Assignee: KOREA ATOMIC ENERGY RESEARCH INSTITUTE
Field: Measurement (Instruments)
Classification: CPC G | IPC G

Claim 0:
1. A security screening device, comprising:
a radiation generator configured to produce an X-ray and neutron radiation and irradiate the X-ray and the neutron radiation toward an inspection object;
an inspection object transfer unit configured to change a position of the inspection object;
a radiation detector configured to detect an X-ray and neutron radiation passed through the inspection object; and
at least two gamma ray detectors that are installed adjacent to the inspection object and are configured to detect a gamma signal generated from the inspection object;
wherein the radiation detector obtains image information of the inspection object using radiation information detected from the X-ray and the neutron radiation passed through the inspection object, and
wherein a controller, configured to control the radiation detector and the radiation detector, analyzes the detected gamma signal to analyze the inspection object, and identifies a location of a hazardous material contained in the inspection object from the image information,
wherein the at least two gamma ray detectors are located parallel to each other and are located along an entirety of each side of the inspection object transfer unit respectively.
