Nevada County, Compared
Nevada County radon figures, compared
Calculated by Radon411Nevada County has no radon test figure of its own from CDC, whose counts over the 2007 to 2016 laboratory totals name 60 other Arkansas counties and leave it out. Pooled across 60 Arkansas counties, 22.7% of reported tests reached that level; across every county in the country with a figure, 35.8%.
The nearest counties with a figure are Garland County (64 miles away) at 45.8%, Saline County (77 miles away) at 31.9% and Pulaski County (95 miles away) at 6.8%. Statewide for the same period, Garland County reported the highest share (45.8%) and Pulaski County the lowest (6.8%).
EPA's 1993 map puts Nevada County in Zone 3, its lowest label: a predicted county average under 2 pCi/L. USGS geology rates 100% of the county's land low radon potential.
Pooled shares: Radon411's sum of CDC's county counts for one period.
Nevada County, Geology
The ground under Nevada County
PredictedUSGS's geologic map puts all of Nevada County's mapped land in one class: low radon potential. All of it lies in the area the map calls West Gulf Coastal Plain, to which USGS gives a radon index of 7, in the low band (5 to 8).
| Area | The rock, in USGS's words | Potential | Radon index | Share of land |
|---|---|---|---|---|
| West Gulf Coastal Plain | Glauconitic, phosphatic, and carbonaceous sediments. | Low | 7 | 100% |

Nevada County beside the ground around it
Across Arkansas 21.3% of the land is rated moderate; none of Nevada County's is. Of the 6 counties that border it, 2 have more moderate-potential ground, Pike County the most at 8.0%.
