Background: Milk is a fundamental part of the human daily diet, so radioactivity concentrations in milk must have been controlled regularly. In this study, radiation activities were measured in 12 ultra-high temperature (UHT) milk samples collected in Kütahya, Turkey, in August 2021. Materials and Methods: Radium (Ra-226), thorium (Th-232) and potassium (K-40) values were determined by using the Canberra 3x3 NaI(Tl) gamma spectroscopy method in 8 samples, and Radon (Rn-222) activity measurements have been conducted in 12 samples using the E-perm method. Results: Radium (Ra-226), thorium (Th-232) and potassium (K-40) levels are measured as < MDA (2.28 Bq/kg), < MDA (2.53 Bq/kg), 40.43 ± 2.25 to 53.31 ± 2.30 Bq/kg, respectively. Radon (Rn-222) concentrations were determined by the E-perm system between 0.46 ± 0.02 and 2.01 ± 0.05 Bq/l with an average of 1.11 ±  0.03 Bq/l. Conclusions: Annual ingested radiation doses were calculated using radioactivity levels for different age groups as a result of milk consumption. Ingestion dose levels are below the worldwide average values given in the UNSCEAR report. It has been observed that the results are below the safety limits.
Keywords: Annual effective dose, milk, radon, gamma spectrometry, natural radioactivity.
