The levels of cesium radionuclides in mosses collected from akçaabat, maçka and sürmene in the eastern black sea region of Turkey, 1997

Abstract

Radiocesium levels in mosses collected from Akçaabat, Maçka and Sürmene in the Eastern Black Sea Region of Turkey were determined 9 years after the Chernobyl accident occurred. Cs-134 and Cs-137 radionuclides were detected in all samples. The measured levels of Cs-134 and Cs-137 ranged between 28-207 and 117-8431 Bq/kg depending on moss genera and species dry weight respectively. The highest concentrations of Cs-137 were found in Anomodon viticulosus, Racomitrium lanuginosum and Leucobryum glaucum while the lowest activity was detected in Calliergon cuspidatum, Dicranum majus and Pseudoscleropodium purum.
