The performances of two variants of XRF elemental analysis, i.e. the Energy Dispersive XRF (EDXRF) developed by the Radioactive Waste Management Department Laboratory (DMDR-Lab) at the National Institute for Physics and Nuclear Engineering and the Wavelength Dispersive XRF (WDXRD) developed by the Spectroscopy Laboratory (LS) in the ArcelorMittal Company, Galati were compared by analysing the content of major, rock forming elements of 10 samples of loess and paleosol collected from the Costinesti (South-Eastern Dobrogea) loess deposit.
The results concerning the content of Na, Mg, Al, Si, K, Ca, Ti and Fe as determined by both methods were coincident within the experimental uncertainties as the t-test confirmed. Accordingly, the t parameter varied between -0.0139 and -0.0447 at p between 0.9649 and 0.9862 respectively.
