Neutron gamma integrated detection system

The invention discloses a neutron gamma integrated detection system. The neutron gamma integrated detection system at least comprises a detection module, a control module, a display module and a transmission module, an unmanned aerial vehicle detection device at least comprises an unmanned aerial vehicle detection device body, an undercarriage is arranged below the unmanned aerial vehicle detection device body, and supporting legs are fixed to the two sides of the undercarriage; and a detection box is arranged between the two supporting legs, a lifting block is arranged in the detection box, and a plurality of probes are fixed to the lifting block. The unmanned aerial vehicle detection device carries the probes to detect a target site, so that potential safety hazards are reduced, the detection efficiency is improved, and meanwhile, under the action of the lifting block, the probes are located in the detection box when not used, so that the probability that the probes are damaged whennot used is reduced, the
