Radon in Greene County, North Carolina
Last updated
Greene County is one of 61 North Carolina counties (out of 100) that EPA places in Zone 3. 10 ZIP codes reach into the county, 2 of them entirely.
What the zone means for a Greene County home
Zone 3 means EPA predicted a county-wide average below 2 pCi/L. Many Greene County homes will test low, but EPA has found homes above the action level in every Zone 3 county it studied, so a low zone is not a pass.
A short-term test kit costs little and takes two to seven days. If your result is 4 pCi/L or higher, EPA recommends a follow-up test and, if it is confirmed, a mitigation system, which typically uses a pipe and fan to pull soil gas from under the foundation and vent it above the roof. Check a result with the level calculator and plan your next step with the follow-up planner.
