Radioactivity

Release of subatomic particles from earth materials. Generally the energy of these particles is used to determine the chemical elements present.
This category is also used for gamma ray emission.

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.

Info
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.

Info
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.

Info
Radiometric Survey in Western Afghanistan: A Website for Distribution of Data

Radiometric (uranium, thorium, potassium content and gamma-ray intensity) and related data were digitized from radiometric and survey route location maps of western Afghanistan previously published by others in 1976.

Info
Radon in soils of parts of Cameron, Hidalgo, and Willacy Counties, Texas

Analysis of soil samples in the Texas borderland area

Info
Solid-phase data from cores at the proposed Dewey Burdock uranium in-situ recovery mine, near Edgemont, South Dakota

Geochemical and mineralogical analysis of uranium-bearing sandstone in order to help understand mineral deposits of this type.

Info
Surface mineral maps of Afghanistan derived from HyMap imaging spectrometer data, version 2

The report presents new maps from data collected in 2007 and the processing steps applied to that data. The maps are being used for natural resource development and to prioritize study areas of mineral distribution to assist with economic revitalization.
