Mineral Resources On-Line Spatial Data
Mapping of gamma radiation from the earth's surface with airborne scintillation meters or gamma-ray spectrometers.
Aerial gamma-ray survey for parts of Cameron, Hidalgo, and Willacy Counties, Texas The USGS had an aerial survey flown over parts of Cameron, Hidalgo, and Willacy Counties in Texas. The aerial survey included measurements of the earth's magnetic field and of the radioactivity of the surface rocks and soils.
Aerial gamma-ray surveys in Alaska Measurements indicating abundance of radioactive elements in near-surface rocks. Grids and flight-line data from surveys flown 1976-1980.
Aerial gamma-ray, Landsat TM, and digital elevation data, Big Bend area, Texas This report presents the results of analyses and interpretation of aerial gamma-ray, Landsat TM, geologic, and digital elevation data of the Big Bend area in Texas.
Aerial magnetic, electromagnetic, and gamma-ray survey, Berrien county, Michigan Maps, grids, and flight-line databases of a detailed aerial survey and maps and grids of satellite data
Aeromagnetic and aeroradiometric data for the conterminous United States and Alaska from the National Uranium Resource Evaluation (NURE) program of the U.S. Department of Energy Aeroradiometric and aeromagnetic flight-line data from surveys flown at 400 feet with line spacing from 3 to 6 miles from 1974 through 1981.
Gamma-ray, magnetic, and topographic data for parts of the Colorado Front Range Five geospatial grids from the NURE surveys, showing potassium, uranium, and thorium concentration, residual magnetic field, and digital elevation.
Merged aeroradiometric data for Alaska Gridded data from aeroradiometric surveys of Alaska.
National geophysical data grids; gamma-ray, gravity, magnetic, and topographic data for the conterminous United States Gridded geophysical data in a variety of formats.
Terrestrial radioactivity and gamma-ray exposure in the United States and Canada Flight-line databases and derived grids from aeroradiometric surveys across the US carried out during the 1970s
Terrestrial radioactivity and gamma-ray exposure in the United States and Canada Data generated by aerial sensing of radiation emanating from the earth's surface provides general estimates of the geographic distribution of Uranium, Thorium, and Potassium in surficial and bedrock units. Covers the conterminous United States, southeaste
