Radon tests reported for Wayne County, 2022
CDC holds 9 reported tests for Wayne County in 2022, with a median of 10.2 pCi/L: too few to describe a county (Radon411 reads a share from 30 tests up). Wayne County beside the counties around it is how this page reads it.
What these figures count
Only 9 tests were reported to CDC for Wayne County over 2022, 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: 2022. Measured data period: 2005 to 2022 (every CDC figure on file).
Wayne County, Compared
Wayne County radon figures, compared
Calculated by Radon411CDC's largest figure for Wayne County rests on 26 tests over the 2008 to 2017 laboratory totals, 2 of them at or above 4 pCi/L, so each test moves its share by 3.8 points and no rank or comparison is drawn from it. Results reached as high as 7.6 pCi/L, with a middle value of 1.7 pCi/L.
Of the counties bordering it, 5 have a figure over the 2008 to 2017 laboratory totals: Perry County reported the largest share at or above 4 pCi/L, 32.5%, and Hardin County the smallest, 7.9%, with Lauderdale County, AL at 27.2%, Lawrence County at 21.3% and Lewis County at 16.1% between. Farther out, Giles County (43 miles away) at 40.7%, Hickman County (43 miles away) at 35.0% and McNairy County (44 miles away) at 8.5% 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 Wayne County in Zone 1, the map's highest label: a predicted county average above 4 pCi/L. USGS geology rates 77% of the county's land high radon potential.

The ground under Wayne County
PredictedMost of the ground under Wayne County is one class on USGS's geologic map: 76.7% of its land is high radon potential, with 23.3% low. The map puts 75.9% of Wayne County in the area it calls Cherty Highland and 23.3% in Tombigbee Hills, with one smaller area beside them. USGS gives the first a radon index of 12, in the high band (12 to 17), and the second 8, in the low band (5 to 8).
| Area | The rock, in USGS's words | Potential | Radon index | Share of land |
|---|---|---|---|---|
| Cherty Highland | Cherty dolostone. | High | 12 | 75.9% |
| Tombigbee Hills | Clay, sand, sandstone, chalk, chalky marl, quartzose, chert gravels, and quartz sand. | Low | 8 | 23.3% |
| Interior Low Plateaus | Mississippian carbonate rocks and shales. | High | 12 | 0.8% |
