Book excerpt: A rapid x-ray fluorescence (XRF) method for the quantitative analysis of uranium in ore and process samples is demonstrated. The method requires no uranium ore standards and provides a relative precision of +-2.5 percent. Particle-size and self-absorption effects are evaluated along with current methods of excitation and detection for M, L, and K series uranium x-rays. Sensitivities and detection limits are comparable using either energy dispersive or wavelength dispersive analysis of uranium L x-rays, and wavelength dispersive analysis of uranium M x-rays for both thick and thin samples. The XRF methods are more sensitive than the analysis of uranium by 252Cf neutron-induced .gamma.-ray analysis or by direct photon analysis of uranium daughters.

This book was released on 2015 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: Uranium ore can be easily detected due to various gamma-ray energies emitted from uranium daughters particularly from 238U daughters such as 214Bi, 214Pb and 226Ra. After uranium is extracted from uranium ore, only low energy gamma-rays emitted from 235U may be detected if the detector is placed in close contact to the specimen. In this research, identification and characterization of uranium bearing materials is experimentally investigated using direct measurement of gamma-rays from 235U in combination with the x-ray fluorescence (XRF) technique. Measurement of gamma-rays can be conducted by using high purity germanium (HPGe) detector or cadmium telluride (CdTe) detector while a 57Co radioisotope-excited XRF spectrometer using CdTe detector is used for elemental analysis. The proposed technique was tested with various uranium bearing specimens containing natural, depleted and enriched uranium in both metallic and powder forms. The results indicated that combination of the two techniques can be used to identify and to characterize suspicious nuclear materials not only uranium bearing materials but also Plutonium (Pu) and Thorium (Th).

Available in PDF, EPUB and Kindle. Book excerpt: X-ray fluorescence (XRF) techniques were applied extensively to impurity analysis in bulk materials, including minerals. The variant on this method, which is to use radioisotope sources to provide the incident photon flux, is much less well developed. This study determined whether the use of 133Ba showed promise for Au. A simple X-ray fluorescence system allowing for flexibility in source-sample-detector geometry was constructed and a spectrometer was adopted which is relatively transparent to high energy photons. Reference powdered ore samples containing known amounts of gold were used and a detection limit was extracted.
