Montgomery County, KY radon potential

EPA places Montgomery County in Zone 2 - Moderate Potential — a predicted county-wide average indoor radon level between 2 and 4 pCi/L, based on the geology, soil and aerial radioactivity data behind EPA's national map. Nationally, Montgomery County ranks higher in radon potential than 50% of rated counties (the 50th percentile).

Montgomery County by the numbers

Montgomery County, Kentucky is home to about 28,771 people across 197.377 square miles. Averaged across its land area, Montgomery County runs about 146 people per square mile.

EPA's geology-based Region 4 groups Montgomery County with 735 other counties nationally sharing its underlying rock and soil profile.

Why the zone isn't the answer by itself

Call it a middle case: above the 1.3 pCi/L most US homes average, below the 4 pCi/L line EPA uses to recommend mitigation — that's Montgomery County's Zone 2 prediction. Nothing about a Zone 2 label lowers the case for testing in Montgomery County — EPA recommends it in every zone, moderate included.

Next steps for a home in Montgomery County

A short-term test kit is the standard first step and typically costs far less than mitigation itself. If a test comes back at or above 4 pCi/L, a radon mitigation system for a typical home runs roughly $800–$2,500 (around $1,200 for a common single-family install), driven mainly by foundation type, not by county.
