Radon tests reported for Lauderdale County, 2008 to 2017, laboratory
CDC holds 9 reported tests for Lauderdale County over the 2008 to 2017 laboratory totals, with a median of 1.3 pCi/L: too few to describe a county (Radon411 reads a share from 30 tests up). Lauderdale County beside the counties around it is how this page reads it.
What these figures count
Only 9 tests were reported to CDC for Lauderdale County over 2008 to 2017 (laboratory totals), and tests are often run on homes being sold or already suspected of a problem: so few describe neither the county nor this house.
Measured: CDC tracking data. Figure above: 2008 to 2017, laboratory. Measured data period: 2005 to 2017 (every CDC figure on file).
Lauderdale County, Compared
Lauderdale County radon figures, compared
Calculated by Radon411CDC's largest figure for Lauderdale County rests on 9 tests over the 2008 to 2017 laboratory totals, 1 of them at or above 4 pCi/L, so each test moves its share by 11.1 points and no rank or comparison is drawn from it. Results reached as high as 4.1 pCi/L, with a middle value of 1.3 pCi/L.
Tipton County, the one bordering county with a figure over the 2008 to 2017 laboratory totals, reported 4.5% of its tests at or above 4 pCi/L. Farther out, Fayette County (41 miles away) at 11.1%, Gibson County (42 miles away) at 5.3% and Shelby County (42 miles away) at 6.3% have figures too. Pooled across 95 Tennessee counties, 33.3% of reported tests reached that level; across every county in the country with a figure, 35.7%.
Statewide for the same period, Jefferson County reported the highest share (56.8%) and Chester County the lowest (0.0%). EPA's 1993 map puts Lauderdale 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.

Lauderdale County, Geology
The ground under Lauderdale County
PredictedUSGS's geologic map puts all of Lauderdale County's mapped land in one class: low radon potential. The map puts 52.9% of Lauderdale County in the area it calls Loess-Covered Coastal Plain and 46.5% in Mississippi Alluvial Plain, with one smaller area beside them. USGS gives the first a radon index of 8 and the second 7, both in the low band (5 to 8).
| Area | The rock, in USGS's words | Potential | Radon index | Share of land |
|---|---|---|---|---|
| Loess-Covered Coastal Plain | Cretaceous and younger marine and fluvial sand, clay, and marl covered with loess. | Low | 8 | 52.9% |
| Mississippi Alluvial Plain | Alluvial sand, silt, gravel, and clay. | Low | 7 | 46.5% |
| Mississippi Alluvial Plain | Alluvial sand, silt, gravel, and clay. | Low | 8 | 0.6% |
