2022: 57.1%. Across these years the share ran from 0.0% to 57.1%. Each column counts radon tests reported to CDC that year, not homes.
Only 7 tests were reported to CDC for Bourbon County over 2022, and tests are often run on homes being sold or already suspected of a problem: so few describe neither the county nor this house.

Bourbon County, Compared
CDC's largest figure for Bourbon County rests on 27 tests in 2021, 12 of them at or above 4 pCi/L, so each test moves its share by 3.7 points and no rank or comparison is drawn from it. Results reached as high as 16.5 pCi/L, with a middle value of 3.3 pCi/L.
Crawford County, the one bordering county with a figure in 2019, reported 26.0% of its tests at or above 4 pCi/L. Farther out, Miami County (49 miles away) at 35.0%, Franklin County (54 miles away) at 21.2% and Johnson County (71 miles away) at 38.2% have figures too. Pooled across 102 Kansas counties, 33.7% of reported tests reached that level; across every county in the country with a figure, 29.0%.
Statewide for the same period, Jewell County reported the highest share (71.9%) and Reno County the lowest (20.8%). EPA's 1993 map puts Bourbon 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.

Bourbon County, Geology
USGS's geologic map puts all of Bourbon County's mapped land in one class: moderate radon potential. All of it lies in the area the map calls Glaciated Area, to which USGS gives a radon index of 9, in the moderate band (9 to 11).
| Area | The rock, in USGS's words | Potential | Radon index | Share of land |
|---|---|---|---|---|
| Glaciated Area | Glacial till underlain by Pennsylvanian and Permian marine and nonmarine sedimentary shale, sandstone, limestone, coal. | Moderate | 9 | 100% |
Names, descriptions and indexes: U.S. Geological Survey, Geologic Radon Potential Map (2025). Shares: Radon411, from the map cut to the boundary.
Across Kansas 59.9% of the land is rated high; none of Bourbon County's is. Of the 6 counties that border it, none has as large a share of moderate-potential ground; Allen County comes nearest at 100%.
The map rates the ground, not the air in any home.
