EPA Zone 3: lower predicted potential

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

Measured: tests reported to CDC

Radon tests reported for Tallapoosa County, 2008 to 2017, laboratory

CDC holds 16 reported tests for Tallapoosa County over the 2008 to 2017 laboratory totals, with a median of 0.9 pCi/L: too few to describe a county (Radon411 reads a share from 30 tests up). Tallapoosa County beside the counties around it is how this page reads it.

What these figures count

Only 16 tests were reported to CDC for Tallapoosa 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).

Tallapoosa County, Compared

Tallapoosa County radon figures, compared

Calculated by Radon411

CDC's largest figure for Tallapoosa County rests on 20 tests over the 2005 to 2014 laboratory totals, 4 of them at or above 4 pCi/L, so each test moves its share by 5.0 points and no rank or comparison is drawn from it. Results reached as high as 11.7 pCi/L, with a middle value of 1.7 pCi/L.

Of the counties bordering it, 3 have a figure over the 2008 to 2017 laboratory totals: Elmore County reported the largest share at or above 4 pCi/L, 22.2%, and Lee County the smallest, 12.3%, with Clay County at 17.9% between. Farther out, Talladega County (42 miles away) at 18.5%, Montgomery County (50 miles away) at 9.7% and Autauga County (54 miles away) at 17.1% have figures too. Pooled across 65 Alabama counties, 21.9% of reported tests reached that level; across every county in the country with a figure, 35.7%.

Statewide for the same period, Colbert County reported the highest share (36.2%) and Baldwin County the lowest (0.0%). EPA's 1993 map puts Tallapoosa County in Zone 3, its lowest label: a predicted county average under 2 pCi/L. USGS geology rates 57% of the county's land low radon potential.

Tallapoosa County, Geology

The ground under Tallapoosa County

Predicted

USGS's geologic map splits Tallapoosa County: 57.3% of its land is low radon potential and 42.7% moderate. The map puts 57.3% of Tallapoosa County in the area it calls Inner Piedmont and 39.4% in Northern Piedmont, with one smaller area beside them. USGS gives the first a radon index of 7, in the low band (5 to 8), and the second 9, in the moderate band (9 to 11).
