Abstract:

 The specific activities of the natural radionuclides U-238 and Th-232 and K-40 in 14 soil samples collected from different sites fromAL-Mustansiriyah university at two depths (topsoil "surface" and20cm depth) were be investigated using gamma ray spectrometer3"x3" NaI(Tl) scintillation detector.The analysis of the energy spectra of the soil samples show thatthese samples have specific activities ranging with (16.08-51.11)Bq/kg for U-238, (14.79-52.29) Bq/kg for Th-232 and (191.08-377.64) Bq/kg for K-40, with an average values of 29.37, 34.14 and289.62 Bq/kg for U-238, Th-232, k-40 respectively. The radiationhazard parameters of the natural radionuclides; radium equivalentactivity (Raeq), gamma absorbed dose rate (Dγ), annual effective doserate (Eγ), internal and external hazard index (Hin, Hex) have also beencalculated. The maximum value of specific activities and hazardparameters was found in the sample of the soil gathered from theLiterature college center. All the calculated specific activates valueswere be in the ranges of worldwide averages, and below than theglobal permissible limits, this would indicate that the soils of theUniversity is safety for both students and staff.
