The study referred to determine the possible radiological risks by the help of internationally approved health hazard indices derivated by field and laboratory gamma measurements performed for surface, adit and core samples from Gabal Abu Dabbab albite granite Ta-Nb-Sn mining area, which is located some 50 km northwestern Marsa Alam city within the central Nubian Shield of Egypt. The field measurements were taken by portable RS-230 γ-ray spectrometer and the laboratory spectrometric analyzes were verified by HPGe detector for the radioactivity measurements of 238U, 226Ra, 232Th and 40K (Bq/kg) in the studied samples to assess their radiation hazards. Statistical depicting groups, summary statistics and two sample comparison tests (t-test and Mann-Whitney test) were used for statistical evaluations. The gamma-ray radioactivity levels of surface samples maximized to 94.68, 61.64, 45.10 and 1051.62 Bq/kg for 238U, 226Ra, ³²Th and ⁴⁰K respectively, whereas adit samples reached to 206.47, 113.16, 198.7, 939.43 Bq/kg and core samples reah to 108.23, 54.17, 43.47, 939.42 respectively. Almost values of the radiation hazard indices in the studied samples were under the health hazard limits
