Abstract :The aim of this study was to determine the natural radionuclide concentrations and transfer factors of these radionuclides from soil to fresh apricot in agricultural lands in Malatya and in the fruits of apricot trees planted in these lands. It is also to determine the annual effective ingestion dose (AEingest) and the cancer risk (LCR) that may occur as a result of the consumption of apricots. In study, the mean concentrations of 226Ra, 232Th and 40K radionuclides in soil samples were calculated as 17.9±0.5 Bq/kg, 14.1±0.4 Bq/kg and 445.2±8.0 Bq/kg, respectively. The activity values of 226Ra and 232Th calculated for soil samples were found below limit values, while the values calculated for 40K were found above the limit values except for T-2, T-4 and T-10. Transfer factors calculated for 226Ra radionuclide transfer from soil to apricot samples in agricultural lands were between 0.44±0.01 and 0.78±0.06, transfer factors calculated for 232Th radionuclide transfer were between 0.36±0.02 and 0.79±0.06 and transfer factors calculated for 40K radionuclide transfer were between 0.24±0.02 and 0.70±0.08. All TF values were found to be less than 1. In the study, it was observed that the results and averages obtained as a result of AEingest and LCR calculations were below the permissible limit values.
