The EPA classifies Blair County as Zone 1 because the predicted average indoor radon screening level exceeds 4 pCi/L. This is primarily due to the geological composition of the area — certain rock types (granite, shale, phosphate) naturally contain higher concentrations of uranium, which decays into radon gas.

In Zone 1 counties like Blair County, a significant percentage of homes test above the EPA's 4.0 pCi/L action level. While every home is different, the probability is substantially higher than the national average. Testing is essential before making any purchase decision.
