COLEGRAM is a freely available spectrometry software dedicated to the study of ionizing radiation spectra. It can handle alpha, beta, gamma and X-ray spectra, proposing twenty-eight specific peak shapes in order to fit complex spectra using the non-linear least-squares fitting method. Different optimization cost functions can be used to perform the mathematical adjustment, which is guided by a user-friendly interface. COLEGRAM is also able to perform batch processing on a large number of spectra copying fitted peak information, based on a predefined model. General characteristics of the code and typical application examples are given to illustrate its potential.
