Use GIS technical to map natural radioactivity in soil samples for the University of Kufa, Iraq
GIS "Geographic Information System" technology was used to map the specific activity (S.A.) of primordial radionuclides 238U, 232Th, and 40K in selected soil samples for twelve locations at the University of Kufa, Iraq. S.A. values were determined using gamma spectrometry type NaI(Tl) with volume “3 × 3”. Also, the values of radiological parameters such as Raeq "radium equivalent", Hex "external hazard index", Iγr "representative gamma risk index", Dr "Absorbed Dose rate", AEDEoutdoor "Annual Effective Dose Equivalent in outdoor", and ELCR "Excess Lifetime Cancer Risk" were determined. The average value of S.A. for 238U, 232Th, and 40K was 10.35 ± 0.9 Bq/kg, 7.31 ± 1.8 Bq/kg, and 256.19 ± 55.7 Bq/kg, respectively. While, the average values of Raeq (Bq/kg), Hex, Iγr, Dr (nGy/h), AEDEoutdoor (mSv/y), and ELCR were 48.00, 0.130, 0.373, 23.70, 0.029, and 0.102 × 10−3, respectively. The results of S.A. and each radiological parameter of the study area locations were low according to acceptable level reports by UNSCEAR, ICRP, and OCDE. Therefore, it can be concluded that the soil samples of the University of Kufa were safe.
