Radon tests reported for Fayette County, 2008 to 2017, laboratory
CDC holds 13 reported tests for Fayette County over the 2008 to 2017 laboratory totals, with a median of 7.9 pCi/L: too few to describe a county (Radon411 reads a share from 30 tests up). Fayette County beside the counties around it is how this page reads it.
What these figures count
Only 13 tests were reported to CDC for Fayette 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).
Fayette County, Compared
Fayette County radon figures, compared
Calculated by Radon411CDC's largest figure for Fayette County rests on 18 tests over the 2007 to 2016 laboratory totals, 14 of them at or above 4 pCi/L, so each test moves its share by 5.6 points and no rank or comparison is drawn from it. Results reached as high as 25.8 pCi/L, with a middle value of 7.7 pCi/L.
Of the counties bordering it, 3 have a figure over the 2008 to 2017 laboratory totals: Wayne County reported the largest share at or above 4 pCi/L, 56.4%, and Franklin County the smallest, 28.0%, with Henry County at 50.5% between. Farther out, Decatur County (29 miles away) at 33.3%, Shelby County (34 miles away) at 50.0% and Hancock County (34 miles away) at 33.9% have figures too. Pooled across 92 Indiana counties, 38.9% of reported tests reached that level; across every county in the country with a figure, 35.7%.
Statewide for the same period, Miami County reported the highest share (63.3%) and Jasper County the lowest (14.1%). EPA's 1993 map puts Fayette County in Zone 1, the map's highest label: a predicted county average above 4 pCi/L. USGS geology rates 93% of the county's land high radon potential.

The ground under Fayette County
PredictedMost of the ground under Fayette County is one class on USGS's geologic map: 92.9% of its land is high radon potential, with 7.1% moderate. The map puts 92.9% of Fayette County in the area it calls Huron-Erie Lobe and 7.1% in Dearborn Upland. USGS gives the first a radon index of 13, in the high band (12 to 17), and the second 10, in the moderate band (9 to 11).
| Area | The rock, in USGS's words | Potential | Radon index | Share of land |
|---|---|---|---|---|
| Huron-Erie Lobe | Calcareous clayey and loamy glacial deposits derived from marine carbonate and clastic sedimentary rocks. | High | 13 | 92.9% |
| Dearborn Upland | Ordovician through Devonian limestone, dolostone, and gray shale, and pre-Wisconsinan glacial deposits. | Moderate | 10 | 7.1% |
