X-ray chemical monitoring of uranium oxide

Scientists at Los Alamos National Laboratory have recently reported the X-ray analysis of uranium oxideα-U₃O₈ samples under controlled temperatures and humidities. They found that the combined use of powder X-ray diffraction and U L-III EXAFS can help in identifying temporal changes of uranium oxide stored for a number of years. For more information, see the paper, "Oxidation and Hydration of U₃O₈ Materials Following Controlled Exposure to Temperature and Humidity", A. L. Tamasi et al., Anal. Chem. 87, 4210 (2015).
