4. CONCLUSION 
The present work revealed the presence of several new radioactive 
sites in the Central part of the Eastern Desert. These occurrences 
are located along N-S and NNE-SSW trending fault zones, within 
the granitic rocks and contrary to those recorded by Ramadan et 
al., (1999) which occur along NW-SE trending fault zones, within 
the Miocene clastic-carbonate sediments. The radioactive 
anomalies are associated with the alkali granites, pegmatitic and 
manganese veins, trachytic dykes at Gabal Hamrat Ghanam, 
Gabal El Delihmi, Gabal Nusla and Gabal Abu El Tiyur 
respectively 
Detailed chemical and mineralogical studies for these 
ureniferous sites are recommended. The results of the present 
study demonstrate the accuracy of airborne radiometric data as 
well as the suitability of the remote sensing technique for 
exploration for radioactive material.
