Özet: All living creatures in nature are constantly exposed to ionizing radiation, which is emitted from natural and artificial radiation sources. For this reason, it is important to monitor the levels of radioactivity in living spaces and visited areas. In this study, 226Ra, 232Th, 40K and 3H concentrations in water samples taken from Ovit Dağbaşı Lake located on İkizdere-İspir highway in İkizdere district of Rize province were determined using a high purity germanium detector and a liquid scintillation counter. It was determined that 226Ra, 232Th, 40K and 3H radioisotope concentrations in the water samples varied between 0.36-2.82 Bq/L, 0.37-1.92 Bq/L, 13.28-20.96 Bq/L ve 2.51-3.53 Bq/L, respectively. Mean radioactivity concentrations were found as 1.80±0.54 Bq/L for 226Ra, 1.13±0.51 Bq/kL for 232Th, 17.22±2.61 Bq/L for 40K and 2.88±0.47 Bq/L for 3H. The activity concentrations found were compared with the values recommended by international organizations and were found to be lower than the recommended values except for the 232Th radioisotope. As a result, it has been shown with this study that the radioactivity caused by the examined radioistopes will not pose a health risk for the visitors of Ovit Dağbaşı Lake.
