Measurement of radioactivity levels of liquid milk samples in Kütahya, Turkey

Abstract

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
