BaselineActivity levels of 210Po and 210Pb in some fish species of the Izmir Bay (Aegean Sea)

Concentrations of 210Po and 210Pb were determined in the edible muscle tissue of twelve species of marine fish collected from Izmir Bay in the Aegean Sea Region of Turkey during the 2006-2007. 210Po activity concentrations in fish samples were found to vary from ND to 400 ± 9 Bq kg−1 dry weight and 210Pb activity concentrations were found to vary from ND to 15 ± 3 Bq kg−1 dry weight. The highest dose contribution due to 210Po to humans was found to be 8.908 μSv y−1.

► This study was determined the 210Po and 210Pb levels in the fish. ► Different fish species were collected from Izmir Bay (Aegean Sea). ► Higher 210Po and 210Pb concentrations were found in Sardine. ► The annual dose from the consumption of the fish samples was calculated. ► The ingestion dose was found in the range 0.044-8.908 μSv y−1.
