The specific activities of natural and artificial radionuclides in powder milk consumed by adult and infant were measured using gamma ray spectroscopy (HPGe detector). The radium equivalent activity (Raeq), internal hazard index (Hin) were also calculated together with the parameters dependent on the age group such as; annual effective dose from ingested foods (Eing), and excess lifetime cancer risk (ELCR). Five radionuclides (212Pb, 214Pb, 228Ac, 40K, 137Cs) were detected in the studied samples, with low specific activates ranged from (B. D. L) to (5.44±2.33, 2.37±1.53, 1.85±1.36, 284.87±16.87, 3.99±1.99) Bq/kg respectively, besides some samples didn’t have any radionuclide or have one only. All the calculated values are less than the average worldwide, except the annual effective dose from ingested foods. In general, the results showed good agreement with the previous studies. This is meant that the analyzed milk is safe for human consumption because their levels of radioactivity are less than the global limits.
