This paper describes a rapid method for the determination of uranium dioxide in stainless steel by direct X-ray fluorescent analysis after chemical solution of the sample in perchloric acid. Strontium is used as an internal standard. X-ray fluorescence methods of analysis have many advantages over the commonly used chemical methods such as the colorimetric, gravimetric and volumetric, because elements which ordinarily interfere need not be separated before analysis. Statistically, eleven independent solutions were counted and nine sets of results were obtained on each one. Standard deviations are shown.
