Woodson County, Compared
CDC's largest figure for Woodson County rests on 2 tests in 2020, 0 of them at or above 4 pCi/L, so each test moves its share by 50.0 points and no rank or comparison is drawn from it. Results reached as high as 3.4 pCi/L, with a middle value of 2.0 pCi/L.
The nearest counties with a figure are Lyon County (45 miles away) at 38.0%, Osage County (53 miles away) at 31.0% and Franklin County (53 miles away) at 21.2%. 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 Woodson 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.

Woodson County, Geology
USGS's geologic map puts all of Woodson 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% |

Across Kansas 59.9% of the land is rated high; none of Woodson 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%.
