Lebanon County, Compared
Lebanon County radon figures, compared
Calculated by Radon411More than half: 54.2% of the 1,102 radon tests reported to CDC for Lebanon County in 2020 read at least 4 pCi/L. That places it 2nd of 63 Pennsylvania counties with 30 or more tests for the same period. That is 23.9 points above the 30.3% pooled from 67 Pennsylvania counties.
The median result, 4.8 pCi/L, sits above EPA's 4 pCi/L action level, and the top reported result was 1145.0 pCi/L. The rest split 33.9% under 2 pCi/L and 11.9% from 2 to 4 (Pennsylvania: 44.3% and 25.4%). Zone 1 on EPA's map (predicted average above 4 pCi/L) and a 54.2% share point the same way here.
No bordering county with a figure for the same period reported a higher share; the closest is Schuylkill County at 53.5%, the lowest Dauphin County at 36.9%. Statewide for the same period, Perry County reported the highest share (57.7%) and Philadelphia County the lowest (10.6%).
The busiest year on file was 2015, with 2,261 tests reported; the quietest, 2014, had 908.
Over 7 years of annual figures the share fell 2.7 points, from 56.9% in 2014 to 54.2% in 2020; its peak was 56.9% in 2014. Nationally, every county with a figure for the same period pools to 25.5%; Lebanon County sits 28.7 points above it.

Lebanon County, Geology
The ground under Lebanon County
PredictedUSGS's geologic map puts all of Lebanon County's mapped land in one class: high radon potential. The map puts 68.5% of Lebanon County in the area it calls Great Valley Section and 16.7% in Newark Basin, with 2 smaller areas beside them. USGS gives the first a radon index of 15 and the second 12, both in the high band (12 to 17).
| Area | The rock, in USGS's words | Potential | Radon index | Share of land |
|---|---|---|---|---|
| Great Valley Section | Sandstone, shale and siltstone. | High | 15 | 68.5% |
| Newark Basin | Gray shale and fluvial sandstone. | High | 12 | 16.7% |
| Appalachian Mountain Section | Paleozoic sandstone, shale, and limestone. | High | 12 | 13.9% |
| New England Province/Reading Prong | Granitic gneiss. | High | 15 | 1.0% |
