The radioactivity content of 8 different types of nuts consumed in K&uuml;tahya, Turkey, was determined in 2024. </span></span></span></span><span lang="en-GB" style="font-size:9.0pt"><span style="font-family:Calibri"><span style="color:#1f497d"><span style="font-style:italic"><span style="font-weight:bold"><span style="language:en-GB">Materials and Methods: </span></span></span></span></span></span><span lang="en-GB" style="font-size:9.0pt"><span style="font-family:Calibri"><span style="color:black"><span style="language:en-GB">Fourteen nut samples collected from local markets and supermarkets in K&uuml;tahya 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&#39; Annual Effective Ingestion Dose values were estimated. </span></span></span></span><span lang="en-GB" style="font-size:9.0pt"><span style="font-family:Calibri"><span style="color:#1f497d"><span style="font-style:italic"><span style="font-weight:bold"><span style="language:en-GB">Results: </span></span></span></span></span></span><span lang="en-GB" style="font-size:9.0pt"><span style="font-family:Calibri"><span style="color:black"><span style="language:en-GB">K-40, Ra-226 and Th-232 concentrations of the samples were measured between 173.8 &plusmn; 2.7 and 305.0 &plusmn; 3.6 Bq kg</span></span></span></span><span lang="en-GB" style="font-size:5.9939pt"><span style="font-family:Calibri"><span style="color:black"><span style="language:en-GB">^-1</span></span></span></span><span lang="en-GB" style="font-size:9.0pt"><span style="font-family:Calibri"><span style="color:black"><span style="language:en-GB">, <MDA (2.6) and 3.1 &plusmn; 0.7 Bq kg</span></span></span></span><span lang="en-GB" style="font-size:5.9939pt"><span style="font-family:Calibri"><span style="color:black"><span style="language:en-GB">^-1</span></span></span></span><span lang="en-GB" style="font-size:9.0pt"><span style="font-family:Calibri"><span style="color:black"><span style="language:en-GB">, < MDA (2.6) and 3.3 &plusmn; 0.7 Bq kg</span></span></span></span><span lang="en-GB" style="font-size:5.9939pt"><span style="font-family:Calibri"><span style="color:black"><span style="language:en-GB">^-1</span></span></span></span><span lang="en-GB" style="font-size:9.0pt"><span style="font-family:Calibri"><span style="color:black"><span style="language:en-GB">, respectively. </span></span></span></span><span lang="en-GB" style="font-size:9.0pt"><span style="font-family:Calibri"><span style="color:#1f497d"><span style="font-style:italic"><span style="font-weight:bold"><span style="language:en-GB">Conclusions: </span></span></span></span></span></span><span lang="en-GB" style="font-size:9.0pt"><span style="font-family:Calibri"><span style="color:black"><span style="language:en-GB">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 &micro;Sv y</span></span></span></span><span lang="en-GB" style="font-size:5.9939pt"><span style="font-family:Calibri"><span style="color:black"><span style="language:en-GB">^-1</span></span></span></span><span lang="en-GB" style="font-size:9.0pt"><span style="font-family:Calibri"><span style="color:black"><span style="language:en-GB">, with a mean of 13.9 &micro;Sv y</span></span></span></span><span lang="en-GB" style="font-size:5.9939pt"><span style="font-family:Calibri"><span style="color:black"><span style="language:en-GB">^-1</span></span></span></span><span lang="en-GB" style="font-size:9.0pt"><span style="font-family:Calibri"><span style="color:black"><span style="language:en-GB">.
