What EPA's radon map says about Wilkinson County
Wilkinson County is mapped as Zone 3 - Low Potential by EPA — meaning the county-wide average indoor level is predicted below 2 pCi/L. That puts Wilkinson County in the 6th percentile nationally for radon potential — higher than 6% of the counties EPA has rated.

Zone vs. an actual test
At Zone 3, Wilkinson County's predicted county average is under the national indoor average (~1.3 pCi/L) and well below EPA's 4 pCi/L action level — outdoor air nationally runs about 0.4 pCi/L for comparison. Low doesn't mean zero: EPA's own data shows homes in Zone 3 counties like Wilkinson County testing above the action level often enough that skipping a test isn't the safe assumption.
If Wilkinson County tests above the action level
Mitigation cost doesn't depend on Wilkinson County's zone — it depends on the house's foundation. A typical system runs $800–$2,500 (about $1,200 typical), and testing first is what tells you whether that's needed at all.
