The deals with the determination of the possible radiological risks by the help of internationally approved health hazard addressed by field and laboratory gamma measurements performed for surface, adit and core samples from Gabal Abu Dabbab albite granite Ta-Nb-Sn mining area. The studied area 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 gamma-ray spectrometer and the laboratory spectrometric analyzes were verified by HPGe detector for the radioactivity measurements of U-238, Ra-226, Th-232 and K-40 (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 radioactivitylevels of surface samples reached 94.68, 61.64, 45.10 and 1051.62 Bq/kg for U-238, Ra-226, Th-232 and K-40 respectively, whereas adit samples reached 206.47, 113.16, 198.7, 939.43 Bq/kg and core samples reach 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.
