Pike County, Compared
Pike County radon figures, compared
Calculated by Radon411More than half: 56.1% of the 57 radon tests reported to CDC for Pike County over the 2008 to 2017 laboratory totals read at least 4 pCi/L. That places it 40th of 79 Ohio counties with 30 or more tests for the same period. That is 3.8 points above the 52.3% pooled from 88 Ohio counties.
The median result, 4.5 pCi/L, sits above EPA's 4 pCi/L action level, and the top reported result was 71.7 pCi/L. The rest split 21.1% under 2 pCi/L and 22.8% from 2 to 4 (Ohio: 23.1% and 24.6%). Zone 1 on EPA's map (predicted average above 4 pCi/L) and a 56.1% share point the same way here.
2 of its 4 bordering counties with figures ran higher, led by Ross County at 67.1%; Scioto County reported 37.0%. Statewide for the same period, Pickaway County reported the highest share (81.4%) and Cuyahoga County the lowest (21.7%).
CDC's ten-year totals for Pike County went from 190 tests (2005 to 2014) to 57 (2008 to 2017), the share going from 45.3% to 56.1%.
Nationally, every county with a figure for the same period pools to 35.7%; Pike County sits 20.4 points above it.

The ground under Pike County
PredictedMost of the ground under Pike County is one class on USGS's geologic map: 98.5% of its land is high radon potential, with 1.5% moderate. The map puts 62.5% of Pike County in the area it calls Mississippian Limestone and 36.0% in Ohio Shale, with one smaller area beside them. USGS gives both a radon index of 14, in the high band (12 to 17).
| Area | The rock, in USGS's words | Potential | Radon index | Share of land |
|---|---|---|---|---|
| Mississippian Limestone | Mississippian limestone exhibiting high gamma radioactivity. | High | 14 | 62.5% |
| Ohio Shale | Devonian-Mississippian black shale (includes some Ordovician limestone) | High | 14 | 36.0% |
| Unglaciated Plateau | Mississippian through Permian limestone, dolomite, and shale. | Moderate | 11 | 1.5% |
