Descriptive statistics and risk assessment for the control of seasonal pollutant effects of 210Po and 210Pb in coastal waters (Çanakkale, Turkey)

Determinations of 210Pb contents in food, diet, environmental samples and estimations of internal dose due to daily intakes

²¹⁰Pb in food, diet and environmental samples collected in China during the period of 2015-2017 was analyzed and discussed in this study. The activity concentrations of ²¹⁰Pb were measured by gamma spectrometry, the average of which in sea food, cereal, mushroom, duplicate diet, soil, sediment, biomass ash and aerosol samples were 1.22 ± 0.69 Bq kg^-1 fresh weight, 2.77 ± 0.33 Bq kg^-1 fresh weight, 8.2 Bq kg^-1 dry weight, 1.21 Bq kg^-1 dry weight, 172 ± 44 Bq kg^-1 dry weight, 87.2 ± 39.2 Bq kg^-1 dry weight, 140 ± 185 Bq kg^-1 and 813 ± 520 μBq m^-3, respectively. The results were higher than those observed in various countries except for seafood. The annual effective dose due to mushroom, duplicate diet and aerosol were estimated. Furthermore, the transfer factor (TF) of ²¹⁰Pb from soil to some species of mushroom were also considered. This study provided useful data for radiation protection of the public.
