摘要： There is presented a screening system and a corresponding method for screening an item. The screening system includes a detection apparatus (100), a rotatable platform (310) to receive the item, and a mechanical arrangement (320, 330). The detection apparatus has an emitter portion to generate a primary beam of ionising radiation and a detector portion to detect an absorption signal and at least one of a diffraction signal and a scattering signal. The mechanical arrangement is adapted to translate the detection apparatus along a translation axis to scan the item with the primary beam. The screening system may be used for identifying restricted or illicit substances that may be present in some luggage or in mail.
