Cecil sandy loam soil that overlies this bedrock throughout DeKalb County sits atop a saprolite layer 10 to 25 feet thick, which can serve 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. Faults create fractures in bedrock that serve as conduits for radon gas to travel upward through soil and into homes through foundation cracks, gaps around pipes, and sump pits.
Radon Testing Across Brookhaven Neighborhoods
Brookhaven's 27,000+ housing units range from 1950s ranch homes to brand-new construction, each with different radon risk profiles based on foundation type and proximity to DeKalb County's geological fault zones.
New Construction & Teardowns
Brookhaven's real estate market is one of the most active in metro Atlanta, with a median sale price around $700,000. Many mid-century ranches are being replaced with larger homes that include basements, which research shows are the strongest predictor of elevated radon in DeKalb County.
New construction does not mean radon-free. Modern homes with tight building envelopes and basement foundations can actually accumulate higher radon levels than the older homes they replace. Testing before and after construction is recommended.
Mid-Century Neighborhoods
Neighborhoods like Ashford Park, Drew Valley, and Lynwood Park feature 1950s-era ranch homes with slab and crawlspace foundations. These homes have different radon entry points than basement homes but still face risk from DeKalb County's uranium-bearing bedrock.
Cracks in concrete slabs, gaps around plumbing penetrations, and uncovered crawl spaces all provide pathways for radon gas to enter older Brookhaven homes. A radon test is the only way to determine your home's actual levels.
Condos & Townhomes
Brookhaven has significant condo and townhome development, particularly along Peachtree Road and near the Brookhaven MARTA station. Ground-floor and garden-level units are most susceptible to radon entry from the soil beneath the building.
Upper-floor units in multi-story buildings generally have lower radon risk, but ground-level units built on DeKalb County's granite bedrock should be tested. We work with HOAs and property managers to provide building-wide testing and mitigation solutions.
Schools, Daycares & Commercial
DeKalb County School District serves approximately 92,000 students across 138 schools. Brookhaven is home to Ashford Park Elementary, Montclair Elementary, Montgomery Elementary, and is served by Chamblee Middle and High Schools. Children are especially vulnerable to radon exposure.
We provide commercial radon testing and mitigation services for Brookhaven businesses, schools, daycares, and multi-family properties. Oglethorpe University and Georgia State University's Brookhaven campus are also in the service area.

Frequently Asked Questions About Radon in Brookhaven, GA
Common questions from DeKalb County homeowners about radon testing and mitigation
Why is radon a concern in Brookhaven and DeKalb County?
Brookhaven sits in Georgia's Piedmont region on biotite gneiss and granite 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 elevated radon levels, and the county recorded a high reading of 95.6 pCi/L—nearly 24 times the EPA action level of 4.0 pCi/L.
What is the average radon level in Brookhaven, GA?
DeKalb County has a reported average indoor radon level of approximately 2.2 pCi/L based on Air Chek testing data. While this average falls below the EPA action level of 4.0 pCi/L, nearly 1 in 5 homes tested in DeKalb County exceeded that threshold. Radon levels vary significantly from home to home depending on foundation type, soil conditions, and proximity to geological fault zones. A peer-reviewed study found that homes with basements in DeKalb County were the most likely to have elevated radon.
Does the type of foundation affect radon levels in Brookhaven homes?
Yes. A peer-reviewed study of DeKalb County homes published in the International Journal of Environmental Research and Public Health found that having a basement was the single strongest predictor of elevated radon levels. Many newer Brookhaven homes are built with basements, while older mid-century ranches typically have slab or crawlspace foundations. Regardless of foundation type, the EPA recommends testing all homes.
How much does radon mitigation cost in Brookhaven?
Radon mitigation systems in Brookhaven 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. Sub-slab depressurization is the most common and effective method for Brookhaven homes built on slab foundations, while sub-membrane depressurization is used for crawl spaces. We provide free estimates so you know the cost before any work begins.
How do geological fault zones affect radon in Brookhaven?
DeKalb County has four mapped geological fault zones: Ball Mill, Long Island, Oakdale, and Rivertown. Research published in the journal Science of the Total Environment found that proximity to fault zones was a stronger predictor of elevated radon than the type of rock beneath a home. Fault zones create fractures in bedrock that serve as pathways for radon gas to migrate upward into homes.
How long does radon testing take in Brookhaven?
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 Brookhaven, we offer 48-hour turnaround to keep deals on schedule.
Should I test for radon when buying a Brookhaven home?
Yes. With DeKalb County recording the highest single radon reading of any metro Atlanta county at 95.6 pCi/L, radon testing is an important part of any Brookhaven home purchase. The active real estate market in Brookhaven means homes sell quickly, and radon testing during the inspection period protects your investment. If elevated levels are found, mitigation can often be negotiated as part of the sale.
What type of radon mitigation system works best for Brookhaven homes?
Sub-slab depressurization (SSD) is the most effective radon remediation method for Brookhaven homes with slab or basement foundations. The system creates negative pressure beneath your foundation to intercept radon before it enters your living space. For older Brookhaven homes with crawl spaces, sub-membrane depressurization is used instead. Both systems typically reduce radon levels by 90% or more.
