Is radon high in Noxubee County, Mississippi?

Low. The model predicts a long-term basement average of 1.5 pCi/L in Noxubee County (about 16% below the US average of 1.8 and close to the Mississippi average of 1.5). That is below the EPA's 2 pCi/L "consider fixing" threshold, though individual homes still vary. Ranked 32 of 82 Mississippi counties.

Should I test for radon in Noxubee County?

Yes, once. The EPA recommends testing every home regardless of area, and the model's ZIP-level predictions in Noxubee County already range from 1.4 to 1.6 pCi/L. A short-term kit costs little and settles the question for your house.

What does EPA Radon Zone 2 mean for Noxubee County?

Zone 2 - moderate potential (2-4 pCi/L). The zone map dates from 1993 and classifies whole counties. The newer model's predicted average of 1.5 pCi/L does not line up with Zone 2, which is common - the EPA itself says high-radon homes exist in every zone. Neither replaces a test of your own home.

How much does radon mitigation cost in Noxubee County?

A standard active sub-slab depressurization system typically runs $800-$2,500 installed nationally; Mississippi quotes vary with foundation type (slab, crawlspace, basement), home size and local labor.

The predicted basement average here is 1.5 pCi/L, below the EPA's 2 pCi/L "consider fixing" threshold. That's good news for the area - but the EPA still recommends every home be tested, because foundation cracks, soil pockets and ventilation make one house very different from its neighbor. One inexpensive kit settles it.

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.

What this means for Noxubee

The typical Noxubee County home is predicted below 2 pCi/L, the lowest band. That is the best case an area can show - but it describes the average house, and the ZIP-level predictions within the county still span 1.4 to 1.6 pCi/L.

Note that the EPA classifies Noxubee County as Zone 2 while the newer model predicts 1.5 pCi/L. The zone map predates two decades of test data; where they disagree, we grade on the model but show both. County figures weight each ZIP by its 2010 Census population, so they describe where people live rather than empty land.

Comparable Mississippi counties: Lamar County (1.5), Walthall County (1.5), Wayne County (1.5), DeSoto County (1.5). The state's highest is Alcorn County at 1.8 pCi/L.
