Radionuclide Content in Black Sea Sediments from Varna Bay at the Northern Bulgarian Coast – Tz. Nonova, K. Slavova, I. Genov, L. Dobrev, V. Doncheva, O. Hristova, B. Dzhurova

This work presents data on the accumulation of technogenic 137Cs and natural radionuclides of the 238U and 232Th series (238U, 226Ra, 232Th) and 40K in Black Sea sediments collected from Varna bay at the Northern Bulgarian Black Sea coast. The aim of the study is to be the first step in a future large study of the content of radionuclides in sediments from different geographical areas along the whole Bulgarian coast.
Keywords: radionuclides, coastal sediments, sea water, Black Sea.
