Radon Levels in Lee County, Alabama
EPA puts Lee County in Zone 2, its middle radon zone, and most reported tests there come back low, though 12.3% of 81 (2008 to 2017, laboratory totals) reached 4 pCi/L. Homes with elevated levels occur in all three zones, so only a test measures yours.

Lee County, Compared
Lee County radon figures, compared
Calculated by Radon411Lee County reports fewer high tests than Alabama overall. 12.3% of its 81 tests over the 2008 to 2017 laboratory totals were at or above 4 pCi/L. That is 9.6 points below the 21.9% pooled from 65 Alabama counties.
Ordered from highest share down, it comes 19th of 27 Alabama counties with 30 or more tests for the same period. Nationally, every county with a figure for the same period pools to 35.7%; Lee County sits 23.4 points below it.
Next door, the shares run from 5.7% in Muscogee County, GA to 15.7% in Harris County, GA, with Muscogee County, GA below Lee County. Zone 2 on EPA's map (predicted average between 2 and 4 pCi/L) and a 12.3% share point the same way here.
Half the tests came in under 1.3 pCi/L and half over it; the single highest reached 15.5 pCi/L. The rest split 70.4% under 2 pCi/L and 17.3% from 2 to 4 (Alabama: 54.3% and 23.8%).
CDC's ten-year totals for Lee County went from 110 tests (2005 to 2014) to 81 (2008 to 2017), the share going from 12.7% to 12.3%.

The ground under Lee County
PredictedMost of the ground under Lee County is one class on USGS's geologic map: 82.9% of its land is moderate radon potential, with 17.1% low. The map puts 62.0% of Lee County in the area it calls Southern Piedmont and 20.8% in Inner Coastal Plain, with 2 smaller areas beside them. USGS gives the first a radon index of 9 and the second 10, both in the moderate band (9 to 11).
| Area | The rock, in USGS's words | Potential | Radon index | Share of land |
|---|---|---|---|---|
| Southern Piedmont | Paleozoic carbonate and metamorphic rocks. | Moderate | 9 | 62.0% |
| Inner Coastal Plain | Marly sandy clay, chalk, and glauconitic sands. | Moderate | 10 | 20.8% |
| Inner Piedmont | Amphibolite, ultramafic rocks, gneiss, schist, minor granite. | Low | 7 | 9.0% |
| Little River Thrust Stack | Biotite and amphibolite gneiss, granite gneiss, mica schist. | Low | 7 | 8.0% |
