Evaluation of Gross Alpha and Beta Radioactivity Concentrations in Tooth Samples
Abstract
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.
