Predicted (model estimate). The pCi/L figures on this page are long-term area averages from a peer-reviewed national model built on millions of real radon tests (2001-2021). They describe the typical home in this area - not your home, which can be several times higher or lower. The EPA radon zone is a separate, 1993 county-level classification. How the numbers work.

How 28352 compares

Within Scotland County, ZIP 28352 ranks #3 of 5 ZIPs by predicted basement level; the county average is 1.4 pCi/L and its ZIPs run from 1.4 to 1.5. The county is EPA Radon Zone 3. About 25,641 people lived in this ZIP at the 2010 Census.

Both basement (1.4) and upstairs (0.7) predictions are under 2 pCi/L. That is reassuring for the area, but the model's own uncertainty (± 0.06) and house-to-house variation mean a test is still the only way to know your home.
