Radon tests reported for Nome Census Area, 2022
| Year | Share of reported tests at or above 4 pCi/L |
|---|---|
| 2020 | 0.0% |
| 2022 | 0.0% |
2022: 0.0%. Across these years the share ran from 0.0% to 0.0%. Each column counts radon tests reported to CDC that year, not homes.
What these figures count
Only 2 tests were reported to CDC for Nome Census Area over 2022, and tests are often run on homes being sold or already suspected of a problem: so few describe neither the borough or census area nor this house.
Measured: CDC tracking data. Figure above: 2022. Measured data period: 2020 to 2022 (every CDC figure on file).
Nome Census Area, Compared
Nome Census Area radon figures, compared
Calculated by Radon411CDC's largest figure for Nome Census Area rests on 2 tests in 2022, 0 of them at or above 4 pCi/L, so each test moves its share by 50.0 points and no rank or comparison is drawn from it. Results reached as high as 1.6 pCi/L, with a middle value of 0.9 pCi/L.
The nearest counties with a figure are Matanuska-Susitna Borough (479 miles away) at 14.3%, Fairbanks North Star Borough (513 miles away) at 19.4% and Anchorage Municipality (535 miles away) at 3.1%.

The ground under Nome Census Area
PredictedUSGS's geologic map puts all of Nome Census Area's mapped land in one class: moderate radon potential. 96.8% of it lies in the area the map calls Central Alaska, to which USGS gives a radon index of 11, in the moderate band (9 to 11).
| Area | The rock, in USGS's words | Potential | Radon index | Share of land |
|---|---|---|---|---|
| Central Alaska | Uraniferous granites, felsic intrusives; clastic and carbonate sedimentary rocks; metamorphic, and volcanic rocks. | Moderate | 11 | 96.8% |
