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

Abstract

(210)Po and (210)Pb 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 (210)Po and (210)Pb were measured by means of alpha spectrometry. Activity concentrations of (210)Po and (210)Pb 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 (210)Po and (210)Pb from mussel consumption in Candarlı Gulf coastal region were calculated. The highest dose due to (210)Po and (210)Po were calculated to be 4232±126 μSv and 126±16 μSv, respectively.
