Radon tests reported for Randolph County, 2008 to 2017, laboratory
CDC holds 15 reported tests for Randolph County over the 2008 to 2017 laboratory totals, with a median of 3.7 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 15 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 Radon411CDC's largest figure for Randolph County rests on 15 tests over the 2008 to 2017 laboratory totals, 6 of them at or above 4 pCi/L, so each test moves its share by 6.7 points and no rank or comparison is drawn from it. Results reached as high as 16.6 pCi/L, with a middle value of 3.7 pCi/L.
Of the counties bordering it, 4 have a figure over the 2008 to 2017 laboratory totals: Carroll County, GA reported the largest share at or above 4 pCi/L, 40.5%, and Clay County the smallest, 17.9%, with Troup County, GA at 33.9% and Cleburne County at 18.8% between. Farther out, Calhoun County (39 miles away) at 18.9%, Talladega County (41 miles away) at 18.5% and Lee County (48 miles away) at 12.3% 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 Randolph County in Zone 2, its middle label: a predicted county average between 2 and 4 pCi/L. USGS geology rates 70% of the county's land moderate radon potential.
Pooled shares: Radon411's sum of CDC's county counts for one period.
Randolph County, Geology
The ground under Randolph County
PredictedUSGS's geologic map splits Randolph County: 69.6% of its land is moderate radon potential and 13.8% high and 16.6% low. The map puts 69.2% of Randolph County in the area it calls Northern Piedmont and 16.6% in Inner Piedmont, with one smaller area beside them. USGS gives the first a radon index of 9, in the moderate band (9 to 11), and the second 7, in the low band (5 to 8).
| Area | The rock, in USGS's words | Potential | Radon index | Share of land |
|---|---|---|---|---|
| Northern Piedmont | Graphitic schists, phyllites, and felsic gneiss. | Moderate | 9 | 69.2% |
| Inner Piedmont | Amphibolite, ultramafic rocks, gneiss, schist, minor granite. | Low | 7 | 16.6% |
| Northern Piedmont | Schist, metagraywake, phyllite, quartz diorite gneiss, amphibolite gneiss, quartz monzonite. | High | 12 | 13.8% |
