“…Natural radioactive isotope values are determined by the physical, chemical, and biological properties of the soil. Natural radioactive isotopes are increased by rainfall, different types of cultivated plants, soil management techniques, and the use of fertilizers [2]. The most important terrestrial radionuclides to consider are 238 U, 232 Th, and 40 K because they are abundant in the Earth's crust and have a long half-life [3].…”

Soil samples were collected from various regions of Baghdad, Iraq's capital, and the activity concentration was determined using a high-purity germanium (HPGe) detector. The average activity concentrations of 226Ra, 232Th,) Bq/Kg, (11.13-12.00) Bq/Kg, and (108.12-213.45) Bq/Kg, respectively. Radium equivalent activity, internal and external hazard indices, air absorbed dose rate, and annual effective doses have been calculated to find the radiological effects. The parameters were found to be less than the reported values. As a result, the radioactivity in the study area presents no radiological risk to the public. Finally, X-ray fluorescence spectrometry (XRF) was used to determine the concentration elements of uranium and thorium in soil samples; the average concentration elements are (11.13-12.00) with uranium and (11.13-12.00) with thorium.

Natural and artificial radioactivity of agricultural soils poses significant environmental and health risks, necessitating detailed spatial analysis and hazard assessment. This study examines the spatial distribution of natural and artificial radionuclides (NOR and Cs-137), gross α and β activity, and in situ dose rates in agricultural soils through statistical and geostatistical techniques. NOR, Cs-137, and gross β activity exhibited high values and outliers, highlighting distinct distribution patterns. The Cs-137-altitude regression model consistently increased Cs-137 by 0.03 Bq/kg/m in height. Spatial distribution of natural radioactivity implies geology as a primary factor influencing the NOR distribution. However, analysis of spatial clusters and outliers unveiled geochemical variability for Ra-226 and Th-232, while the K-40 distribution appeared spatially random, potentially linked to agricultural activity. Additionally, a significant disparity in the distribution of K-40 by land use was identified, potentially attributable to potassium fertilizer application. Despite variability, average NOR values (394 Bq/kg for K-40, 22.5 Bq/kg for Ra-226, and 24.8 Bq/kg for Th-232) fall within UNSCEAR ranges. Gamma-emitting radionuclide-induced doses and risk primarily impacted nonresidential areas. These findings can be used in land use decisions, guide the development of contamination mitigation strategies to ensure safe agricultural practices, and help predict areas at risk of higher contamination for targeted remediation efforts.
