SPECTRALLY SHAPED X-RAY INSPECTION SYSTEM

摘要

A system and methods for non-invasive x-ray inspection of an enclosure in such a manner as to reduce the ambient radiation dose to below a specified level. A beam spectrally filtered to emphasize a high-energy component of penetrating radiation is interleaved, temporally, with a beam dominated by a low-energy component. Thus both lightly loaded and heavily loaded cargo may be inspected while limiting the ambient scattered radiation.
