DeKalb County Radon Research: What Metro Atlanta Homeowners Need to Know
Scientific analysis reveals elevated radon levels across DeKalb County neighborhoods — and what it means for your home's safety
Study Overview
DeKalb County, one of Metro Atlanta's most populous counties, has been the subject of extensive radon research by environmental health scientists at Georgia State University. This comprehensive study analyzed radon concentration patterns across residential properties, identifying significant health risks for homeowners who remain unaware of radon presence in their homes.
The research utilized advanced radon detection methodologies to map radon levels across diverse neighborhoods, revealing that radon exposure is not limited to specific geographic pockets but affects homes throughout the county regardless of property age, value, or location.
Key Findings from This Case Study
- Widespread Radon Presence: Multiple neighborhoods across DeKalb County showed radon levels exceeding 4.0 pCi/L, the EPA's recommended action threshold
- No Immunity by Location: Both older and newer construction homes demonstrated elevated radon levels, dispelling myths that new homes are radon-free
- Foundation Vulnerabilities: Homes with basement foundations and slab-on-grade construction both showed radon infiltration, though entry points varied
- Seasonal Variations: Radon levels fluctuated seasonally, with higher concentrations typically measured during colder months when homes are sealed
- Low Testing Rates: Despite elevated radon levels, the study found that fewer than 10% of DeKalb County homeowners had conducted radon testing
Why This Matters for Metro Atlanta Homes
DeKalb County's findings are particularly significant because they mirror radon patterns across Metro Atlanta. The county's diverse geology, urban development patterns, and housing stock are representative of the broader Atlanta metropolitan area.
Geographic Implications: If you live in Decatur, Tucker, Dunwoody, Brookhaven, Stone Mountain, or any DeKalb County community, this research directly applies to your home. Similar radon risks exist in neighboring Gwinnett, Fulton, and Cobb counties.
Health Risk Context: Radon is the second leading cause of lung cancer after smoking. Long-term exposure to elevated radon levels significantly increases cancer risk, making professional radon testing and mitigation essential for protecting your family's health.
How Radon Enters Homes Like Yours
The DeKalb County study identified multiple radon entry pathways common in Metro Atlanta homes:
Foundation Cracks and Gaps
Georgia's clay soil expands and contracts with moisture, creating foundation cracks that allow radon gas to seep into basements and crawl spaces.
Slab-On-Grade Openings
Utility penetrations, expansion joints, and control joints in concrete slabs provide direct pathways for soil gas containing radon to enter living spaces.
Crawl Space Ventilation
Poorly sealed or inadequately ventilated crawl spaces allow radon accumulation that migrates upward into main living areas through floor gaps and HVAC ductwork.
Well Water (Secondary Source)
While soil gas is the primary radon source, homes using private well water may experience additional radon release when water is used for showering and household purposes.

Recommended Testing & Mitigation Actions
- Schedule Professional Radon Testing: Contact a certified radon contractor to conduct a comprehensive radon test using EPA-approved continuous radon monitors for accurate measurement
- Test Lowest Living Level: Radon testing should occur in your basement or lowest regularly occupied floor where radon concentrations are typically highest
- Conduct Long-Term Testing: For homes with initial elevated results, long-term testing (90+ days) provides annual average radon levels for informed mitigation decisions
- Install Radon Mitigation System if Needed: If test results exceed 4.0 pCi/L, professional radon mitigation using sub-slab depressurization can reduce radon levels by 90-99%
- Retest After Mitigation: Post-mitigation testing verifies system effectiveness and ensures radon levels remain below EPA action levels
- Annual Retesting: Even with mitigation systems, annual radon testing ensures continued protection and system functionality
