Çalışmada, Türkiye'nin Akdeniz Bölgesi'nden toplanan balık örneklerinde ⁷Be, ⁴⁰K, 134,137Cs, ²²⁶Ra, ²³⁵U ve ²³⁸U radyonüklidlerinin konsantrasyonları ölçülmüştür. Elde edilen sonuçlar, farklı balık türlerinde çeşitli radyonüklidlerin varlığını ortaya koymuştur: Pagrus pagrus türünde ²³⁵U, ²³⁸U ve ²²⁶Ra; Scomber scombrus türünde ²³⁸U ve ²²⁶Ra; Sarda sarda türünde ²³⁵U ve ²²⁶Ra; Spicara smaris ve Sardina pilchardus türlerinde ²³⁸U; Mullus barbatus türünde ²²⁶Ra; Mugil cephalus türünde ²³²Th; ve Dicentrarchus labrax türünde ise ⁷Be tespit edilmiştir. Tüm türler için hesaplanan yıllık etkin doz (AED) değerleri, Uluslararası Radyolojik Koruma Komisyonu (ICRP) tarafından önerilen 1000 μSv/yıl güvenlik eşiğinin oldukça altında kalmıştır. Bu nedenle, Türkiye'nin Akdeniz Bölgesi'nden elde edilen bu balık türlerinin tüketiminin, önemli bir radyolojik, çevresel veya sağlık riski oluşturmadığı sonucuna varılabilir.

Radiological and Environmental Risk Assessment of Fish Samples from the Mediterranean Waters of Türkiye

Öz

In this study, the concentrations of radionuclides ⁷Be, ⁴⁰K, 134,137Cs, ²²⁶Ra, 235,238U, were measured in fish samples collected from the Mediterranean Region of Türkiye. The results revealed the presence of various radionuclides in different fish species 235,238U and ²²⁶Ra in Pagrus pagrus; ²³⁸U and ²²⁶Ra in Scomber scombrus; ²³⁵U and ²²⁶Ra in Sarda sarda; ²³⁸U in Spicara smaris and Sardina pilchardus; ²²⁶Ra in Mullus barbatus; ²³²Th in Mugil cephalus; and ⁷Be in Dicentrarchus labrax. The calculated annual effective dose (AED) values for all species were substantially below the 1000 μSv/year safety threshold recommended by the International Commission on Radiological Protection (ICRP). Therefore, it can be concluded that the consumption of these fish species from the Mediterranean Region of Türkiye does not pose any significant radiological, environmental, or health risks.
