- The natural radioactivity in soil of Nineveh Province has been studied in this paper. The radioactivity of 19 soil samples were determined by gamma spectrometry using NaI (Tl) detector .The activity of radionuclide's, 238U,232Th ,226Ra and 40K ranged from 21.25 to 58.13Bq/kg , 11.22 to 31.63Bq/kg, 17.02to 40.98 Bq/kg and from 206.51 to 509.56 Bq/kg respectively. The activity concentrations for these radionuclide's were compared with world average activity of soil, it found that the average of activity concentrations of 238U and 226Ra are higher than world average value while the activities of 232Th and 40K are found to be lower. In order to evaluate the radiological hazard of the natural radioactivity, the radium equivalent activity, the absorbed dose rate, the annual effective dose rate, internal and external hazard indices and finally, gamma index have been calculated. The study provides background radioactivity concentrations in Nineveh Province
