Özet

The Po-210 radionuclide concentrations of some marine organisms (Eriphia verrucosa, Solea solea, Mytilus galloprovincialis, Ulva lactuca) obtained from the northern part of the Sea of Marmara (Tekirdag) in 2019 are presented in this study. The spontaneous radiochemical processes for Po-210 deposition in these marine species were performed by using three various metal discs. The Po-210 deposition yields of different species on silver, stainless steel and aluminium discs was investigated, and then, the disc with the best chemical deposition yield was determined. The Po-210 activity concentrations of E. verrucosa samples were measured to be 6.3 +/- 0.8 Bq kg(-1) on silver disc, 5.9 +/- 1.4 Bq kg(-1) on stainless steel disc and 3.4 +/- 2.1 Bq kg(-1) on aluminium disc. The Po-210 activity concentrations of S. Solea on silver, stainless steel and aluminium discs were found to be 15 +/- 2 Bq kg(-1), 11 +/- 3 Bq kg(-1) and 4.8 +/- 2.4 Bq kg(-1), respectively. The Po-210 specific activities of M. galloprovincialis samples taken in port for silver, stainless steel and aluminium discs were 39 +/- 4 Bq kg(-1), 23 +/- 8 Bq kg(-1), and N.M. (not measurable), respectively. Also M. galloprovincialis samples collected outside the port had the Po-210 concentrations of 57 +/- 6 Bq kg(-1) and 21 +/- 8 Bq kg(-1) on silver and stainless steel. While the Po-210 concentrations for out of port U. lactuca U. lactuca samples were found to be 60 +/- 6 Bq kg(-1) for silver, 49 +/- 12 Bq kg(-1) for stainless steel and 39 +/- 15 Bq kg(-1) for aluminium, the 210Po concentrations for in port U. lactuca on silver were determined to be 19 +/- 3 Bq kg(-1). The annual effective ingestion doses from the consumption of E. verrucosa, S. solea, M. galloprovincialis and U. lactuca species were also calculated.
