Gamma Gen - a Computer Code for Gamma-ray Spectra Generation

''GammaGen'' is a Windows software, developed at The Nuclear Research Center Negev (NRCN) to generate synthetic gamma ray spectra obtained with a Nal(TI) scintillation detector and a solid state Ge detector. The information on a chosen radio-nuclide is generated according to its activity, its photo peak energy and yield (taken from a data library). The detector efficiency and resolution, and peak to Compton dependence are used to generate a pulse height spectrum for a specific detector. The spectra can be displayed in several modes: as energy lines of the photo peaks, as Gaussian of each photo peak, or as sum of all Gaussians. The Compton continuum can be included as well. The spectra mixture for different nuclides can be produced for visual analysis. All spectra can be exported to formats required by commercial spectra analyzing programs. There are several purposes for developing of the program: - to generate synthetic spectra for predicting the detectors response in case of a nuclear reactor accident. - to check operational limits and performances of commercial spectrum unfolding programs. - to develop a training tool for spectrometry laboratory workers
