Predicted: EPA radon zone

EPA Zone 2: moderate predicted potential

Cherokee County is a county: EPA's forecast for it as a whole is an average indoor of 2 to 4 pCi/L (75 to 150 Bq/m³). It describes no single address, and homes above EPA's are found in every zone, this one included.

Cherokee County, Compared

Cherokee County radon figures, compared

Calculated by Radon411

Cherokee County's 1,154 reported tests over the 2008 to 2017 laboratory totals had a middle value of 2.0 pCi/L and a maximum of 35.7 pCi/L, and 17.6% reached 4 pCi/L. Georgia as a whole (129 Georgia counties, pooled) comes to 24.8%: 7.2 points higher than here.

Among its state's counties it ranks 45th of 57 Georgia counties with 30 or more tests for the same period. Statewide for the same period, Barrow County reported the highest share (48.3%) and Richmond County the lowest (0.0%).

Below the action level, 555 tests (48.1%) came in under 2 pCi/L, against 44.0% statewide, and 396 tests (34.3%) fell between 2 and 4, against 31.2% statewide. CDC's ten-year totals for Cherokee County went from 748 tests (2005 to 2014) to 1,154 (2008 to 2017), the share going from 16.4% to 17.6%.

EPA's 1993 zone map puts Cherokee County in Zone 2, a predicted county average between 2 and 4 pCi/L. USGS geology rates 100% of the county's land moderate radon potential.

Next door, the shares run from 13.0% in Forsyth County to 37.6% in Pickens County, with Cobb County and Forsyth County below Cherokee County.

CDC also counts 72 tests taken after mitigation in Cherokee County for the same period: tests in homes where a fix was already in.

Cherokee County, Geology

The ground under Cherokee County

Predicted

USGS's geologic map puts all of Cherokee County's mapped land in one class: moderate radon potential. The map puts 59.9% of Cherokee County in the area it calls Georgiabama Thrust Stack (North) and 40.1% in Georgiabama Thrust Stack (South). USGS gives both a radon index of 9, in the moderate band (9 to 11).
