Abstract: An inspection system, including: at least one ray source (100) rotatable between at least two scanning positions around a rotation axis, and a rotation angle of at least one ray source between two adjacent scanning positions is greater than an angle of adjacent target spots of each ray source (100) relative to the rotation axis; a detector assembly (200), and a conveying device (300) configured to carry an object to be inspected. At least one ray source (100) and the detector assembly (200) are movable in a traveling direction relative to the conveying device (300), so that the object (10) to be inspected may enter an inspection region (30). When at least one ray source (100) is located at one of scanning positions, at least one ray source (100) and the detector assembly (200) move in the traveling direction relative to the conveying device (300) and at least one ray source (100) emits X-rays; after at least one ray source (100) and the detector assembly (200) move a predetermined distance in the traveling direction relative to the conveying device (300), at least one ray source (100) rotates around the rotation axis to another of scanning positions.

Abstract: Provided are a method for detecting an explosive, including: receiving a detection signal to generate a detection spectrum, wherein the detection spectrum is a spectrum of a gamma ray generated by a reaction between an object to be detected and neutrons; deducting a detection background in the detection spectrum to obtain a first processing spectrum; deducting a characteristic peak at a nickel peak position in the first processing spectrum to obtain a second processing spectrum; and determining whether the explosive is contained in the object to be detected, based on the second processing spectrum. A device for detecting an explosive and a computer readable storage medium are further provided.
