Radon Levels in Pottawatomie County, Oklahoma

EPA Zone 3: lower predicted potential

is EPA's lowest class, and its forecast for Pottawatomie 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.

Measured: tests reported to CDC

Radon tests reported for Pottawatomie County, 2008 to 2017, laboratory

CDC holds 9 reported tests for Pottawatomie County over the 2008 to 2017 laboratory totals, with a median of 0.1 pCi/L: too few to describe a county (Radon411 reads a share from 30 tests up). Pottawatomie County beside the counties around it is how this page reads it.

What these figures count

Only 9 tests were reported to CDC for Pottawatomie County over 2008 to 2017 (laboratory totals), and tests are often run on homes being sold or already suspected of a problem: so few describe neither the county nor this house.

Measured: CDC tracking data. Figure above: 2008 to 2017, laboratory. Measured data period: 2005 to 2017 (every CDC figure on file).

Pottawatomie County, Compared

Pottawatomie County radon figures, compared

Calculated by Radon411

CDC's largest figure for Pottawatomie County rests on 11 tests over the 2007 to 2016 laboratory totals, 1 of them at or above 4 pCi/L, so each test moves its share by 9.1 points and no rank or comparison is drawn from it. Results reached as high as 9.4 pCi/L, with a middle value of 0.1 pCi/L.

Oklahoma County, the one bordering county with a figure over the 2006 to 2015 laboratory totals, reported 8.9% of its tests at or above 4 pCi/L. Farther out, Tulsa County (85 miles away) at 6.0%, Washington County (119 miles away) at 11.3% and Cherokee County (120 miles away) at 32.0% have figures too. Pooled across 53 Oklahoma counties, 12.6% of reported tests reached that level; across every county in the country with a figure, 36.3%.

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 Pottawatomie 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.

Pottawatomie County, Cities and towns

Cities and towns in Pottawatomie County

The Census Bureau estimates 75,102 residents in Pottawatomie County for July 1, 2025, 2,562 more than in 2020 (+3.5%). That works out to 95 people per square mile of land. Oklahoma City, the largest place on its list (719,849 residents in all), extends beyond Pottawatomie County, so no share of the total is worked out for it.
