In this paper a new kind of process of ranking x-ray transmission information in the range 20 - 150 keV is described. This ranking method can be applied to other energy ranges and to other particles. Based on a classical statistical method, Principal Component Analysis, it can be applied to continuous transmission measurement as multi- energy method. In this case, the effective Z sensitivity is in the neighboring of 0.001, i.e. 5 times better than the classical dual-energy method. A x-ray imaging application: the explosive device detection systems of Heimann systems is described using both multi-energy model and this ranking process. It provides good quality radiographic images and accurate chemical identification. The entire methodology described in the article is covered by three international patents.
