Locations and reports
EPA puts Page County in Zone 1, its highest radon zone, and 38.3% of its 141 reported radon tests (2008 to 2017, laboratory totals) were at or above 4 pCi/L. Homes with elevated levels occur in all three zones, so only a test measures yours.

Page County, Compared
In Page County, about 4 in 10 reported tests over the 2008 to 2017 laboratory totals (54 of 141) were at or above EPA's action level. Against the national pool of 35.7%, the gap is 2.6 points higher. Across 131 Virginia counties pooled together, 30.4% of tests reached that level, so Page County runs 7.9 points above its state.
Of 6 neighbours with a figure, 3 reported a larger share at or above 4 pCi/L and 3 a smaller one; the spread is 34.6% (Greene County) to 44.0% (Madison County). By share, Page County is 33rd of 84 Virginia counties with 30 or more tests for the same period.
Half the tests came in under 3.3 pCi/L and half over it; the single highest reached 26.9 pCi/L. Below the action level, 44 tests (31.2%) came in under 2 pCi/L, against 44.7% statewide, and 43 tests (30.5%) fell between 2 and 4, against 24.9% statewide.
Zone 1 on EPA's map (predicted average above 4 pCi/L) and a 38.3% share point the same way here. USGS geology rates 69% of the county's land high radon potential. CDC also counts 17 tests taken after mitigation in Page County for the same period: tests in homes where a fix was already in.
CDC's ten-year totals for Page County went from 91 tests (2005 to 2014) to 141 (2008 to 2017), the share going from 37.4% to 38.3%.

Page County, Geology
USGS's geologic map splits Page County: 68.8% of its land is high radon potential and 31.2% moderate. The map puts 68.8% of Page County in the area it calls Valley and Ridge and 31.2% in Blue Ridge. USGS gives the first a radon index of 15, in the high band (12 to 17), and the second 10, in the moderate band (9 to 11).
| Area | The rock, in USGS's words | Potential | Radon index | Share of land |
|---|---|---|---|---|
| Valley and Ridge | Cambrian dolomite, limestone, shale, and sandstone, Silurian-Ordovician limestone, dolomite, shale, and sandstone, Mississippian-Devonian sandstone, shale, limestone, gypsum, and coal. | High | 15 | 68.8% |
| Blue Ridge | Granite, pegmatite, monazite, schist, and gneiss. | Moderate | 10 | 31.2% |
