Özet

Specific natural radionuclide (Ra-226, Th-232 and K-40) concentrations of wild and farmed European seabass collected from the Mediterranean coast of Turkey were measured and the radiological risk associated with their consumption was assessed. Gamma spectrometric measurement of radionuclide activities in the samples were performed with HPGe detector and the radiological risk associated with their ingestion was calculated over per capita fish consumption in Turkey and the EU. It was observed that the mean concentration of radionuclides activities was 4.74 +/- 0.53 Bq kg(-1) and 1.13 +/- 0.33 Bq kg(-1) for 226Ra, 2.13 +/- 0.18 Bq kg(-1) and 1.91 +/- 0.23 Bq Bq kg(-1) for Th-232, 114.36 +/- 2.86 Bq kg(-1) and 132.99 +/- 1.16 for 40K in wild and farmed seabass, respectively. The mean ingested annual radioactivity doses by wild and farmed seabass consumption were calculated as 0.71 +/- 0.02 mu Sv y(-1) and 0.82 +/- 0.01 mu Sv y(-1), respectively. From the radiological point of view, these radioactivity doses and the consumption of both wild and farmed seabass from the Mediterranean coast of Turkey do not pose any risk to the health of Turkish and EU people.
