Predicted: EPA radon zone

EPA Zone 2: moderate predicted potential

Pike County is a county: EPA's forecast for it as a whole is an average indoor of 2 to 4 pCi/L (75 to 150 Bq/m³). It describes no single address, and homes above EPA's are found in every zone, this one included.

USGS geologic potential: Moderate across 94% of the county's area

Pike County, Compared

Pike County radon figures, compared

Calculated by Radon411

In Pike County, about 3 in 10 reported tests in 2020 (356 of 1,158) were at or above EPA's action level. Against the national pool of 25.5%, the gap is 5.2 points higher. Across 67 Pennsylvania counties pooled together, 30.3% of tests reached that level, so Pike County runs 0.4 points above its state.

Of 3 neighbours with a figure, none reported a larger share at or above 4 pCi/L; the spread is 24.3% (Sussex County, NJ) to 30.7% (Monroe County). By share, Pike County is 47th of 63 Pennsylvania counties with 30 or more tests for the same period.

Year by year, 2014 opened at 38.2% and 2020 closed at 30.7% (down 7.5 points), with 2014 the high at 38.2%. Half the tests came in under 2.2 pCi/L and half over it; the single highest reached 75.9 pCi/L. Below the action level, 545 tests (47.1%) came in under 2 pCi/L, against 44.3% statewide, and 257 tests (22.2%) fell between 2 and 4, against 25.4% statewide.

Zone 2 on EPA's map (predicted average between 2 and 4 pCi/L) and a 30.7% share point the same way here. USGS geology rates 94% of the county's land moderate radon potential.

The busiest year on file was 2020, with 1,158 tests reported; the quietest, 2014, had 498.

Share of reported tests at or above 4 pCi/L by year, Pike County against Pennsylvania2014 to 2020, years with 30 or more tests: Pike County 38.2% to 30.7%, the state's pooled share 30.3% in 2020.

Pike County, Geology

The ground under Pike County

Predicted

Most of the ground under Pike County is one class on USGS's geologic map: 94.1% of its land is moderate radon potential, with 5.9% high. The map puts 94.0% of Pike County in the area it calls Glaciated Low Plateau East and Pocono Plateau and 5.7% in Appalachian Mountain Section. USGS gives the first a radon index of 10, in the moderate band (9 to 11), and the second 12, in the high band (12 to 17).
