Is radon high in Glen Burnie, Maryland?

Low. Averaging the model's ZIP-code predictions across Glen Burnie (weighted by how much of the city each ZIP covers) gives a long-term basement mean of 1.1 pCi/L - about 40% below the US average of 1.8 and about 16% below the Maryland average of 1.3. That is below the EPA's 2 pCi/L "consider fixing" threshold, though individual homes still vary. Glen Burnie ranks 15 of 20 Maryland cities on this site.

Which Glen Burnie ZIP codes have the highest radon?

Predictions for the 5 modeled ZIP codes in Glen Burnie range from 1.0 to 1.4 pCi/L in the basement. 0% of them are predicted at or above 4 pCi/L and 0% at or above 2. The city is fairly uniform, so the city-wide number is a reasonable guide for any neighborhood.

Should I test for radon in Glen Burnie?

Yes, once. The EPA recommends testing every home regardless of area. A short-term kit costs little and settles the question for your house; Glen Burnie's low predicted average describes the typical home, not yours.

What does EPA Radon Zone 2 mean for Glen Burnie?

Glen Burnie sits mainly in Anne Arundel County, which the EPA classifies as Zone 2 - moderate potential (2-4 pCi/L). The zone map dates from 1993 and covers whole counties. The newer model's city average of 1.1 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.

LowEPA Zone 2

Predicted long-term basement average of 1.1 pCi/L (model estimate) across the 5 modeled ZIP codes in Glen Burnie - about 40% below the US average of 1.8, about 16% below the Maryland average of 1.3.

Test Glen Burnie, MD once anyway - radon varies house to house

The predicted basement average here is 1.1 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 Glen Burnie

The typical Glen Burnie home is predicted below 2 pCi/L, the lowest band. That describes the average house; the ZIP-level predictions inside the city still span 1.0 to 1.4 pCi/L.

The city figure is not a separate estimate: it is the mean of the model's ZIP-code predictions, weighted by the share of the census-designated place's land in each ZIP (Census 2020 ZCTA-to-place relationship file). Note that the EPA classifies Anne Arundel County as Zone 2 while the newer model predicts 1.1 pCi/L for Glen Burnie; where they disagree, we grade on the model but show both.
