Title: Map shows average "equivalent uranium" concentrations
Description: This Minnesota County map shows average "equivalent uranium" concentrations in parts per million, which are proportional to the radium concentrations in the soil. LBL researchers have found that these concentrations correlate closely with indoor radon concentrations. This map was derived from aerial monitoring conducted by the U.S. Geological Survey in the 1970s for the National Uranium Resource Evaluation program.
