Evaluation of radioactive pollution in sediment samples of Borçka Dam Lake, Turkey
Abstract
In this research, the concentrations of natural (226Ra, 232Th
and 40K) and anthropogenic (137Cs) radionuclides were measured in sediment
samples collected from the Borçka Dam Lake using a high purity germanium
detector (HPGe). The activity values ranged from 4.79-21.46, 9.36–20.65,
238.01–721.26 and 0.79–6.81 Bq kg-1 for 226Ra, 232Th, 40K and 137Cs
respectively. The average 226Ra, 232Th and 40K activity concentrations calculated
for the sediment samples were found to be lower compared to world average
values reported by UNSCEAR. In addition, radiological hazard indices were
determined and compared with the international permissible values. The results
of this study revealed that there is no significant health risk for people
exposed to sediment samples in this region.
