McIntosh County, Compared
McIntosh County radon figures, compared
Calculated by Radon411More than half: 71.9% of the 32 radon tests reported to CDC for McIntosh County over the 2008 to 2017 laboratory totals read at least 4 pCi/L. That places it 8th of 29 North Dakota counties with 30 or more tests for the same period. That is 12.6 points above the 59.3% pooled from 53 North Dakota counties.
The median result, 7.0 pCi/L, sits above EPA's 4 pCi/L action level, and the top reported result was 55.8 pCi/L. The rest split 9.4% under 2 pCi/L and 18.8% from 2 to 4 (North Dakota: 18.3% and 22.4%). Zone 1 on EPA's map (predicted average above 4 pCi/L) and a 71.9% share point the same way here.
No bordering county with a figure for the same period reported a higher share; the closest is LaMoure County at 70.5%, the lowest Dickey County at 67.1%. Statewide for the same period, Pembina County reported the highest share (82.5%) and Williams County the lowest (33.8%).
CDC's ten-year totals for McIntosh County went from 38 tests (2005 to 2014) to 32 (2008 to 2017), the share going from 68.4% to 71.9%.
Nationally, every county with a figure for the same period pools to 35.7%; McIntosh County sits 36.2 points above it.

McIntosh County, Geology
The ground under McIntosh County
PredictedUSGS's geologic map puts all of McIntosh County's mapped land in one class: high radon potential. All of it lies in the area the map calls Great Plains (Glaciated), 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 |
|---|---|---|---|---|
| Great Plains (Glaciated) | Glacial deposits derived from Cretaceous shales containing higher than average amounts of uranium. | High | 13 | 99.8% |

McIntosh County beside the ground around it
On high-potential ground McIntosh County is close to North Dakota as a whole: 100% of its land against 98.9%. Of the 6 counties that border it, none has as large a share of high-potential ground; Dickey County comes nearest at 100%.
