The results of neutron-activation measurements performed using the model of planetary soil and detectors based on high-purity germanium (HPGe) and cerium bromide (CeBr3) are reported. Gamma lines lying in the energy range from 200 keV to 8 MeV are used as indicators to compare these two types of detectors in experiments with the model irradiated by 14-MeV neutrons from a pulse neutron generator. The results will aid the design of scientific instruments for the active neutron and gamma spectroscopy of planet surfaces in future Russian and international lander missions (Luna-Glob, Luna-Resurs, and ExoMars-2020).
