In this study, moss samples which have radiologic indicator characteristic were collected from 80 stations in Artvin to determine the natural (Ra-226, Th-232, and K-40) and artificial (Cs-137) radioactivity levels. Natural and artificial radioactivity results were observed that range activity values for Ra-226, Th-232, K-40 and Cs-137 reach the levels of <1.3 - 31.6 Bq kg(-1), <0.7 - 51.7 Bq kg(-1), 56.3 - 1100 Bq kg(-1) and <0.5 - 535 Bq kg(-1), respectively. Average values of radioactivity results were determined as 6.5 Bq kg(-1), 6.9 Bq kg(-1), 366.9 Bq kg(-1) and 26.8 Bq kg(-1) for Ra-226, Th-232, K-40 and Cs-137, respectively. Pre-determined radiologic levels in the soil samples in the study area were compared with these results. Furthermore, obtained results were evaluated with similar studies in the literature. The estimated values of unmeasured fields to determine the radiologic distribution of the study area were determined with Ordinary Kriging method, and radiologic maps were created for each radionuclide by conducting interpolated value estimation.
