Predicted: EPA radon zone

EPA Zone 2: moderate predicted potential

Crawford 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.

Crawford County radon figures, compared

Calculated by Radon411

Crawford County reports fewer high tests than Kansas overall. 5.9% of its 34 tests in 2022 were at or above 4 pCi/L. That is 26.1 points below the 32.0% pooled from 96 Kansas counties.

Ordered from highest share down, it comes 38th of 38 Kansas counties with 30 or more tests for the same period. Nationally, every county with a figure for the same period pools to 23.9%; Crawford County sits 18.0 points below it.

The reported tests do not follow EPA's Zone 2 label for Crawford County (predicted average between 2 and 4 pCi/L): 5.9% of them reached 4 pCi/L, fewer than that label suggests.

Half the tests came in under 0.8 pCi/L and half over it; the single highest reached 16.0 pCi/L. The rest split 73.5% under 2 pCi/L and 20.6% from 2 to 4 (Kansas: 45.8% and 22.1%). Year by year, 2016 opened at 26.5% and 2022 closed at 5.9% (down 20.6 points), with 2021 the high at 35.3%.

The busiest year on file was 2021, with 102 tests reported; the quietest, 2020, had 21.

Share of reported tests at or above 4 pCi/L by year, Crawford County against Kansas2016 to 2022, years with 30 or more tests: Crawford County 26.5% to 5.9%, the state's pooled share 32.0% in 2022.
