Background: Nuts are nutrient-rich foods and are recommended to be promoted to the public for their immense health benefits. The radioactivity content of 8 different types of nuts consumed in Kütahya, Turkey, was determined in 2024. Materials and Methods: Fourteen nut samples collected from local markets and supermarkets in Kütahya province were pulverized and dried, then waited in a 1 L Marinelli container for 30 days to attain equilibrium between Ra-226 and Th-232, their daughter products, finally sample content is determined using Canberra 3x3 NaI (Tl) detector. In addition, the samples' Annual Effective Ingestion Dose values were estimated. Results: K-40, Ra-226 and Th-232 concentrations of the samples were measured between 173.8 ± 2.7 and 305.0 ± 3.6 Bq kg-1, <MDA (2.6) and 3.1 ± 0.7 Bq kg-1, < MDA (2.6) and 3.3 ± 0.7 Bq kg-1, respectively. Conclusions: The annual effective ingestion dose resulting from nut consumption was calculated assuming that an adult consumes 20 g of dried nuts daily and found between 9.1 and 19.0 µSv y-1, with a mean of 13.9 µSv y-1. A comparison of radioactivity levels and ingestion dose results with the limits presented in the UNSCEAR report shows that they were below the safety limits. |
