Radon Levels in McIntosh County, Oklahoma

EPA Zone 3: lower predicted potential

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

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

CDC holds 2 reported tests for McIntosh 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). McIntosh County beside the counties around it is how this page reads it.

What these figures count

Only 2 tests were reported to CDC for McIntosh 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).

McIntosh County, Compared

McIntosh County radon figures, compared

Calculated by Radon411

CDC's largest figure for McIntosh County rests on 2 tests over the 2008 to 2017 laboratory totals, 0 of them at or above 4 pCi/L, so each test moves its share by 50.0 points and no rank or comparison is drawn from it. Results reached as high as 2.5 pCi/L, with a middle value of 1.3 pCi/L.

The nearest counties with a figure are Cherokee County (53 miles away) at 32.0%, Tulsa County (54 miles away) at 6.0% and Delaware County (86 miles away) at 44.7%. 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 McIntosh 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.
