Radon Levels in Pitt County, North Carolina

EPA puts Pitt County in Zone 3, its lowest radon zone, and most reported tests there come back low, though 0.9% of 116 (2022) reached 4 pCi/L. Homes with elevated levels occur in all three zones, so only a test measures yours.

Pitt County, Compared

Pitt County radon figures, compared

Calculated by Radon411

Only 1 of 116 radon tests reported for Pitt County in 2022 reached 4 pCi/L (0.9%). The median result, 1.0 pCi/L, sits below 2, well under EPA's 4 pCi/L action level, and the top reported result was 4.0 pCi/L.

Across 57 North Carolina counties pooled together, 10.7% of tests reached that level, so Pitt County runs 9.8 points below its state. Against the national pool of 23.9%, the gap is 23.0 points lower. Its place in the state: 4th of 4 North Carolina counties with 30 or more tests for the same period.

Zone 3 on EPA's map (predicted average under 2 pCi/L) and a 0.9% share point the same way here.

Below the action level, 91 tests (78.4%) came in under 2 pCi/L, against 70.8% statewide, and 24 tests (20.7%) fell between 2 and 4, against 18.5% statewide. USGS geology rates 100% of the county's land low radon potential.

The busiest year on file was 2022, with 116 tests reported; the quietest, 2014, had 6.
