Abstract
Radioactivity measurements were performed, at the east (Georgia) and west (Romania) part of the Black Sea, for natural radionuclides and 137Cs in collected water and sediment samples using lab-based and in situ gamma-ray spectrometry. The activity concentrations of 137Cs at Georgian area in the sediment and seawater ranged between 20 to 50 Bq kg−1 and 8 to 25 Bq m−3, respectively while at the Romanian area the activity concentration ranged from 10 to 30 Bq kg−1 and 3 to 15 Bq m−3, respectively. The activity concentration values of 7Be at the Georgian area reached values up to (30 ± 4) Bq kg−1. The induced dose rates to marine organisms in both areas estimated by the ERICA assessment tool were much lower than the screening value of 10 μGy h−1.
