Bedford County, At a glance

Predicted: EPA radon zone

EPA Zone 1: highest predicted potential

EPA puts all of Bedford County in and predicts an average indoor of greater than 4 pCi/L (greater than 150 Bq/m³) across the county. That is one forecast for the whole county, not a reading of any address in it; homes above EPA's turn up in all three zones.

Bedford County, Compared

Bedford County radon figures, compared

Calculated by Radon411

In Bedford County, about 5 in 10 reported tests in 2020 (33 of 69) were at or above EPA's action level. Against the national pool of 25.5%, the gap is 22.3 points higher. Across 67 Pennsylvania counties pooled together, 30.3% of tests reached that level, so Bedford County runs 17.5 points above its state.

Of 4 neighbours with a figure, 1 reported a larger share at or above 4 pCi/L and 3 a smaller one; the spread is 42.0% (Blair County) to 54.0% (Huntingdon County). By share, Bedford County is 8th of 63 Pennsylvania counties with 30 or more tests for the same period.

Year by year, 2014 opened at 56.3% and 2020 closed at 47.8% (down 8.5 points), with 2015 the high at 61.3%. Half the tests came in under 3.8 pCi/L and half over it; the single highest reached 64.4 pCi/L. Below the action level, 19 tests (27.5%) came in under 2 pCi/L, against 44.3% statewide, and 17 tests (24.6%) fell between 2 and 4, against 25.4% statewide.

Zone 1 on EPA's map (predicted average above 4 pCi/L) and a 47.8% share point the same way here. USGS geology rates 98% of the county's land high radon potential.

The busiest year on file was 2016, with 216 tests reported; the quietest, 2020, had 69.

Share of reported tests at or above 4 pCi/L by year, Bedford County against Pennsylvania2014 to 2020, years with 30 or more tests: Bedford County 56.3% to 47.8%, the state's pooled share 30.3% in 2020.

Cities and towns in Bedford County

Bedford County's population has barely moved since 2020: 47,480 residents on July 1, 2025 against 47,569 then, by the Census Bureau's estimates. That works out to 47 people per square mile of land.
