Abstract :Agricultural researchers in many countries investigate radiological risks in soil and crops because it concerns human health. In addition, they also study heavy metal pollution in plants in cultivated soil for ecological safety. This study aims to analyze the activity concentrations of radionuclides and heavy metals in soil and corn crops in the Küçük Menderes Basin insert ignore into journalissuearticles values(Izmir, Turkey); – which is enriched with phosphatic fertilizers. We collected soil and corn samples from the area, and then separately measured concentrations of radionuclides insert ignore into journalissuearticles values(226Ra, 232Th and 40K); and trace elements insert ignore into journalissuearticles values(Cd, Cr, Cu, Hg, Ni, Pb and Zn); they contain. Activity concentrations of the radionuclides were acquired by radiometric methods insert ignore into journalissuearticles values(gamma spectroscopy);. Heavy metal amounts were calculated using ICP-MS insert ignore into journalissuearticles values(inductively coupled plasma-mass-spectrometry);. The mean heavy metal concentrations in the soil insert ignore into journalissuearticles values(Cd, Cr, Cu, Zn, Ni, Pb, Hg); were 0.096, 40.26, 26.51, 72.43, 32.24, 7.05 mg kg-1, 158.28 µg kg-1 and in the corn insert ignore into journalissuearticles values(Cd, Cr, Cu, Zn, Ni, Pb, Hg); were 0.01, 1.09, 2.05, 22.00, 0.54, 0.24 mg kg-1, 12.15 µg kg-1. The heavy metal concentrations in soil samples were as follows: Hg Keywords : Radioecology, agronomy, heavy metals, soil, corn
