North Carolina Radon

Elevated levels of radon have been found in many counties throughout North Carolina. Most homes in the coastal plains of North Carolina usually have low radon levels, while the upper piedmont and mountain areas have the greatest proportion of homes with elevated levels of radon. 

Radon is present in Greensboro, Winston Salem, Burlington, Raleigh, Durham, Cary, Chapel Hill, Apex, and the surrounding areas. 

Radon testing is performed using electronic monitors. The monitors are placed in the proper location for at least 48 hours. At the conclusion of the test, we send out a report showing the overall average. The EPA recommends mitigation when test results reveal an overall average of 4.0 pCi/ L or more.
