Radon tests reported for Summers County, 2008 to 2017, laboratory
CDC holds 15 reported tests for Summers County over the 2008 to 2017 laboratory totals, with a median of 1.5 pCi/L: too few to describe a county (Radon411 reads a share from 30 tests up). Summers County beside the counties around it is how this page reads it.
What these figures count
Only 15 tests were reported to CDC for Summers 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).
Summers County, Compared
Summers County radon figures, compared
Calculated by Radon411CDC's largest figure for Summers County rests on 15 tests over the 2008 to 2017 laboratory totals, 2 of them at or above 4 pCi/L, so each test moves its share by 6.7 points and no rank or comparison is drawn from it. Results reached as high as 12.7 pCi/L, with a middle value of 1.5 pCi/L.
Of the counties bordering it, 4 have a figure over the 2008 to 2017 laboratory totals: Giles County, VA reported the largest share at or above 4 pCi/L, 56.9%, and Raleigh County the smallest, 16.7%, with Greenbrier County at 52.3% and Mercer County at 33.7% between. Farther out, Kanawha County (59 miles away) at 20.6%, Putnam County (82 miles away) at 23.1% and Cabell County (92 miles away) at 16.6% 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 Summers County in Zone 1, the map's highest label: a predicted county average above 4 pCi/L. USGS geology rates 100% of the county's land moderate radon potential.
