Özet:

 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 17.90.5 Bqkg, 14.10.4 Bqkg and 445.28.0 Bqkg, 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 0.440.01 and 0.780.06, transfer factors calculated for 232Th radionuclide transfer were between 0.360.02 and 0.790.06 and transfer factors calculated for 40K radionuclide transfer were between 0.240.02 and 0.700.08. 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.

 Bu çalışmanın amacı, Malatyadaki tarım arazilerinde ve bu arazilere dikilen kayısı ağaçlarının meyvelerinde doğal radyonüklid konsantrasyonlarını ve bu radyonüklidlerin topraktan taze kayısıya transfer faktörlerini TF belirlemektir. Ayrıca, kayısının tüketilmesi sonucunda maruz kalınacak yıllık etkin sindirim dozunu AEingest ve oluşabilecek kanser riskini LCR de belirlemektir. Çalışmada, 226Ra, 232Th ve 40K radyonüklidlerinin toprak örneklerindeki ortalama konsantrasyonları sırasıyla 17,9  0,5 Bqkg, 14,1  0,4 Bqkg ve 445,2  8,0 Bqkg olarak hesaplanmıştır. Toprak örnekleri için hesaplanan 226Ra ve 232Th aktivite değerleri sınır değerlerin altında bulunurken, 40K için hesaplanan değerler T-2, T-4 ve T-10 hariç sınır değerlerin üzerinde bulunmuştur. Tarım arazilerindeki kayısı örneklerine topraktan geçen 226Ra radyonüklidi için hesaplanan transfer faktörleri 0,44  0,01 ile 0,78  0,06 arasında, 232Th radyonüklid geçişi için hesaplanan transfer faktörleri 0,36  0,02 ile 0,79  0,06 arasında ve 40K radyonüklid geçişi için hesaplanan transfer faktörleri ise, 0,24  0,02 ile 0,70  0,08 arasında değişmektedir. Tüm TF değerleri 1den küçük bulunmuştur. Çalışmada, AEingest ve LCR hesaplamaları sonucunda elde edilen sonuçların ve ortalamaların izin verilen sınır değerlerin altında olduğu görülmüştür.
