Bottineau County, Compared
Bottineau County radon figures, compared
Calculated by Radon411More than half: 64.0% of the 111 radon tests reported to CDC for Bottineau County over the 2008 to 2017 laboratory totals read at least 4 pCi/L. That places it 14th of 29 North Dakota counties with 30 or more tests for the same period. That is 4.7 points above the 59.3% pooled from 53 North Dakota counties.
The median result, 5.7 pCi/L, sits above EPA's 4 pCi/L action level, and the top reported result was 33.4 pCi/L. The rest split 20.7% under 2 pCi/L and 15.3% 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 64.0% share point the same way here.
Pierce County, the one bordering county with a figure for the same period, reported 48.7%. 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 Bottineau County went from 101 tests (2005 to 2014) to 111 (2008 to 2017), the share going from 67.3% to 64.0%.

The ground under Bottineau County
PredictedUSGS's geologic map puts all of Bottineau County's mapped land in one class: high radon potential. The map puts 64.8% of Bottineau County in the area it calls Glacial Lakes and 35.2% in Great Plains (Glaciated). USGS gives the first a radon index of 14 and the second 13, both in the high band (12 to 17).
| Area | The rock, in USGS's words | Potential | Radon index | Share of land |
|---|---|---|---|---|
| Glacial Lakes | Silt and clay deposits derived from Cretaceous shales containing higher than average amounts of uranium. | High | 14 | 64.8% |
| Great Plains (Glaciated) | Glacial deposits derived from Cretaceous shales containing higher than average amounts of uranium. | High | 13 | 35.2% |
