Title: Map shows average "equivalent uranium" concentrations
Description: This U.S. 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. The map was derived from aerial monitoring conducted by the U.S. Geological Survey in the 1970's National Uranium Resource Evaluation program.
