<p>This study investigates the principle and capabilities of Dual Energy X-Ray Radiography/Tomography when applied on nuclear and related materials. The dual-energy X-ray technique is a significant improvement to X-ray imaging systems and gives additional information on the composition of the object being imaged. Within this technique, two radiographs are obtained at two distinct X-ray energies and are combined (divided, subtracted) to give detailed information about the material features with improvement of the image contrast. X-rays for this research, will be generated with a new 225 kV microfocus X-ray system to be commissioned by June 2011 at the Nuclear Energy Cooperation of South Africa (Necsa). This system will be able to generate different peak energy X-rays at different anode target materials at very small focal spot sizes in order to obtain high-resolution images. Different X-ray filters will be utilized to shape the energy of the X-ray beam for high energy X-rays to interact with the material. This presentation focuses on the principles of X-ray generation with different anode materials and the utilization thereof in radiographs and tomograms.
