Abstract
The present invention relates a security screening device, comprising: a radiation generator for respectively generating X-rays and neutron beams and irradiating same toward an inspection object; an inspection object transfer unit for changing the position of the inspection object; a radiation detector configured to respectively detect X-rays and neutron beams transmitted through the inspection object; and a gamma ray detector installed adjacent to the inspection object and configured to detect a gamma signal generated from the inspection object, wherein the radiation detector acquires image information of the inspection object by using radiation information detected from the X-rays and neutron beams that have passed through the inspection object, and the gamma ray detector analyzes the detected gamma ray to detect the location of the inspection object from the analysis of the inspection object and the image information.
