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

Abstract

Po-210 and Pb-210 in mussel (Mytilus galloprovincialis) and sediment samples collected at Candarli Gulf during the period of 2010-2012 are presented and discussed. The activity concentrations of Po-210 and Pb-210 were measured by means of alpha spectrometry. Activity concentrations of Po-210 and Pb-210 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 Po-210 and Pb-210 from mussel consumption in Candarli Gulf coastal region were calculated. The highest dose due to Po-210 and Po-210 were calculated to be 4232 +/- 126 mu Sv and 126 +/- 16 mu Sv, respectively. (C) 2013 Elsevier Ltd. All rights reserved.
