Radon is a naturally occurring radioactive gas that can enter a home from the ground and build up indoors. You can't see or smell it, and long-term exposure increases the risk of lung cancer. As the EPA explains, “Testing is the only way to know your level of exposure.”

​

Testing is especially important in North Georgia and metro Atlanta. EPA's Georgia map identifies Cobb, Fulton, DeKalb, and Gwinnett counties as Zone 1—the category with the highest potential for elevated indoor radon. UGA Extension also reports that North Georgia homes tend to have higher radon levels than homes elsewhere in the state. Still, a map or a neighbor's result cannot tell you what's happening inside your home. EPA's advice is clear: “All homes should be tested for radon.”

​

We use Airthings Corentium Pro continuous radon monitors, which feature four radon detection chambers working together and generate hourly readings. That record helps show how levels change during the testing period. We explain your overall test result and the recommended next steps, rather than leaving you to interpret a number on your own.

​

An elevated result doesn't make a home a bad house. It identifies a problem that can usually be addressed with a professionally designed radon mitigation system. EPA recommends fixing homes at 4 pCi/L or higher and considering mitigation between 2 and 4 pCi/L. Follow-up testing helps guide the decision, and testing after mitigation confirms that levels have been reduced. Because levels can change over time, radon testing belongs in your ongoing home care plan, too.

You can't see radon. You can take action.
