The four sites represent breccia pipe uranium deposits in the Grand Canyon Region in various lifecycle stages of mining: EZ2 complex (exploration), Arizona 1 mine (standby), Pinenut mine (closed, pre-reclamation), and Kanab North Mine (reclaimed). The data were collected to assess the potential of fallout radionuclides (Cs-137 and unsupported Pb-210) to help understand the distribution of subsurface contaminants related to mining activity. Gamma spectroscopy determinations were performed on archive samples from November 2018 that were collected during a previous investigation, which is cited below. The Pb-210, Pb-214, and Bi-214 data can be used to calculate Ra-226 and excess (unsupported) Pb-210.
