Radon tests reported for Bladen County, 2021
| Year | Share of reported tests at or above 4 pCi/L |
|---|---|
| 2014 | 0.0% |

What these figures count
Only 4 tests were reported to CDC for Bladen County over 2021, 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: 2021. Measured data period: 2005 to 2021 (every CDC figure on file).
Bladen County, Compared
Bladen County radon figures, compared
Calculated by Radon411CDC's largest figure for Bladen County rests on 14 tests over the 2008 to 2017 laboratory totals, 0 of them at or above 4 pCi/L, so each test moves its share by 7.1 points and no rank or comparison is drawn from it. Results reached as high as 1.9 pCi/L, with a middle value of 0.1 pCi/L.
Of the counties bordering it, 3 have a figure over the 2008 to 2017 laboratory totals: Robeson County reported the largest share at or above 4 pCi/L, 3.8%, and Columbus County the smallest, 0.0%, with Cumberland County at 1.9% between. Farther out, Brunswick County (42 miles away) at 0.0%, New Hanover County (47 miles away) at 3.4% and Scotland County (54 miles away) at 3.2% have figures too. Pooled across 99 North Carolina counties, 22.6% of reported tests reached that level; across every county in the country with a figure, 35.7%.
Statewide for the same period, Transylvania County reported the highest share (47.8%) and Nash County the lowest (0.0%). EPA's 1993 map puts Bladen 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.
Pooled shares: Radon411's sum of CDC's county counts for one period.
Bladen County, Geology
The ground under Bladen County
PredictedUSGS's geologic map puts all of Bladen County's mapped land in one class: low radon potential. All of it lies in the area the map calls Inner Coastal Plain, to which USGS gives a radon index of 8, in the low band (5 to 8).
| Area | The rock, in USGS's words | Potential | Radon index | Share of land |
|---|---|---|---|---|
| Inner Coastal Plain | Fossiliferous clay and sand, shelly sand, sandy marl, and limestone. | Low | 8 | 100% |

Bladen County beside the ground around it
Across North Carolina 1.3% of the land is rated high; none of Bladen County's is. None of the 5 counties that border it has any moderate-potential ground either.
