“…This visual inspection is followed by the Energy Dispersive X-Ray Fluorescence (EDXRF) as rapid and cheap. The EDXRF spectrometry [1] , [2] , [3] is a non-destructive nuclear method used to characterize samples in the view of their elemental composition. EDXRF spectrometry is applicable for production quality control, ecological environment monitoring, geological surveying (including the applications of µ-EDXRF), food safety, and heritage analysis, among others [4 , 5] .…”

“…The preparation method for Energy Dispersive X-Ray Fluorescence spectrometry was described by Guembou et al. [1] , [2] , [3] and many other authors [7 , 8] . Prepared samples are disposed on the plate for spectrometer analysis (or on the rack depending on the type of spectrometer used) and fixed in the spectrometer chamber as depicted in Fig.…”

This Study presents a method to recover and label unknown samples in a nuclear laboratory using Energy Dispersive X-Ray Fluorescence (EDXRF) spectrometry based on spectra differentiation and analysis. This method was found to be a new powerful tool that can be used in different laboratories where a certain number of samples cannot be identified because they have never been identified, their labeling and identification cannot be assessed because of degradation, and/or any other causes. The method was found to be simple, timely appropriate, not expensive, and powerful in identifying and recover the information needed for a sample. The EDXRF spectrometry method for recovering unknown samples in laboratories was based on the following three main points: EDXRF method allows the elemental characterization of any sample without clear identification in a laboratory; The displaying of several samples’ spectra on the same graph allows direct comparison and identification when the sample's data overlap one of the stored data; and The identification of the unknown sample based on the EDXRF results: The faster method being the overlapping comparison while the elemental characterization-based identification needs high skilled expertise in X-ray fluorescence analysis.
