Abstract


The Present study is a conntinuation of the program of measuring natural radioactivity in different environmental media in Qena, Red sea and Aswan, Upper Egypt. Gamma­ ray spectrometry in radiation physics laboratory at Qena have been applied to estimate radioactivities and hence the concentrations of uranium-238, thorium-232 and potassium-40 in young and old granite samples collected from Aswan areas (Gebel Ibrahim pacha, El-shellal, El-sheikh harun and Sehyel island) and Wadi allaqi (180Km southeastren Aswan, upper Egypt).



Uranium-238 and Thorium-232 activities were determined vt•a the•tr gamma emt•ttm• g daughters (2'4Pb, 214B1• , £or uram.um and 212Pb, 228Ac and 208Tl for Thorium) under the assumption of radioactive equilibrium, while potassium-40 is a direct
gamma ray emitter.
