Method: Alpha track
In home: 90 days to 12 months
Locations and reports
EPA puts Lincoln County in Zone 1, its highest radon zone, and only 12 radon tests from it are on file with CDC (2008 to 2017, laboratory totals). Homes with elevated levels occur in all three zones, so only a test measures yours.

Measured: tests reported to CDC
CDC holds 12 reported tests for Lincoln County over the 2008 to 2017 laboratory totals, with a median of 2.1 pCi/L: too few to describe a county (Radon411 reads a share from 30 tests up). Lincoln County beside the counties around it is how this page reads it.
Only 12 tests were reported to CDC for Lincoln 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).
Lincoln County, Compared
CDC's largest figure for Lincoln County rests on 14 tests over the 2007 to 2016 laboratory totals, 3 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 11.7 pCi/L, with a middle value of 1.1 pCi/L.
Of the counties bordering it, 6 have a figure over the 2008 to 2017 laboratory totals: White Pine County reported the largest share at or above 4 pCi/L, 39.1%, and Mohave County, AZ the smallest, 4.1%, with Iron County, UT at 22.4%, Washington County, UT at 14.8% and Nye County at 11.1% between. Farther out, Churchill County (230 miles away) at 12.4%, Elko County (243 miles away) at 40.3% and Lyon County (253 miles away) at 30.4% have figures too. Pooled across 16 Nevada counties, 22.8% of reported tests reached that level; across every county in the country with a figure, 35.7%.
Statewide for the same period, Carson City reported the highest share (40.6%) and Clark County the lowest (8.1%). EPA's 1993 map puts Lincoln County in Zone 1, the map's highest label: a predicted county average above 4 pCi/L. USGS geology rates 64% of the county's land moderate radon potential.

Lincoln County, Geology
USGS's geologic map splits Lincoln County: 63.7% of its land is moderate radon potential and 27.1% high and 9.2% low. The map puts 63.6% of Lincoln County in the area it calls Great Basin and 27.1% in Great Basin, with one smaller area beside them. USGS gives the first a radon index of 11, in the moderate band (9 to 11), and the second 12, in the high band (12 to 17).
| Area | The rock, in USGS's words | Potential | Radon index | Share of land |
|---|---|---|---|---|
| Great Basin | Sandstone, shale, limestone, mafic volcanic rocks. | Moderate | 11 | 63.6% |
| Great Basin | Tertiary volcanic rocks composed of silicic ash-flow tuffs, rhyolitic flows, shallow intrusive rocks, andeside, and some tuffaceous sedimentary rocks. | High | 12 | 27.1% |
| Great Basin | Sandstone, shale, limestone, mafic volcanic rocks. | Low | 8 | 9.2% |
