The analysis of leiomyomata uteri and uterus using energy-dispersive X-ray fluorescence spectrometry.

The X-ray fluorescence method was used to determine concentrations of the elements present in leiomyomata uteri and uterus. The physical basis of the analytical method used, experimental set-up, procedure of sample preparation, and the results are presented. The equipment used for this study was a Si(Li) detector, a multichannel analyzer, and 55Fe and 241Am radioisotope sources. The energy-dispersive X-ray fluorescence technique has been successfully used for the determination of elements present in leiomyomata uteri and uterus.
