Claim 18:
19. A system for enhanced security threat detection, the system comprising:
means for irradiating a target during an irradiation period with source x-rays from a stationary x-ray source having an end-point energy of at least 88 keV;
means for enabling motion of the target with respect to the stationary x-ray source during the irradiation period;
means for detecting resulting x-rays received from the target resulting from the irradiating during the irradiation period;
means for generating an image of an interior of the target based on the detected, resulting x-rays;
means for performing analysis of the image for an indication of a weapon;
means for producing signals representing an energy spectrum of the resulting x-rays;
means for analyzing the signals for characteristic x-ray fluorescence that can be emitted from lead potentially present in the target;
means for providing an indication, based on the signals, of a probability of lead ammunition being present in the target; and
means for outputting an indication of likelihood of a security threat in the target based on the analysis of the imaged for the indication of a weapon and on the probability of lead ammunition being present.
