What EPA's radon map says about Cherokee County

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. Rank it against the rest of the country and Cherokee County lands in the 63rd percentile for radon potential.

How Cherokee County compares

About 293,513 people live in Cherokee County, Georgia, spread over 420.956 square miles. Averaged across its land area, Cherokee County runs about 697 people per square mile.

Why the zone isn't the answer by itself

Neither at the 4 pCi/L action level nor down at the roughly 1.3 pCi/L national indoor norm, Cherokee County's Zone 2 prediction lands in the gap between the two. Nothing about a Zone 2 label lowers the case for testing in Cherokee County — EPA recommends it in every zone, moderate included.
