Tell al-Hiba is one of the most important ancient Sumerian sites, dating back to 1950 BC. This site is famous for having temples and places where priests lived, in addition to being an important economic site in that period. In the present study, the natural radioactivity concentrations of radionuclides were measured for building materials samples, collected from this site. Ten samples were collected from different kinds of building materials used in the building of houses and places of worship. A 3”x3” NaI (Tl) gamma-ray spectroscopy system was used. The results of the measurements showed that the specific activity of 92U 238 , 90Th 232 , 88Ra 226 , and 19???? 40 is ranged (from 9.57- 36.57Bq/kg) with an average of (20.1Bq/kg), (8.31- 21.49Bq/kg) with an average of (15.99Bq/kg), (8.19 - 29.18Bq/kg) with an average value of (17.71Bq/kg), and (100.37 - 288.9 Bq/kg) with an average value (195.37Bq/kg) respectively.
