Radon Levels in Pike County, Alabama

EPA Zone 3: lower predicted potential

is EPA's lowest class, and its forecast for Pike 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 Pike County, 2008 to 2017, laboratory

CDC holds 9 reported tests for Pike County over the 2008 to 2017 laboratory totals, with a median of 1.7 pCi/L: too few to describe a county (Radon411 reads a share from 30 tests up). Pike County beside the counties around it is how this page reads it.

What these figures count

Only 9 tests were reported to CDC for Pike 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).

Pike County, Compared

Pike County radon figures, compared

Calculated by Radon411

CDC's largest figure for Pike County rests on 14 tests over the 2006 to 2015 laboratory totals, 4 of them at or above 4 pCi/L, so each test moves its share by 7.1 points and no rank or comparison is drawn from it. Results reached as high as 7.1 pCi/L, with a middle value of 1.3 pCi/L.

Montgomery County, the one bordering county with a figure over the 2008 to 2017 laboratory totals, reported 9.7% of its tests at or above 4 pCi/L. Farther out, Elmore County (56 miles away) at 22.2%, Lee County (65 miles away) at 12.3% and Autauga County (65 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 Pike County in Zone 3, its lowest label: a predicted county average under 2 pCi/L. USGS geology rates 54% of the county's land low radon potential.

Pike County, Geology

The ground under Pike County

Predicted

USGS's geologic map splits Pike County: 53.7% of its land is low radon potential and 46.3% moderate. The map puts 53.7% of Pike County in the area it calls Coastal Plain and 46.3% in Inner Coastal Plain. USGS gives the first a radon index of 7, in the low band (5 to 8), and the second 10, in the moderate band (9 to 11).

From Troy to Banks, CDC publishes no figure by town: each reads Pike County's.
