Radon Levels in Henderson County, Kentucky
The average indoor radon level in Henderson County is 3.4 pCi/L — about 2.6× the U.S. average of 1.3 pCi/L, and below the EPA action level of 4.0 pCi/L (CDC National Environmental Public Health Tracking Network, 2008–2017). While the county average is below the action level, radon varies home to home — elevated readings still occur throughout Henderson County, so the EPA recommends every home be tested.

What This Means for Henderson County Homeowners
A below-action-level county average does not mean your home is safe — radon depends on your home's foundation, soil, and construction. Plenty of homes in lower-average counties still test well above 4.0 pCi/L. A short-term test kit ($15–30) is the only way to know. Either way, Kentucky Radon Experts routes you to a verified Kentucky partner contractor for testing or mitigation.
