The activity concentrations of radionuclides in grape molasses soil samples collected from Zile (Tokat) plain in Central Black Sea region of Turkey were measured by using gamma spectrometer with a NaI(Tl) detector. Also, the concentrations of 222 Rn in soil samples and air were estimated essentially taking the activity concentrations of 226 Ra measured in soil samples. Grape molasses soil samples with calcium carbonate content are used for sedimentation for making molasses in this region. The average activity concentrations of 232 Th, 226 Ra, 40 K and 137 Cs were found as 62 ± 2, 68 ± 3, 479 ± 35 and 8.0 ± 0.3 Bq kg -1 , respectively. The average concentrations of 222 Rn in soil samples and air were estimated to be 50 kBq m -3 and 144 Bq m -3 . From the activity concentrations, absorbed gamma dose rate in outdoor air (D), annual effective dose from external exposure (E E ), annual effective dose from inhalation of radon (E I ) and excess Downloaded by [Dalhousie University] at 11:28 05 June 2016 ACCEPTED MANUSCRIPT ACCEPTED MANUSCRIPT 2 lifetime cancer risk (ELCR) were estimated in order to assess radiological risks. The averagevalues of D, E E , E I and ELCR were found to be 90 nGy h -1 , 110 Sv y -1 , 1360 Sv y -1 and 4 x 10 -4 , respectively.
Molasses, which is a traditional food substance obtained by boiling the fruit with local procedures and is abundantly eaten by Turkish people, are commonly produced from grapes. Zile, which is county of Tokat city placed in Central Black Sea region, is famous with molasses in Turkey. A special soil called as molasses soil containing CaO is added into to molasses in order to resolve acidification during production process. The purpose of this study is to determine the element concentration levels in grabe molasses soil samples collected from Zile by using energy dispersive X-ray fluorescence spectrometry (EDXRF). For this purpose, thirty-eight elements and eleven oxides were detected in molasses soil samples. The average concentrations of six major oxides (MgO, Al2O3, SiO2, K2O, CaO and Fe2O3) were found as 1.58%, 7.96%, 17.01%, 1.01%, 30.52% and 8.72%, respectively. Also, the average concentrations of three minor (Na2O, P2O5 ,TiO2) and two trace (SO3, MnO) oxides were found as 0.96%, 0.12%, 0.95% and 0.04%, 0.1%, respectively.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
