Abstract
Last decades showed a high demand for the radioactive raw materials, largely uranium, for the manufa turing of the nee ssary fuel 1’01’ the cperati Il of nuclea reactor ,especially those used for the production of electrical energy. Consequently, tile explorariou activities of the Nuclear Materials Authority (NMA) of Egypt coudu ted comprehensive exploration pmgmms to search for uranium miueralizations in Egypt. The e programs led 10 the dig every of radioa rive anomalies and uranium mineralization ill he uortheru, central and southern Ea tern De eli of Egypt b id ,illai At the astern D e11. 1110 t of the di covered uranium occurrence are spatially and genetically . related to the younger granites, TIle most prounsuig uranium occurrences are Gebal (G.) attar, G. El Mis -ikal. ,EI Erediya and . Um AnI. Since thaI rime tJIC granitoid roc’ especially the young r granite , became more attractive to ’MA due 10 their as ociatiou with anomalous cone ntration of radioactive elements,
