This manual was prepared as an aid to those interested in the interpretation and application of high-sensitivity aerial gamma-rayspectrometer data in uranium exploration. Particular emphasis is on the first 10 radiometric surveys performed under the National Uranium Resource Evaluation (NURE) program. The primary purpose of aerial gamma-rayspectrometer surveys in the NURE program is to map regional distributions of near-surface natural radioelements, i.e., the uranium and thorium decay series, and potassium-40. These data along with an understanding of the geochemical behavior of the pertinent isotopes under a variety of conditions allow uranium-enriched areas of the earth's crust (uraniferous provinces) to be identified as part of the regional appraisal phase of prospecting. Uranium ore deposits tend to occur more frequently in these generally enriched regions than elsewhere, and, consequently, uraniferous provinces constitute preferred territory for follow-up exploration methods such as detailed aerial or surface radiometric prospecting, geological studies, etc., to define potential prospects. These in turn may be investigated by still more detailed surface geological studies perhaps supplemented by radon or uranium geochemical surveys and exploration drilling and logging. This manual outlines the fundamentals of uranium geology and geochemistry along with interpretive approaches which may be used to identify statistically and geochemically significant uranium anomalies and uraniferous provinces. Follow-up prospecting methods are summarized along with guides to recent literature. Specific suggestions are made as to interpretive approaches and applicable follow-up prospecting procedures tailored to fit the data characteristics and general environment of each of the first 10 NURE aerial gamma-rayspectrometer surveys performed by Geodata International, Inc. and Texas Instruments Incorporated

 This manual of arms was prepared as an aid to those interested in the rendition and lotion of high - sensitivity aerial da gamma - rayspectrometer data in uranium exploration. Particular stress is on the inaugural 10 radiometric surveys performed under the National Uranium Resource Evaluation (NURE) program. The primary purpose of aeriform gamma - rayspectrometer surveys in the NURE program is to map regional distribution of near - surface lifelike radioelements, i.e., the uranium and thorium decay series, and potassium-40. These datum along with an understanding of the geochemical behavior of the pertinent isotopes under a variety of conditions permit uranium - enriched areas of the earth's crust (uraniferous provinces) to be identified as share of the regional appraisal phase of prospect. Uranium ore deposits tend to occur more frequently in these generally enriched regions than elsewhere, and, consequently, uraniferous provinces constitute preferred district for keep up - up exploration methods such as detailed aeriform or open radiometric prospect, geological studies, etc. , to define likely prospects. These in bend may be investigated by still more detailed open geological studies perhaps supplemented by radon or uranium geochemical surveys and exploration drilling and logging.
