    Abstract :

    In this paper, the measurement of specific activity concentrations in eleven commercial granite samples from different countries (China, Brazil, Iran, Syria , Turkey , Spain , Italia ,Egypt , Lebanon , India, and Jordan) were carried out using (HPGe) detector. The results of measurements have shown that the average values specific activity concentrations for 238U, 232Th and 40K which were equal to (22.944±2.71 Bq/kg), (23.195±2.77 Bq/kg) and (169.956±37.18 Bq/kg) , respectively., which were less than the corresponding recommended global values reported by (UNSCEAR , 2000) publication. The radiation hazard indices [Raeq ,DƔ , (AED) in ,(AED) out , Iɣ , Iα, Hin and Hex] were also studied. The obtained results were also found to be less than the allowed limits given by (UNSCEAR , 2000) and (RPA, 2000). Thus all results obtained in the present work have shown no significant radiological hazard when the studied granites is used, for example, for construction of buildings .
