Evaluation of Radon Occurrence in Groundwater from 16 Geologic Units in Pennsylvania, 19862015, with Application to Potential Radon Exposure from Groundwater and Indoor Air (PaRadonGW)

Results from 1,041 groundwater samples (U.S. Geological Survey, 2016) collected during 1986‒2015 from 16 geologic units in Pennsylvania, associated with 25 or more groundwater samples with concentrations of radon-222, were evaluated to create this dataset in an effort to identify variations in radon-222 activities or concentrations and to classify potential radon-222 exposure from groundwater and
