Extract

In a previous publication, we compared measurements of the x-ray microfluorescence of calcium and iron from homogeneous spherical glass particles with the results of Monte Carlo simulation. That work was performed to verify a Monte Carlo model developed for the characterization of particle size effects using a polished flat sample of the same composition as a reference standard. The present work extends our comparison to synthetic glass particles containing elements of higher atomic number. We also modified our Monte Carlo model to include simulation of x-ray fluorescence from elements in irregular shaped synthetic particles. In addition, the Compton scattering from spherical and irregular shaped particles was simulated using Monte Carlo and compared with experimental measurements.
