What these figures count
Only 3 tests were reported to CDC for Lincoln Parish over 2021, 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. Figure above: 2021. Measured data period: 2005 to 2021 (every CDC figure on file).
Lincoln Parish, Compared
Lincoln Parish radon figures, compared
Calculated by Radon411Only 0 of 33 radon tests reported for Lincoln Parish in 2019 reached 4 pCi/L (0.0%). The median result, 1.3 pCi/L, sits below 2, well under EPA's 4 pCi/L action level, and the top reported result was 2.5 pCi/L.
The newest figure, in 2021, counts only 3 tests (0.0% at or above 4 pCi/L), too few to compare, so this reading uses the 33-test figure.
Across 23 Louisiana counties pooled together, 2.0% of tests reached that level, so Lincoln Parish runs 2.0 points below its state. Against the national pool of 29.0%, the gap is 29.0 points lower. Its place in the state: 5th of 13 Louisiana counties with 30 or more tests for the same period.
Zone 3 on EPA's map (predicted average under 2 pCi/L) and a 0.0% share point the same way here. Ouachita Parish, the one bordering county with a figure for the same period, reported 0.0%.
Below the action level, 27 tests (81.8%) came in under 2 pCi/L, against 95.6% statewide, and 6 tests (18.2%) fell between 2 and 4, against 2.4% statewide. USGS geology rates 100% of the county's land low radon potential.
The busiest year on file was 2019, with 33 tests reported; the quietest, 2021, had 3.

Lincoln Parish, Geology
The ground under Lincoln Parish
PredictedUSGS's geologic map puts all of Lincoln 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% |

Lincoln Parish beside the ground around it
Neither Lincoln Parish nor Louisiana as a whole has any land USGS rates above low potential. None of the 5 parishes that border it has any moderate-potential ground either.
The map rates the ground, not the air in any home.
