Abstract :Objective: Teeth are used as an important data source to estimate radioactivity accumulation in individuals. This study aimed to evaluation the gross alpha (GA) and gross beta (GB) radioactivity concentrations in tooth samples. Methods: Mandibular permanent first molar teeth of individuals living in the Middle Black Sea region were used for the study to ensure standardization. The teeth samples were divided into 4 groups according to the age factor (Group 1: 6-15 years, Group 2: 16-30 years, Group 3: 31-45 years, and Group 4: 46-65 years). Each group was divided into two subgroups according to gender factor. Measurements were completed with a nuclear spectroscopic system containing a gas-flow proportional counter. Data were analyzed statistically. Results: While a statistically significant difference was detected among groups for GA radioactivity concentration (p<0.05), no significant difference was detected among groups for GB (p>0.05). Mean GA value was higher in Group 1 (6-15 years) compared to the other groups. There was no statistically significant difference between the genders in both GA and GB radioactivity concentrations for all groups (p>0.05). Conclusion: While the GA radioactivity concentration was affected by the age factor, it was not affected by the gender factor.
