Radon tests reported for Rush County, 2008 to 2017, laboratory
CDC holds 17 reported tests for Rush County over the 2008 to 2017 laboratory totals, with a median of 3.9 pCi/L: too few to describe a county (Radon411 reads a share from 30 tests up). Rush County beside the counties around it is how this page reads it.
What these figures count
Only 17 tests were reported to CDC for Rush 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).
Rush County, Compared
Rush County radon figures, compared
Calculated by Radon411CDC's largest figure for Rush County rests on 17 tests over the 2008 to 2017 laboratory totals, 8 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 80.1 pCi/L, with a middle value of 3.9 pCi/L.
Of the counties bordering it, 5 have a figure over the 2008 to 2017 laboratory totals: Henry County reported the largest share at or above 4 pCi/L, 50.5%, and Franklin County the smallest, 28.0%, with Shelby County at 50.0%, Hancock County at 33.9% and Decatur County at 33.3% between. Farther out, Wayne County (30 miles away) at 56.4%, Johnson County (35 miles away) at 39.4% and Bartholomew County (37 miles away) at 48.7% 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 Rush 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 high radon potential.
Pooled shares: Radon411's sum of CDC's county counts for one period.
Rush County, Geology
The ground under Rush County
PredictedUSGS's geologic map puts all of Rush County's mapped land in one class: high radon potential. All of it lies in the area the map calls Huron-Erie Lobe, to which USGS gives a radon index of 13, in the high band (12 to 17).
| 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 | 100% |

Rush County beside the ground around it
Rush County has more high-potential ground than Indiana as a whole: 100% of its land against 56.6%. Of the 6 counties that border it, none has as large a share of high-potential ground; Hancock County comes nearest at 100%.

Rush County, Cities and towns
Cities and towns in Rush County
Rush County's population has barely moved since 2020: 16,767 residents on July 1, 2025 against 16,765 then, by the Census Bureau's estimates. That works out to 41 people per square mile of land. Its largest town, Rushville, has 6,171 residents, 36.8% of the total. Reported testing is thin here: 17 tests over 2008 to 2017, or 1.0 for every 1,000 residents (2025 estimate), where Indiana as a whole comes to 6.2.
From Rushville to Glenwood, CDC publishes no figure by town: each reads Rush County's.

| Rushville | 6,171 | −0.3% | 36.8% |
| Carthage | 920 | +0.2% | 5.5% |
