1. A system for detecting and identifying at least one predetermined foreign element in a substance, the system comprising:
a measurement device comprising: a radiation source assembly comprising at least one source of X-ray radiation or Gamma-ray radiation, each source of the at least one source being configured to generate X-ray radiation or Gamma-ray radiation having predetermined properties and a predetermined solid angle of radiation emission to excite a portion of the substance located in a region within the predetermined solid angle of radiation emission to cause an X-ray response of the portion of the substance; a radiation detection assembly comprising at least one detector having a solid angle of radiation detection overlapping with the predetermined solid angle of radiation emission, each detector of the at least one detector being configured and operable to detect an X-ray radiation propagating within a solid angle of radiation detection and generate measured data indicative of the X-ray response of the portion of the substance, including a relative displacement between the substance and at least one of the radiation source assembly and the radiation detection assembly along a movement path; the measurement device being configured and operable such that the measured data is indicative of a time variation of the X-ray response of the portion of the substance;
a flow line arrangement comprising a translation assembly configured and operable for translating at least one of the radiation source assembly and the radiation detection assembly with respect to the movement path; and
a control unit configured and operable for a data communication with the radiation detection assembly to receive and analyze the measured data, the control unit comprising a signal processor configured and operable to identify in the measured data a pattern of a signal variation over time indicative of a location of at least one foreign element carrying an X-ray responsive marker in the substance.
