Radon tests reported for McCurtain County, 2008 to 2017, laboratory
CDC holds 1 reported test for McCurtain County over the 2008 to 2017 laboratory totals, a result of 1.9 pCi/L: too few to describe a county (Radon411 reads a share from 30 tests up). McCurtain County beside the counties around it is how this page reads it.
What these figures count
Only 1 test was reported to CDC for McCurtain 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. Measured data period: 2008 to 2017.
McCurtain County, Compared
McCurtain County radon figures, compared
Calculated by Radon411CDC's largest figure for McCurtain County rests on 1 test over the 2008 to 2017 laboratory totals, 0 of them at or above 4 pCi/L, so each test moves its share by 100.0 points and no rank or comparison is drawn from it. Results reached as high as 1.9 pCi/L, with a middle value of 1.9 pCi/L.
The nearest counties with a figure are Cherokee County (124 miles away) at 32.0%, Tulsa County (153 miles away) at 6.0% and Delaware County (158 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 McCurtain 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.
