INVESTIGATION OF RADIONUCLIDE UPTAKE BEHAVIOR AND TRANSFER FACTORS IN AGRICULTURAL SOILS AND VEGETATION OF AL-KIFIL, IRAQ

This study aimed to evaluate the activity concentrations of 238 U, 232 Th, 226 Ra, 228 Ra, and 40 K in soil and plant samples collected from different sites with varying physicochemical properties.Transfer factors (TF) from soil to plants were calculated and correlated with soil characteristics such as pH, salinity, and organic matter content.The results revealed that the highest concentrations of 238 U and 226 Ra were associated with lower pH values and higher organic matter content, while 40 K showed moderate variations between sites.These findings provide valuable insight into the behavior of radionuclides in soils with different properties and highlight the influence of soil physicochemical factors on radionuclide transfer from soil to plants.
