title: Gamma spectrum unfolding for a NaI monitor of radioactivity in aquatic systems.
abstract: Spectrum unfolding is a powerful method that can enhance the readability of experimental energy spectra obtained by detectors of poor resolution. It is applied to the NaI-based monitor. The UMG 3.3 package is used for unfolding the experimental spectra with the response matrix obtained by MCNP4c2. The main parameter influencing the quality of the results is the chi(2). The goal of this study is to optimize the choice of this factor. The statistical accuracy of the technique is evaluated.
