Locations and reports

Measured: tests reported to CDC
CDC holds 10 reported tests for Morgan County over the 2008 to 2017 laboratory totals, with a median of 3.3 pCi/L: too few to describe a county (Radon411 reads a share from 30 tests up). Morgan County beside the counties around it is how this page reads it.
Only 10 tests were reported to CDC for Morgan 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).
Morgan County, Compared
CDC's largest figure for Morgan County rests on 11 tests over the 2006 to 2015 laboratory totals, 3 of them at or above 4 pCi/L, so each test moves its share by 9.1 points and no rank or comparison is drawn from it. Results reached as high as 9.5 pCi/L, with a middle value of 3.4 pCi/L.
Of the counties bordering it, 5 have a figure over the 2008 to 2017 laboratory totals: Muskingum County reported the largest share at or above 4 pCi/L, 56.3%, and Noble County the smallest, 31.0%, with Perry County at 48.9%, Washington County at 38.1% and Athens County at 38.1% between. Farther out, Hocking County (35 miles away) at 53.3%, Guernsey County (35 miles away) at 44.4% and Monroe County (42 miles away) at 58.3% have figures too. Pooled across 88 Ohio counties, 52.3% of reported tests reached that level; across every county in the country with a figure, 35.7%.
Statewide for the same period, Pickaway County reported the highest share (81.4%) and Cuyahoga County the lowest (21.7%). EPA's 1993 map puts Morgan County in Zone 2, its middle label: a predicted county average between 2 and 4 pCi/L. USGS geology rates 100% of the county's land moderate radon potential.

Morgan County, Geology
USGS's geologic map puts all of Morgan County's mapped land in one class: moderate radon potential. All of it lies in the area the map calls Unglaciated Plateau, to which USGS gives a radon index of 11, in the moderate band (9 to 11).
| Area | The rock, in USGS's words | Potential | Radon index | Share of land |
|---|---|---|---|---|
| Unglaciated Plateau | Mississippian through Permian limestone, dolomite, and shale. | Moderate | 11 | 100% |

Across Ohio 62.8% of the land is rated high; none of Morgan County's is. Of the 5 counties that border it, 2 have more high-potential ground, Muskingum County the most at 71.5%.
The map rates the ground, not the air in any home.
