Radon tests reported for Canadian County, 2008 to 2017, laboratory
CDC holds 21 reported tests for Canadian County over the 2008 to 2017 laboratory totals, with a median of 0.6 pCi/L: too few to describe a county (Radon411 reads a share from 30 tests up). Canadian County beside the counties around it is how this page reads it.
What these figures count
Only 21 tests were reported to CDC for Canadian 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).
Canadian County, Compared
Canadian County radon figures, compared
Calculated by Radon411CDC's largest figure for Canadian County rests on 21 tests over the 2008 to 2017 laboratory totals, 4 of them at or above 4 pCi/L, so each test moves its share by 4.8 points and no rank or comparison is drawn from it. Results reached as high as 199.4 pCi/L, with a middle value of 0.6 pCi/L.
Oklahoma County, the one bordering county with a figure over the 2006 to 2015 laboratory totals, reported 8.9% of its tests at or above 4 pCi/L. Farther out, Tulsa County (121 miles away) at 6.0%, Washington County (142 miles away) at 11.3% and Cherokee County (170 miles away) at 32.0% have figures too. Pooled across 53 Oklahoma counties, 12.6% of reported tests reached that level; across every county in the country with a figure, 36.3%.
Statewide for the same period, Delaware County reported the highest share (44.7%) and Tulsa County the lowest (6.0%). EPA's 1993 map puts Canadian 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.
Canadian County, Geology
The ground under Canadian County
PredictedUSGS's geologic map puts all of Canadian County's mapped land in one class: low radon potential. All of it lies in the area the map calls Central Oklahoma Plains and Hills, to which USGS gives a radon index of 7, in the low band (5 to 8).
| Area | The rock, in USGS's words | Potential | Radon index | Share of land |
|---|---|---|---|---|
| Central Oklahoma Plains and Hills | Nonmarine Permian and Tertiary rocks, including shale, sandstone, and conglomerate in the western part, and Mississippian and Pennsylvanian rocks in the eastern part. | Low | 7 | 100% |

Canadian County beside the ground around it
Across Oklahoma 0.6% of the land is rated high; none of Canadian County's is. None of the 8 counties that border it has any moderate-potential ground either.

Testing a home in Canadian County
No CDC figure names Canadian County; the nearest county with one, Oklahoma County (32 miles away), reported 8.9% of its tests at or above 4 pCi/L over the 2006 to 2015 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 Canadian County.

Canadian County, Cities and towns
Cities and towns in Canadian County
Canadian County is growing: the Census Bureau puts it at 187,189 residents on July 1, 2025, up 20.4% from 155,435 in 2020. That works out to 209 people per square mile of land. Oklahoma City, the largest place on its list (719,849 residents in all), extends beyond Canadian County, so no share of the total is worked out for it. Reported testing is thin here: 21 tests over 2008 to 2017, or 0.1 for every 1,000 residents (2025 estimate), where Oklahoma as a whole comes to 0.2.
From Oklahoma City to Calumet, CDC publishes no figure by town: each reads Canadian County's.
