Radon Levels in Fayette County, Kentucky
The average indoor radon level in Fayette County is 8.1 pCi/L — about 6.2× the U.S. average of 1.3 pCi/L, and above the EPA action level of 4.0 pCi/L (CDC National Environmental Public Health Tracking Network, 2008–2017). That means the typical home here tests high enough that the EPA recommends installing a radon mitigation system — testing is strongly advised across Lexington and the rest of the county.

What This Means for Fayette County Homeowners
Because the county average sits above the EPA's 4.0 pCi/L action level, radon mitigation is commonly needed here. The fix is routine: an NRPP-certified contractor installs an active sub-slab depressurization system that vents soil gas above the roofline, typically reducing indoor radon by 70–99%. Either way, Kentucky Radon Experts routes you to a verified Kentucky partner contractor for testing or mitigation.
