Radon tests reported for Scott County, 2008 to 2017, laboratory
CDC holds 17 reported tests for Scott County over the 2008 to 2017 laboratory totals, with a median of 2.0 pCi/L: too few to describe a county (Radon411 reads a share from 30 tests up). Scott County beside the counties around it is how this page reads it.
What these figures count
Only 17 tests were reported to CDC for Scott 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).
Scott County, Compared
Scott County radon figures, compared
Calculated by Radon411CDC's largest figure for Scott County rests on 17 tests over the 2008 to 2017 laboratory totals, 6 of them at or above 4 pCi/L, so each test moves its share by 5.9 points and no rank or comparison is drawn from it. Results reached as high as 9.3 pCi/L, with a middle value of 2.0 pCi/L.
Of the counties bordering it, 5 have a figure over the 2008 to 2017 laboratory totals: Clark County reported the largest share at or above 4 pCi/L, 47.7%, and Jackson County the smallest, 27.3%, with Jefferson County at 45.8%, Washington County at 42.1% and Jennings County at 35.1% between. Farther out, Floyd County (27 miles away) at 42.4%, Bartholomew County (37 miles away) at 48.7% and Ripley County (39 miles away) at 35.3% 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 Scott County in Zone 1, the map's highest label: a predicted county average above 4 pCi/L. USGS geology rates 62% of the county's land high radon potential.

Scott County, Geology
The ground under Scott County
PredictedUSGS's geologic map splits Scott County: 61.6% of its land is high radon potential and 38.4% moderate. The map puts 61.6% of Scott County in the area it calls New Albany Shale and 38.4% in Crawford Upland/Mitchell Plain/Norman Upland. USGS gives the first a radon index of 12, in the high band (12 to 17), and the second 11, in the moderate band (9 to 11).
| Area | The rock, in USGS's words | Potential | Radon index | Share of land |
|---|---|---|---|---|
| New Albany Shale | New Albany black shale. | High | 12 | 61.6% |
| Crawford Upland/Mitchell Plain/Norman Upland | Unglaciated, underlain by karsted Mississippian carbonate rocks. | Moderate | 11 | 38.4% |
