The HIGH-RADON PROJECT:
NURE: County Uranium Concentrations Data File
A data file containing county-average surficial uranium concentrations for the
United States is available here. These data were developed by averaging the uranium
data in each county from the database of Duval et al. ("Equivalent uranium map of
conterminous United States," U.S. Geological Survey Open-File Report 89-478, 1989, 12 pages),
which was based on the data from the National Uranium Resource Evaluation program, conducted
by the U.S. Department of Energy in the 1970s. The uranium concentrations serve as an
indicator of surficial radium concentrations, and hence of radon generated in the soil.
This file is available here, and the full set of U.S. data is available from the USGS..
