Is radon high in Buffalo, New York?

Low. Averaging the model's ZIP-code predictions across Buffalo (weighted by how much of the city each ZIP covers) gives a long-term basement mean of 0.7 pCi/L - about 64% below the US average of 1.8 and about 51% below the New York average of 1.4. That is below the EPA's 2 pCi/L "consider fixing" threshold, though individual homes still vary. Buffalo ranks 21 of 21 New York cities on this site.

What do actual radon tests show around Buffalo?

New York State Department of Health publishes results for Erie County (not the city alone) covering 1987-2025 (9,438 tests): an average of 4.9 pCi/L, 21.4% of results at or above the 4 pCi/L action level. These are voluntary home tests, so they skew toward basements and toward homes where radon was suspected; the model's predicted basement average for Buffalo is 0.7 pCi/L.

Which Buffalo ZIP codes have the highest radon?

Predictions for the 17 modeled ZIP codes in Buffalo range from 0.3 to 1.2 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 Buffalo?

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

What does EPA Radon Zone 1 mean for Buffalo?

Buffalo sits mainly in Erie County, which the EPA classifies as Zone 1 - highest potential (predicted average > 4 pCi/L). The zone map dates from 1993 and covers whole counties. The newer model's city average of 0.7 pCi/L does not line up with Zone 1, which is common - the EPA itself says high-radon homes exist in every zone. Neither replaces a test of your own home.

Radon levels in Buffalo, New York

LowEPA Zone 1

Predicted long-term basement average of 0.7 pCi/L (model estimate) across the 17 modeled ZIP codes in Buffalo - about 64% below the US average of 1.8, about 51% below the New York average of 1.4. Ranked #21 of 21 New York cities on this site. Most of the city lies in Erie County.

Test Buffalo, NY once anyway - radon varies house to house

The predicted basement average here is 0.7 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. Measured state test results are shown separately below, labeled with their source and years. How the numbers work.

Measured radon tests in Erie County (New York State Department of Health, 1987-2025)

Actual results from home radon tests reported to the state, separate from the model estimate above. Coverage: 1987-2025.

Measured mean: 4.9 pCi/L
Results ≥ 4 pCi/L: 21.4%
Basement tests, mean: 5.1 pCi/L
First-floor tests, mean: 3.4 pCi/L
Sample: 9,438 tests

Figure	Model (predicted)	State tests (measured)
Mean, pCi/L	1.2 basement	4.9 (5.1 basement)
Share ≥ 4 pCi/L	not a model output	21.4%

The measured mean runs 3.7 pCi/L above the model because state test data is voluntary and skews toward basements, winter, and homeowners who already suspected a problem, while the model estimates the long-term average across all homes.

What this means for Buffalo

The typical Buffalo home is predicted below 2 pCi/L, the lowest band. That describes the average house; the ZIP-level predictions inside the city still span 0.3 to 1.2 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 city's land in each ZIP (Census 2020 ZCTA-to-place relationship file). Note that the EPA classifies Erie County as Zone 1 while the newer model predicts 0.7 pCi/L for Buffalo; where they disagree, we grade on the model but show both.

Comparable New York cities: New York (1.1), Cheektowaga (1.1), Albany (1.1), Hempstead (1.2).
