EPA Zone 3: lower predicted potential

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

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

CDC holds 6 reported tests for Randolph County over the 2008 to 2017 laboratory totals, with a median of 1.6 pCi/L: too few to describe a county (Radon411 reads a share from 30 tests up). Randolph County beside the counties around it is how this page reads it.

What these figures count

Only 6 tests were reported to CDC for Randolph 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).

Randolph County, Compared

Randolph County radon figures, compared

Calculated by Radon411

CDC's largest figure for Randolph County rests on 6 tests over the 2008 to 2017 laboratory totals, 1 of them at or above 4 pCi/L, so each test moves its share by 16.7 points and no rank or comparison is drawn from it. Results reached as high as 5.8 pCi/L, with a middle value of 1.6 pCi/L.

The nearest counties with a figure are Dougherty County (35 miles away) at 0.0%, Muscogee County (52 miles away) at 2.1% and Harris County (68 miles away) at 10.9%. 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 Randolph 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.

Testing a home in Randolph County

No CDC figure names Randolph County; the nearest county with one, Dougherty County (35 miles away), reported 0.0% 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 Randolph County.
