INTERACTION OF KEV PHOTONS WITH MATTER AND NEW APPLICATIONS

The fundamental interactions of keV photons with matter, i.e. photoelectric effect and coherent and incoherent scattering are treated from a non-traditional point of view. Section 1 is designed to lay a foundation of the basic science. Section 2 deals with non-imaging analytical techniques that have been developed over the past 20 or so years. These techniques include energy-dispersive X-ray fluorescence, Compton profile measurements, and general scattering techniques. In section 3, imaging techniques are described. These imaging techniques utilize the details of section 1, and some expand on techniques described in section 2. This section finishes with discussions of "traditional" computerized tomography (CT) techniques followed by newer developments such as differential tomography, Compton tomography, coherent scatter tomography, and fluorescent X-ray tomography.
