Page County, Compared
Page County radon figures, compared
Calculated by Radon411More than half: 71.7% of the 653 radon tests reported to CDC for Page County over the 2008 to 2017 laboratory totals read at least 4 pCi/L. That places it 21st of 99 Iowa counties with 30 or more tests for the same period. That is 13.2 points above the 58.5% pooled from 99 Iowa counties.
The median result, 7.2 pCi/L, sits above EPA's 4 pCi/L action level, and the top reported result was 53.4 pCi/L. The rest split 14.1% under 2 pCi/L and 14.2% from 2 to 4 (Iowa: 21.8% and 19.7%). Zone 1 on EPA's map (predicted average above 4 pCi/L) and a 71.7% share point the same way here.
No bordering county with a figure for the same period reported a higher share; the closest is Mills County at 70.1%, the lowest Nodaway County, MO at 34.2%. Statewide for the same period, Sioux County reported the highest share (84.2%) and Decatur County the lowest (25.9%).
CDC's ten-year totals for Page County went from 538 tests (2005 to 2014) to 653 (2008 to 2017), the share going from 76.6% to 71.7%.
Nationally, every county with a figure for the same period pools to 35.7%; Page County sits 36.0 points above it. CDC also counts 58 tests taken after mitigation in Page County for the same period: tests in homes where a fix was already in.

The ground under Page County
PredictedUSGS's geologic map puts all of Page County's mapped land in one class: high radon potential. All of it lies in the area the map calls Loess-Covered Drift Plains, 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 |
|---|---|---|---|---|
| Loess-Covered Drift Plains | Pre-Illinoian and Illinoian glacial deposits, and loess. | High | 13 | 99.9% |

Page County beside the ground around it
On high-potential ground Page County is close to Iowa as a whole: 100% of its land against 98.8%. Of the 7 counties that border it, none has as large a share of high-potential ground; Adams County comes nearest at 100%.
