Is radon high in Becker County, Minnesota?

Moderate. The model predicts a long-term basement average of 3.0 pCi/L in Becker County (about 1.7× the US average of 1.8 and about 1.2× the Minnesota average of 2.4). That is in the 2-4 pCi/L range where the EPA recommends considering mitigation. Ranked 51 of 87 Minnesota counties.

Should I test for radon in Becker County?

Yes, soon. With a predicted average of 3.0 pCi/L, many homes in Becker County will test above the 4 pCi/L action level. Use a short-term kit first; if it reads 2 or higher, confirm with a long-term test or continuous monitor before deciding on mitigation.

What does EPA Radon Zone 1 mean for Becker County?

Zone 1 - highest potential (predicted average > 4 pCi/L). The zone map dates from 1993 and classifies whole counties. The newer model's predicted average of 3.0 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.

How much does radon mitigation cost in Becker County?

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

Predicted long-term basement average of 3.0 pCi/L (model estimate) across 9 ZIP codes - about 1.7× the US average of 1.8, about 1.2× the Minnesota average of 2.4. Ranked #51 of 87 Minnesota counties.

Test Becker County, MN - the EPA says "consider fixing" in this range

The predicted basement average here is 3.0 pCi/L, in the 2-4 pCi/L band where the EPA recommends considering mitigation. Plenty of individual homes in a moderate area test above 4. Start with a short-term test; if it comes back at 2 or higher, follow up with a long-term test or a continuous monitor.

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 Minnesota test results are shown separately and labeled as such. How the numbers work.

Measured tests in Becker County (Minnesota Dept. of Health, 2016-2025)

Actual results from voluntary home tests, separate from the model above. Measured averages usually run higher than the model because tests skew toward basements and worried homeowners.

Mean: 5.1 pCi/L
Median: 4.0 pCi/L
Tests ≥ 4 pCi/L: 54.3%
Tests per year: 60

What this means for Becker

The typical Becker County home is predicted in the 2-4 pCi/L band. The EPA's guidance for this range is to consider fixing, because there is no known safe level and roughly one home in several in a moderate area will test above 4.

Note that the EPA classifies Becker County as Zone 1 while the newer model predicts 3.0 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 Minnesota counties: Le Sueur County (3.1), Wilkin County (3.1), Pope County (3.1), Otter Tail County (3.1). The state's highest is Rock County at 4.7 pCi/L.
