CS-137 and CS-134 content in the fish of the Neum – Klek Bay

Abstract

       This paper gives the survey of the content of the fission radionuclides Cs-137 and Cs-134 in the sea fish of the Neum-Klek Bay. Fish samples equaled 5 kg. Gammaspectrometric measurement was performed with high resolution (1.95 KeV) and 25% efficiency HPG detector connected to the 4096-channel analyzer and computer.

      Analysis of results shows the presence of both fission radionuclides (Cs-137 and Cs-134) in all tested samples. The Cs-137 concentration ranges from 0.16 to 1.90 Bq/kg and the Cs-134 concentration from 0.08 to 0.28 Bq/kg.
