Radon tests reported for Talbot County, 2008 to 2017, laboratory
CDC holds 26 reported tests for Talbot County over the 2008 to 2017 laboratory totals, with a median of 1.1 pCi/L: too few to describe a county (Radon411 reads a share from 30 tests up). Talbot County beside the counties around it is how this page reads it.
What these figures count
Only 26 tests were reported to CDC for Talbot 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).
Talbot County, Compared
Talbot County radon figures, compared
Calculated by Radon411CDC's largest figure for Talbot County rests on 26 tests over the 2008 to 2017 laboratory totals, 2 of them at or above 4 pCi/L, so each test moves its share by 3.8 points and no rank or comparison is drawn from it. Results reached as high as 33.7 pCi/L, with a middle value of 1.1 pCi/L.
Queen Anne's County, the one bordering county with a figure over the 2008 to 2017 laboratory totals, reported 16.9% of its tests at or above 4 pCi/L. Farther out, Calvert County (30 miles away) at 30.2%, Anne Arundel County (32 miles away) at 17.4% and Kent County (33 miles away) at 52.6% have figures too. Pooled across 24 Maryland counties, 23.9% of reported tests reached that level; across every county in the country with a figure, 35.7%.
Statewide for the same period, Washington County reported the highest share (56.0%) and Wicomico County the lowest (0.0%). EPA's 1993 map puts Talbot County in Zone 3, its lowest label: a predicted county average under 2 pCi/L. USGS geology rates 81% of the county's land low radon potential.

The ground under Talbot County
PredictedUSGS's geologic map puts all of Talbot County's mapped land in one class: low radon potential. 81.4% of it lies in the area the map calls Eastern Shore, to which USGS gives a radon index of 7, in the low band (5 to 8).
