Abstract
The radiological hazard that resulting by using of some chemical fertilizer kinds in Egypt have beendetermined.In this study gamma spectrometry (HPGe) detectorwas employed in order to measuring amounts of natural radionuclides ( 226Ra, 232Th  and 40K) . The output average activity concentrations of ,  and were 2.9 ± 0.9 to 3060 ± 562  , 4.7 ± 1.6 To 277 ± 43.1 and 15 ± 2.1 to 806 ± 259 ,respectively.We calculated the radiological hazards each of, radium equivalent activity (Raeq ),external (Hex ) and internal (Hin) indices and annual effective dose due to the existent of these radionuclides in  the selected samples. The obtained results were compared with the reported data from  other countries.
