摘要：

Uranium ores from various locations in Canada were analyzed by X-ray spectroscopy. A 10 mCi 57Co point source was employed and mounted on a one dimensional goniometer. This instrument was designed with adjustable scatter angle, primary and secondary collimation settings. The optimum geometrical conditions for analysis of uranium using partially thick powdered ore samples were found. Assumptions can be drawn for innate geological specimens which lead to the direct calculation of the matrix and thickness factors. This is accomplished by simultaneously and experimentally measuring the Compton scattering and transmitted peak intensities. These factors are then used to modify the U Kαi peak intensity so that no comparative standards are required to maintain accuracy. As such, the technique is a prime candidate for application to on-stream industrial analysis. © 1979.
