Radon Levels in Lincoln County, Nebraska

EPA puts Lincoln County in Zone 3, its lowest radon zone, and most reported tests there come back low, though 12.2% of 271 (2023) reached 4 pCi/L. Homes with elevated levels occur in all three zones, so only a test measures yours.

Calculated by Radon411

Lincoln County reports fewer high tests than Nebraska overall. 12.2% of its 271 tests in 2023 were at or above 4 pCi/L. That is 26.0 points below the 38.2% pooled from 86 Nebraska counties.

Ordered from highest share down, it comes 32nd of 33 Nebraska counties with 30 or more tests for the same period. Nationally, every county with a figure for the same period pools to 33.4%; Lincoln County sits 21.2 points below it.

Dawson County, the one bordering county with a figure for the same period, reported 18.6%. Zone 3 on EPA's map (predicted average under 2 pCi/L) and a 12.2% share point the same way here.

Half the tests came in under 2.1 pCi/L and half over it; the single highest reached 14.5 pCi/L. The rest split 41.3% under 2 pCi/L and 46.5% from 2 to 4 (Nebraska: 39.2% and 22.6%). Year by year, 2014 opened at 27.3% and 2023 closed at 12.2% (down 15.1 points), with 2015 the high at 27.6%.

The busiest year on file was 2016, with 1,104 tests reported; the quietest, 2022, had 183.

The ground under Lincoln County

Predicted

USGS's geologic map splits Lincoln County: 62.2% of its land is low radon potential and 25.2% high and 12.6% moderate. The map puts 62.2% of Lincoln County in the area it calls Sand Hills and 25.2% in Loess over K-T, with 2 smaller areas beside them. USGS gives the first a radon index of 8, in the low band (5 to 8), and the second 13, in the high band (12 to 17).
