GAMMAN is a toolbox that allows for the efficient automated analysis of large series of gamma spectra, obtained during geophysical surveys. The software contains an implementation of the full spectrum analysis (FSA) method developed by Medusa Radiometrics BV in collaboration with the Centre for Advanced Radiation Technologies (KVI-CART) of the University of Groningen (NL). FSA comprises the mathematically most efficient method to derive nuclide concentrations from gamma ray spectra. The method uses virtually all spectral data present in a gamma spectrum to derive nuclide concentrations.

Check out the chapters in this documentation space for the Gamman manual, How-To's, Q&A etcetera. The Gamman documentation can be browsed by using the docs tree on the left of this page. Part can be accessed directly by pressing teh F1 key in the Gamman application.
