Claim 19:
20. An x-ray scanning system comprising:
an x-ray source configured to irradiate a target with source x-rays having an end-point energy of at least 88 keV during an irradiation period;
a set of energy-resolving detectors configured to detect resulting x-rays received from the target resulting from the irradiation during the irradiation period and to produce energy spectrum signals representative of an energy spectrum of the resulting x-rays;
a set of imaging detectors configured to detect x-rays selected from the group consisting of resulting x-rays that are scattered from the target during the irradiation period, resulting x-rays that are transmitted through the target during the irradiation period, and combinations thereof;
the set of imaging detectors further configured to output imaging signals representative of an x-ray image of an interior of the target;
an image generator configured to generate an image an x-ray image of the interior of the target based on the imaging signals; and
an analyzer configured to analyze the signals for characteristic x-ray fluorescence (XRF) that can be emitted from lead potentially present in the target and to provide an indication, based on the signals, of a probability of lead ammunition being present in the target,
the analyzer further configured to use the probability and the x-ray image to determine a likelihood of a security threat in the target.
