Predicted: EPA radon zone

EPA Zone 3: lower predicted potential

is EPA's lowest class, and its forecast for Pawnee County as a whole is an average indoor of less than 2 pCi/L (less than 75 Bq/m³). A low zone clears no address in it: homes above EPA's turn up in all three zones.

Pawnee County, Compared

Pawnee County radon figures, compared

Calculated by Radon411

Pawnee County has no radon test figure of its own from CDC, whose counts over the 2006 to 2015 laboratory totals name 53 other Oklahoma counties and leave it out. Pooled across 53 Oklahoma counties, 12.6% of reported tests reached that level; across every county in the country with a figure, 36.3%.

Tulsa County, the one bordering county with a figure over the 2006 to 2015 laboratory totals, reported 6.0% of its tests at or above 4 pCi/L. Farther out, Washington County (52 miles away) at 11.3%, Oklahoma County (66 miles away) at 8.9% and Cherokee County (99 miles away) at 32.0% have figures too. Statewide for the same period, Delaware County reported the highest share (44.7%) and Tulsa County the lowest (6.0%).

EPA's 1993 map puts Pawnee County in Zone 3, its lowest label: a predicted county average under 2 pCi/L. USGS geology rates 100% of the county's land low radon potential.
