GammaSpec
A complete solution for the calibration of airborne gamma-ray spectrometers and the processing of airborne radiometric data
GammaSpec is a Windows program for the processing of 256-channel airborne and portable gamma-ray spectrometric data. It provides all the tools required for the calibration and processing of such data. The airborne tools operate off either Intrepid or Geosoft databases, and come with a complete set of demonstration datasets for processing and calibration.
