Why Test for Radon in Atlanta?
It's not just an "old house" problem. It's a geology problem.
The Granite Factor
Atlanta sits on a massive geological formation rich in granite (think Stone Mountain). As uranium in this rock breaks down, it releases radioactive radon gas. This gas seeps into basements and crawlspaces through cracks in the foundation.
Zone 1 High Risk Area
The EPA designates

Cobb
-
Fulton
-
DeKalb

Gwinnett
counties as "Zone 1," meaning they have the highest potential for elevated radon levels. 1 in 5 homes in Metro Atlanta tests high for radon.
Our Method: Continuous Radon Monitors (CRM)
We use state-of-the-art electronic Continuous Radon Monitors. This is the gold standard for real estate transactions, providing the most detailed and tamper-resistant data available.
•High Accuracy: Our monitors record hourly fluctuations, allowing us to see exactly how radon levels behave over time rather than providing just a single average.
•Tamper-Resistant Technology: Our CRMs feature built-in motion sensors and environmental trackers (measuring shifts in pressure and humidity) to ensure the integrity of the test throughout the 48-hour window.
•Same-Day Results: By eliminating the need for lab shipping and analysis, we provide your results immediately after the 48-hour testing period.
The Testing Process
1
Deployment
We place a professional Continuous Radon Monitor (CRM) in the lowest livable level of the home (basement or first floor) at the start of the inspection. These advanced electronic devices provide high-precision hourly readings.
2
48-Hour Exposure
3
Instant Results
We retrieve the device and download the data immediately on-site. Unlike charcoal canisters, there is no lab wait time or shipping delay. You receive a detailed, hourly report the same day the test is completed.
The CRM monitors the air for a minimum of 48 hours. During this time, the device tracks radon levels, humidity, and temperature. Windows and doors must remain closed to ensure a valid "closed-house" test environment.
Frequently Asked Questions About Radon
What is radon?
Radon is a naturally occurring radioactive gas that comes from the breakdown of uranium in soil, rock, and water. It can seep into homes through cracks in the foundation, crawlspaces, and other openings. You can’t see, smell, or taste radon, which makes it especially dangerous if left undetected.
Is radon really dangerous?
Yes. According to the EPA, radon exposure is the second leading cause of lung cancer in the United States, after smoking. Long-term exposure to high radon levels increases your risk of developing lung cancer, even if you don’t smoke. Any radon level at or above 4.0 pCi/L (picocuries per liter) should be reduced.
How do I know if my home has radon?
The only way to know is to test your home. Radon levels vary greatly from house to house, even in the same neighborhood. Professional radon testing provides accurate, detailed measurements, so you can find out if you need to take action.
How often should I test for radon?
It’s recommended to test your home for radon every two years, or after any major renovations that affect your foundation or ventilation. You should also test whenever you buy or sell a home, or if you've never tested before.
What do I do if my home has high radon levels?
If your radon levels are high (4.0 pCi/L or above), you should install a radon mitigation system, which usually involves venting radon gas from beneath your home to the outside. Professional mitigation companies can design and install these systems to reduce radon to safe levels.
How long does radon testing take?
Overall, the process takes approximately 2 days (48 hours). For real estate transactions, radon testing requires a minimum 48-hour monitoring period. We use state-of-the-art Continuous Radon Monitors (CRM). As soon as the 48-hour test is complete, the data is downloaded and a professional report is generated immediately. You will receive your results the same day the device is picked up.
