In this work different weight percent of copper and zinc powders of 20 ìm particlesize were blended carefully with grease , and the final weight of samples are 2 g . Thesamples were placed in containers were made from tephlon of 2.5 cm as a diameter . Thebottom window of container was fitted with 6 ìm mylar film . The samples weresubjected to X- ray fluorescence to measure the Cu Ká and Zn Ká lines intensities .Sensitivity (m) and Lower Limit Detection (LLD) were calculated and plotted againstthe weight fraction for all samples .
