Levels of 210Po and 210Pb in mussel and sediments in Candarlı Gulf and the related dose assessment to the coastal population

210Po and 210Pb in mussel (Mytilus galloprovincialis) and sediment samples collected at Candarlı Gulf during the period of 2010-2012 are presented and discussed. The activity concentrations of 210Po and 210Pb were measured by means of alpha spectrometry. Activity concentrations of 210Po and 210Pb in mussels are in the ranged of 332 ± 17-776 ± 23 Bq kg−1 dw and 14 ± 1-40 ± 5 Bq kg−1 dw, for sediments the ranges for 52 ± 5-109 ± 8 Bq kg−1 dw and 38 ± 5-92 ± 9 Bq kg−1 dw, respectively. The estimated consequent annual effective ingestion dose due to 210Po and 210Pb from mussel consumption in Candarlı Gulf coastal region were calculated. The highest dose due to 210Po and 210Po were calculated to be 4232 ± 126 μSv and 126 ± 16 μSv, respectively.
