Abstract: There is provided a portable cadmium zinc telluride image identification system that uses an X-ray source with a novel sensing mitt that can be worn or held by the user. The sensing mitt is connected to a display that may be a stand-alone display, worn as glasses or otherwise integrated into the sensing mitt. The sensing mitt contains a detector array such as, but not limited to, a cadmium zinc telluride crystal or a plurality of crystals in a matrix. A collimator is placed in front of the sensing surface of the cadmium zinc telluride crystal and a processor is used to convert a representation of the electrical signals received from the cadmium zinc telluride crystal or similar detector array into display signals that are used by the display to provide an image of the subject of interest.

Abstract: There is provided a System and Method For Determining The Radiological Composition of Material Layers Within a Conduit. The system and method disclosed is equally applicable to pipes, vessels, and conduits as well as medical applications such as determining vessel thickness, occlusion, scarring, or the like in humans and animals. A phantom setup is disclosed that has a phantom containing a test standard such as a reactor water test standard, removable plates, a collimator and probe with a spectrometer display. The phantom setup provides a baseline data set that can be used in conjunction with field measurements to determine the composition of materials within the conduit, such as corrosion or the like. The baseline data set may be semi-logarithmic and contains spectrometer readings of various plate thicknesses or quantities of plates.

Abstract: An improved system for detection and analysis of microscopic flaws in objects such as high-speed turbine blades collimates the gamma radiation emanating from flaws in an object treated with a radioactive gas, preferably xenon-133, to form a gamma-photon virtual image of a surface of the object showing flaws therein. A scintillation plate transforms the gamma-photon virtual image into a photoelectron virtual image. A chevron microchannel plate pair (MCP) multiplies the number of electrons comprising the photoelectron virtual image by a factor of at least 10.sup.5. The multiplied photoelectron virtual image can be converted to visible output information relatable to the flaws in the object by directing it onto a phosphor-coated plate. The scintillator, microchannel plate multiplier, and phosphor plate are contained in a housing shielded with lead to screen out signal noise from cosmic radiation. The housing is subjected to a pressure of about 10.sup.-7 Torr.
