GAMMAN is a toolbox that allows for the efficient automated analysis of large series of gamma-ray spectra, obtained during geophysical surveys.
The software contains an implementation of the full spectrum analysis (FSA) method developed by Medusa Explorations BV in collaboration with the Center for Advanced Radiation Technology of the University of Groningen (Netherlands).
FSA comprises the mathematically most efficient method to derive nuclide concentrations from gamma-ray spectra. The method utilizes virtually all spectral data present in a gamma-ray spectrum to derive nuclide concentrations.
Handle large datasets conveniently
GAMMAN provides a convenient interface to handle large datasets. It provides different data views (spectral as well as column based views) and methods for selecting and filtering parts of the data. In GAMMAN, each data record consists of a gamma-ray spectrum, and additional information (for instance a GPS position of the measurement, a depth value in case of a borehole measurement, environmental information like elevation or air pressure etc).
Several tools are provided to manipulate these data, create selections, and delete parts of the data. Also, file import filters are provided to allow for parsing gamma-ray data from several suppliers of gamma-ray sensors.
