EPA Zone 3: lower predicted potential

is EPA's lowest class, and its forecast for Bledsoe 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 Bledsoe 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).

How to read these figures

Bledsoe County, Compared

Bledsoe County radon figures, compared

Calculated by Radon411

Bledsoe County's 37 reported tests over the 2008 to 2017 laboratory totals had a middle value of 2.1 pCi/L and a maximum of 21.1 pCi/L, and 24.3% reached 4 pCi/L. Tennessee as a whole (95 Tennessee counties, pooled) comes to 33.3%: 9.0 points higher than here.

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 37-test figure.

Among its state's counties it ranks 51st of 80 Tennessee counties with 30 or more tests for the same period. Statewide for the same period, Jefferson County reported the highest share (56.8%) and Chester County the lowest (0.0%).

Below the action level, 17 tests (45.9%) came in under 2 pCi/L, against 42.4% statewide, and 11 tests (29.7%) fell between 2 and 4, against 24.3% statewide. The busiest year on file was 2022, with 3 tests reported; the quietest, 2023, had 1.

EPA's 1993 zone map puts Bledsoe County in Zone 3, a predicted county average under 2 pCi/L. USGS geology rates 100% of the county's land low radon potential.

Next door, the shares run from 8.7% in Cumberland County to 26.7% in Rhea County, with Sequatchie County, Hamilton County and Cumberland County below Bledsoe County.
