Um Taghir area located along the shear zone of the Qena-Safaga road, mostly it represents one of the most important occurrences of radioactive elements in the Central Eastern Desert of Egypt. The current study aims to calculate the content of the radioactive elements of the investigated granitic rocks by radiative methods for the geochemical parameters. Major oxides such as SiO 2 , Al 2 O 3 , Fe 2 O 3 , CaO, MgO, TiO 2 , P 2 O 5 , Na 2 O and K 2 O in addition to trace and rare earth elements (Cr, Ni, Cu, Zn, Zr, Rb, Y, Ba, Pb, Sr, Ga, V, Nb, As and Co) are measured by (X-ray fluorescence (XRF) and Inductively Coupled Plasma-Mass Spectrometry (ICP-MS). The average activity (range) of  238 U series,  232 Th series and  40 K were 15.7 (8.7–25.7), 13.2 (4.7–11.7) and 703.8 (195.1–1371.8) Bq/kg, respectively. The average concentrations values of  226 Ra,  232 Th are lower than those of the world’s average and the average activities in Egyptian soil. While in the case of potassium ( 40 K), we find that the radioactive content is greater than the world’s average, and also the radioactive average of the Egyptian soil. The scope of estimated exercises generally contrasted as their quality in rocks tests relies upon their physical, synthetic and geo-concoction properties and the appropriate condition.
