Pulaski County by the numbers

Pulaski County, Kentucky is home to about 66,842 people across 658.106 square miles. That works out to roughly 102 people per square mile.

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

Why the zone isn't the answer by itself

Pulaski County's predicted average sits above EPA's own action level of 4 pCi/L — the concentration at which EPA recommends fixing a home — versus a national average around 1.3 pCi/L indoors and 0.4 pCi/L outdoors. Some Pulaski County homes will test comfortably under the action level despite the county's Zone 1 rating — the only way to know which kind of home you have is an actual test.

Testing and mitigation in Pulaski 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.
