8. β1 fluorescence at 17,220 eV was monitored continuously with a 13-element Ge detector. X-ray absorption data were analyzed with the EXAFSPAK code
9. 2 grid spacing was used to approximately match the U fluorescence sampling depth, with 30 s of data acquisition per pixel. The U concentration reference was National Institute of Standards and Technology standard reference material 612 (37 ppm of U in a glass matrix).
