Total nitrogen fat and dampness parameters were determined. Nitrogen levels are 16.925 total (N)% in Zeytinalani, 14.96 total (N)% in Karantina, 17.63 total (N)% in Iskele, 13.72 total (N)% in Balikhova and total 13.13 (N)% in Karaburun. Activity of 137Cs, 40K, 226Ra, 228Th and gross gamma radioactivities of the samples were determined using a well type scintillation gamma spectrometer. The content of 137Cs, 40K, 226Ra, 228Th radioactivity varies from 10 to 20 Bq/kg, 354 to 489 Bq/kg, 0.36 to 0.62 Bq/kg and 0.14 to 0.37 Bq/kg respectively.eninfo:eu-repo/semantics/closedAccessMarine shellsProtein sources from seaRadioactivityArticle609.Oct550559N/A
