Radon Levels in Muskogee County, Oklahoma

EPA puts Muskogee County in Zone 3, its lowest radon zone, and only 17 radon tests from it are on file with CDC (2008 to 2017, laboratory totals). Homes with elevated levels occur in all three zones, so only a test measures yours.

Predicted: EPA radon zone

EPA Zone 3: lower predicted potential

is EPA's lowest class, and its forecast for Muskogee 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 Muskogee County, 2008 to 2017, laboratory

CDC holds 17 reported tests for Muskogee County over the 2008 to 2017 laboratory totals, with a median of 1.3 pCi/L: too few to describe a county (Radon411 reads a share from 30 tests up). Muskogee County beside the counties around it is how this page reads it.

What these figures count

Only 17 tests were reported to CDC for Muskogee 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).

Muskogee County, Compared

Muskogee County radon figures, compared

Calculated by Radon411

CDC's largest figure for Muskogee County rests on 17 tests over the 2008 to 2017 laboratory totals, 1 of them at or above 4 pCi/L, so each test moves its share by 5.9 points and no rank or comparison is drawn from it. Results reached as high as 7.4 pCi/L, with a middle value of 1.3 pCi/L.

Cherokee County, the one bordering county with a figure over the 2006 to 2015 laboratory totals, reported 32.0% of its tests at or above 4 pCi/L. Farther out, Tulsa County (47 miles away) at 6.0%, Delaware County (63 miles away) at 44.7% and Washington County (81 miles away) at 11.3% 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 Muskogee County in Zone 3, its lowest label: a predicted county average under 2 pCi/L. USGS geology rates 97% of the county's land low radon potential.

Muskogee County, Geology

The ground under Muskogee County

Predicted

Most of the ground under Muskogee County is one class on USGS's geologic map: 97.3% of its land is low radon potential, with 2.7% moderate. The map puts 63.4% of Muskogee County in the area it calls Central Oklahoma Plains and Hills and 33.9% in Lower Arkansas River Valley, with one smaller area beside them. USGS gives the first a radon index of 7 and the second 8, both in the low band (5 to 8).
