Abstract	Contaminated soils present a major global health problem especially in urban areas with dense population. The common contaminants of soil are heavy metals. For risk – assessment studies and follow-up remediation projects is necessary to perform numerous analyses to determine the concentration of metal contaminants. To minimize the need for laboratory analysis of soil samples, the XRF – technology can be used for screening the metal contamination in soil, with significant advantages. This method provided significant accuracy and well documented to support field decision making with reduced overall costs. The new generation of portable XRF instruments is equipped with miniatures X-ray tubes in order to reduce the regulatory demands encountered with radioactive isotopes. The goal of this experiment was to complete the data obtained in the preliminary tests, by observing the influence of soil particle size and the metal concentration in soil upon the XRF results. The XRF results are presented comparatively with laboratory analysis data. From these results is evident that the soil particle size have no important influence upon the XRF data, an important factor appears to be the metal concentration in soil.
