Cherokee County, AL: EPA's radon zone, explained

EPA places Cherokee 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. Cherokee County sits at the 49th percentile nationally for radon potential — above 49 of every 100 rated counties.

Zone vs. an actual test

Cherokee County's predicted average falls between EPA's 4 pCi/L action level and the national indoor average of about 1.3 pCi/L (outdoor air runs roughly 0.4 pCi/L). A Zone 2 rating is a moderate county-wide average, not a guarantee about any one house in Cherokee County — testing is the only way to know an individual home's actual level.

If Cherokee County tests above the action level

For a Cherokee County homeowner, the order is simple: test first, since a kit costs a small fraction of what mitigation would. Only if the result clears 4 pCi/L does a system — typically $800–$2,500, about $1,200 for a common install — become worth pricing out.
