Radon Levels in Crisp County, Georgia

EPA puts Crisp County in Zone 3, its lowest radon zone, and only 1 radon test from it is on file with CDC (2008 to 2017, laboratory totals). Homes with elevated levels occur in all three zones, so only a test measures yours.

EPA Zone 3: lower predicted potential

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

CDC holds 1 reported test for Crisp County over the 2008 to 2017 laboratory totals, a result of 0.1 pCi/L: too few to describe a county (Radon411 reads a share from 30 tests up). Crisp County beside the counties around it is how this page reads it.

What these figures count

Only 1 test was reported to CDC for Crisp 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).

Crisp County, Compared

Crisp County radon figures, compared

Calculated by Radon411

CDC's largest figure for Crisp County rests on 2 tests over the 2007 to 2016 laboratory totals, 1 of them at or above 4 pCi/L, so each test moves its share by 50.0 points and no rank or comparison is drawn from it. Results reached as high as 8.4 pCi/L, with a middle value of 4.3 pCi/L.

The nearest counties with a figure are Houston County (37 miles away) at 8.2%, Dougherty County (38 miles away) at 0.0% and Bibb County (61 miles away) at 0.0%. Pooled across 137 Georgia counties, 23.9% of reported tests reached that level; across every county in the country with a figure, 35.8%.

Statewide for the same period, Barrow County reported the highest share (51.0%) and Dougherty County the lowest (0.0%). EPA's 1993 map puts Crisp County in Zone 3, its lowest label: a predicted county average under 2 pCi/L. USGS geology rates 100% of the county's land low radon potential.

Crisp County, Geology

The ground under Crisp County

Predicted

USGS's geologic map puts all of Crisp County's mapped land in one class: low radon potential. All of it lies in the area the map calls Coastal Plain, to which USGS gives a radon index of 8, in the low band (5 to 8).

Testing a home in Crisp County

No CDC figure names Crisp County; the nearest county with one, Houston County (37 miles away), reported 8.2% of its tests at or above 4 pCi/L over the 2007 to 2016 laboratory totals, the only reading nearby until a test of this home. Zone 3 is the lowest label, yet homes at or above 4 pCi/L occur in every zone: a short-term kit (2 to 90 days) is the quick first check in Crisp County.
