Radon tests reported for Bienville Parish, 2016
CDC holds 3 reported tests for Bienville Parish in 2016, with a median of 0.9 pCi/L: too few to describe a county (Radon411 reads a share from 30 tests up). Bienville Parish beside the counties around it is how this page reads it.
What these figures count
Only 3 tests were reported to CDC for Bienville Parish over 2016, and tests are often run on homes being sold or already suspected of a problem: so few describe neither the parish nor this house.
Measured: CDC tracking data. Measured data period: 2016.
Bienville Parish, Compared
Bienville Parish radon figures, compared
Calculated by Radon411CDC's largest figure for Bienville Parish rests on 3 tests in 2016, 0 of them at or above 4 pCi/L, so each test moves its share by 33.3 points and no rank or comparison is drawn from it. Results reached as high as 0.9 pCi/L, with a middle value of 0.9 pCi/L.
The nearest counties with a figure are Calcasieu Parish (147 miles away) at 0.0%, East Baton Rouge Parish (170 miles away) at 0.0% and Tangipahoa Parish (196 miles away) at 0.0%.

Bienville Parish, Geology
The ground under Bienville Parish
PredictedUSGS's geologic map puts all of Bienville Parish's mapped land in one class: low radon potential. All of it lies in the area the map calls Old Uplands, 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 |
|---|---|---|---|---|
| Old Uplands | Clays, silts, sands, and ironstone. | Low | 7 | 100% |

Bienville Parish beside the ground around it
Neither Bienville Parish nor Louisiana as a whole has any land USGS rates above low potential. None of the 8 parishes that border it has any moderate-potential ground either.
