The paper presents the scientific tasks, description, and comparison of various gamma and neutron spectrometers that can be installed on board a medium-class lunar rover with a mass up to 100 kg. As a specific example, we consider the scientific equipment proposed for the future Russian mission Luna-Grunt, the main purpose of which is the delivery of lunar polar regolith samples to the Earth. Presumably, the payload of this mission allows for inclusion of a small lunar rover with a mass between 30 and 100 kg. For this reason, the paper considers options for a gamma and neutron spectrometer that would allow finding the optimal ratio between scientific requirements and resources available on board such a lunar rover.
