Multichannel processing for airborne gamma-ray spectrometry
The conventional approach to the processing of airborne gamma-ray spectrometric data is to first sum the observed spectra over three relatively broad energy windows. These three window count rates are then processed to obtain estimates of the potassium (K), uranium (U), and thorium (Th) elemental abundances. However, multichannel spectra contain additional information on the concentrations of K...
متن کاملThe 3D inversion of airborne gamma-ray spectrometric data
Gamma radiation measurements are made at airborne survey heights and, through suitable processing, are converted to estimates of the count rates due to the radioelements (K, U and Th) at each observation point along the flight lines. The conventional processing of these data would include a correction for deviations in the aircraft height from the nominal survey height. The elemental count rate...
متن کاملMonte Carlo Simulation for Airborne Gamma Ray Spectrometry
The aerial measuring terrestrial gamma radiation from airborne platforms is a useful method for characterizing the radiation levels over large areas. Because of the advantage of Monte Carlo method, it is very suitable for simulation of gamma ray transport and interaction with media (soil, air, aircraft and detector), which offer alternative means of estimating detector response and calibration ...
متن کاملUseful surrogates of soil texture for plant ecologists from airborne gamma‐ray detection
Plant ecologists require spatial information on functional soil properties but are often faced with soil classifications that are not directly interpretable or useful for statistical models. Sand and clay content are important soil properties because they indicate soil water-holding capacity and nutrient content, yet these data are not available for much of the landscape. Remotely sensed soil r...
متن کاملAirborne Gamma-Ray Spectrometry in 2017: solid ground for new development
Decades of development and operational usage have brought airborne gamma-ray spectrometry (AGRS) to maturity. This has been recognized by the publication in the 1990s of standard guidelines that have been accepted by industry and governments and that are in worldwide use today. Over the last decade, while still based on the same proven system configuration favoring high volume detector arrays, ...
