Radon tests reported for Mingo County, 2008 to 2017, laboratory
CDC holds 5 reported tests for Mingo County over the 2008 to 2017 laboratory totals, with a median of 1.0 pCi/L: too few to describe a county (Radon411 reads a share from 30 tests up). Mingo County beside the counties around it is how this page reads it.
What these figures count
Only 5 tests were reported to CDC for Mingo 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).
Mingo County, Compared
Mingo County radon figures, compared
Calculated by Radon411CDC's largest figure for Mingo County rests on 5 tests over the 2008 to 2017 laboratory totals, 0 of them at or above 4 pCi/L, so each test moves its share by 20.0 points and no rank or comparison is drawn from it. Results reached as high as 2.1 pCi/L, with a middle value of 1.0 pCi/L.
Pike County, KY, the one bordering county with a figure over the 2008 to 2017 laboratory totals, reported 17.1% of its tests at or above 4 pCi/L. Farther out, Cabell County (48 miles away) at 16.6%, Raleigh County (49 miles away) at 16.7% and Kanawha County (54 miles away) at 20.6% have figures too. Pooled across 55 West Virginia counties, 37.5% of reported tests reached that level; across every county in the country with a figure, 35.7%.
Statewide for the same period, Morgan County reported the highest share (58.1%) and Grant County the lowest (9.8%). EPA's 1993 map puts Mingo County in Zone 3, its lowest label: a predicted county average under 2 pCi/L. USGS geology rates 99% of the county's land low radon potential.
