Data processing in Airborne Gamma-Ray Spectrometry (AGRS) is a system of procedures for solving a geophysical inverse problem, i.e., estimating the distribution of radioactive isotopes in the ground by measuring gamma radiation in air. In these problems, some simplifications and approximations common in geophysics are natural and by: 2. Airborne gamma-ray data is collected by either helicopter or aeroplane, typically between 60 to metres flying height above the surface. Sodium-iodide scintillation crystals on the aircraft measure gamma-rays emanating from the surface. Photomultiplier tubes attached to the scintillation crystals AIRBORNE GAMMA-RAY SPECTROMETRY.
In the last few years, the use of gamma-ray spectrometry for geological mapping and mineral exploration has shown considerable growth. With this growth, there has developed an increasing need to standardize the airborne measurements so that they will be independent of survey parameters. This will allow data. Environmental monitoring and in situ gamma spectrometry An important aspect of airborne spectrometry data interpretation is variations of real experimental conditions in comparison with approximated parameters used for the model response calculation. Airborne Gamma Ray Spectrometry—Methods, Data Processing and Applications, 21st Cited by: airborne gamma-ray spectrometer data has stimulated a new interest in the use of these data for regional geological mapping. The application demands sensitive detection equipment and sophisticated data processing procedures. This report, after describing the basic principles involved, reviews recent advancesFile Size: 8MB.

Airborne / Mobile Gamma-Ray Spectrometry. Pico provides spectrometer systems that can be installed on Helicopter or fixed-wing platform. Depending on the survey requirements and/or budget, the spectrometers can be used as a stand-alone unit or it can be combined with Data Acquisition system and other ancillaries to make it a complete survey. The airborne gamma-ray spectrometry (AGRS) data in the GDR were acquired by a series of more than surveys over 30 years, from about to , using a variety of aircraft and instrument packages. The aircraft flew along a pattern of parallel flight lines typically at m terrain clearance (height above the ground). comprehensive report on radioelement mapping using gamma ray spectrometry. The authors of this publication are known and recognized specialists from four countries involved in mapping and data treatment using spectrometry. They all have extensive experience in the application and use of gamma ray spectrometry for radioelement Size: 2MB. Airborne gamma-ray spectrometry has been used for many years for effective mapping of Potassium (K), Uranium (U) and Thorium (Th) over large areas, for direct detection of ore bodies and in support of lithological mapping. In AGRS, the object of data acquisition is to obtain a gamma-ray spectrum covering the.
