摘要： A device (1) for detecting neutrons and gamma rays comprises at least one detector (2) and an acquisition and data-analysis system (3), connected to the detector (2); the detector (2) comprises an active part (7) that is formed by a plurality of: scintillator layers (8), made of a scintillator material, in particular a plastic scintillator; and absorber layers (9), containing at least one neutron-absorbing material, in particular cadmium or gadolinium; the acquisition and data- analysis system (3) is configured so as to: analyse the signals coming from the detector (2) and calculate the total energy released within the detector (2) following upon an interaction with gamma rays or neutrons; and discriminate between gamma rays and neutrons impinging upon the detector (2) according to whether the energy detected is higher or lower than a pre-set threshold.
