A gamma spectrometer based on LaBr3(Ce) crystal has been developed. The spectrometer uses a compact data acquisition system including a multi-channel analyzer and corresponding electronics components. The response function of the detector has been simulated using Monte Carlo Code (MCNPX 2.7E). It has been also tested, at the University of Ontario Institute of Technology radiation facilities, using a series of gamma radiation sources. The simulated data has been compared with experiments and a good agreement has been achieved. This paper presents the parameters of the developed spectrometer and the results of its testing along with a comparison with NaI(TI) crystal.
