In the present work, the specific activity of radionuclides such as 238U, 232Th, and 40 K for selected of agriculture soil and rice samples collected from Al-Abbasiyah City, Al-Najaf Governorate, Iraq, was measured using NaI(Tl) detection system. Also, the transfer factors of the radionuclides detected from soil to rice samples were determined. As it was done, radiological impact parameters due to radionuclide in all samples of the present study were calculated. The average values of specific activity of 238U, 232Th, and 40 K found in soil samples were 26.63 ± 9.39 Bq/kg, 13.76 ± 3.52 Bq/kg, and 598.81 ± 150.48 Bq/kg, respectively, while in rice were 14.17 ± 6.57 Bq/kg, 6.59 ± 3.13 Bq/kg, and 216.63 ± 131.82 Bq/kg, respectively. Also, the average values of the transfer factor of 238U, 232Th, and 40 K were 0.55 ± 0.17, 0.47 ± 0.16, and 0.35 ± 0.14, respectively. The measured activities were also analyzed based on the type of samples and collection locations. The results of 40 K in most samples of soil were high, perhaps due to the excessive use of chemical fertilizers and the geological nature of the study area. The results of radiological impact parameters in most of soil and rice were safe. The transfer factors of 23⁸U, 232Th, and 4⁰K from soil to rice are generally within the maximum permissible value determined by the IAEA and are, therefore, safe for most of the locations tested.
