EPA Zone 3: lower predicted potential

is EPA's lowest class, and its forecast for Tipton County as a whole is an average indoor of less than 2 pCi/L (less than 75 Bq/m³). A low zone clears no address in it: homes above EPA's turn up in all three zones.

What these figures count

Only 1 test was reported to CDC for Tipton County over 2023, 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: 2023. Measured data period: 2005 to 2023 (every CDC figure on file).

Tipton County, Compared

Tipton County radon figures, compared

Calculated by Radon411

Only 4 of 89 radon tests reported for Tipton County over the 2007 to 2016 laboratory totals reached 4 pCi/L (4.5%). The median result, 1.0 pCi/L, sits below 2, well under EPA's 4 pCi/L action level, and the top reported result was 5.1 pCi/L.

The newest figure, in 2023, counts only 1 test (0.0% at or above 4 pCi/L), too few to compare, so this reading uses the 89-test figure.

Across 95 Tennessee counties pooled together, 33.4% of tests reached that level, so Tipton County runs 28.9 points below its state. Against the national pool of 35.8%, the gap is 31.3 points lower. Its place in the state: 75th of 77 Tennessee counties with 30 or more tests for the same period.

Zone 3 on EPA's map (predicted average under 2 pCi/L) and a 4.5% share point the same way here. Of 2 neighbours with a figure, all 2 reported a larger share at or above 4 pCi/L; the spread is 7.0% (Shelby County) to 11.2% (Fayette County).

Below the action level, 74 tests (83.1%) came in under 2 pCi/L, against 42.3% statewide, and 11 tests (12.4%) fell between 2 and 4, against 24.3% statewide. USGS geology rates 100% of the county's land low radon potential.

The busiest year on file was 2022, with 6 tests reported; the quietest, 2023, had 1.

Tipton County, Geology

The ground under Tipton County

Predicted

USGS's geologic map puts all of Tipton County's mapped land in one class: low radon potential. The map puts 81.6% of Tipton County in the area it calls Loess-Covered Coastal Plain and 17.9% in Mississippi Alluvial Plain. USGS gives the first a radon index of 8 and the second 7, both in the low band (5 to 8).
