1. A device for simultaneous detection, identification, quantification and location of a gamma radiation source and a neutron source, the device comprising:
a mechanical collimator for neutrons that is transparent to gamma radiation, intended for being positioned in front of the gamma radiation source and neutron source, wherein the mechanical collimator is of a type selected from a pin-hole, slit, parallel hole, converging, diverging, multiple pin-hole and coded mask type mechanical collimator,
a detection module, comprising:
a first detector with neutron detection and/or gamma-neutron discrimination capability, coupled to the mechanical collimator,
one or more gamma radiation detectors, positioned after the first detector, on a face opposite the mechanical collimator,
wherein the first detector and the one or more gamma radiation detectors form a Compton camera;
a processing and acquisition module, associated with the first detector and with the gamma radiation detectors, and configured to select time-coincident events between detectors and to apply a Compton imaging technique.
