Natural and artificial radioactivity levels and hazards of soils in the Kucuk Menderes Basin, Turkey

摘要

In this study, natural and artificial radionuclide activity concentrations in surface soils of Kuecuek Menderes Basin have been measured using gamma spectroscopy. The soil samples were collected from agricultural lands in the Kiiciik Menderes Basin in Turkey. The activity concentrations of ~(226)Ra, ~(232)Th, ~(40)K and ~(137)Cs in the soils were found to be range of 12.63 ± 2.28-72.51 ± 11.23, 11.45 ± 2.4-58.12 ± 4.76, 234.8 ± 14.85-1058.52 ± 24 Bq kg~(-1) dw and 2.31 ± 0.18-7.75 ± 1.14 Bq kg~(-1), respectively. The natural gamma radioactivity of the terrestrial radionuclides in soil samples and the gamma absorbed dose rate, the annual effective dose equivalent, the radium equivalent activity, the external hazard index, were calculated and compared with the international recommended values.
