Pike County radon figures, compared
Calculated by Radon411Pike County is in a state CDC's county radon counts do not reach: no Mississippi county has a figure, while 2,669 counties elsewhere do over the 2006 to 2015 laboratory totals. Across every county in the country with a figure (2,669), 36.3% of reported tests reached that level; no Mississippi county contributes to that pool.
Tangipahoa Parish, LA, the one bordering county with a figure over the 2006 to 2015 laboratory totals, reported 0.0% of its tests at or above 4 pCi/L. Farther out, East Baton Rouge Parish, LA (60 miles away) at 0.0%, Jefferson Parish, LA (97 miles away) at 1.5% and Mobile County, AL (133 miles away) at 4.4% have figures too.
EPA's 1993 map puts Pike 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.

Pike County, Geology
The ground under Pike County
PredictedUSGS's geologic map puts all of Pike County's mapped land in one class: low radon potential. All of it lies in the area the map calls Pine Hills, to which USGS gives a radon index of 6, in the low band (5 to 8).
| Area | The rock, in USGS's words | Potential | Radon index | Share of land |
|---|---|---|---|---|
| Pine Hills | Sand, sandstone, bentonitic clay, quartzite, gravel, tuff, and siltstone. | Low | 6 | 99.8% |

Pike County beside the ground around it
Across Mississippi 0.1% of the land is rated high; none of Pike County's is. None of the 5 counties that border it has any moderate-potential ground either.
The map rates the ground, not the air in any home.
