Dodge County, GA: EPA's radon zone, explained

EPA places Dodge County in Zone 3 - Low Potential — a predicted county-wide average indoor radon level below 2 pCi/L, based on the geology, soil and aerial radioactivity data behind EPA's national map. That puts Dodge County in the 13th percentile nationally for radon potential — higher than 13% of the counties EPA has rated.

Why the zone isn't the answer by itself

Well clear of both the 1.3 pCi/L national indoor average and EPA's 4 pCi/L action level, Dodge County's Zone 3 prediction is the low end of the scale. Even at Zone 3, Dodge County homes are not guaranteed a low reading — zone is a county-wide average, and EPA recommends testing every home regardless of zone.

Testing and mitigation in Dodge County

For a Dodge 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.
