ABSTRACT / САЖЕТАК:

The goal of this research is to determine the levels of natural and artificial radioactivity in 13 different samples of commonly consumed foods from Serbian markets. A gamma spectrometry was used to measure the activity concentrations of 226Ra, 232Th, 40K, and 137Cs. The annual whole-body doses from 137Cs and natural radionuclides, due to the consumption of tea for an adult, are in the range of 2.3– 8.5 nSv for 137Cs, 14.1 – 21.7 nSv for 232Ra, 18.4 – 73.6 nSv for 232Th and for 40K 10.4 – 22.9 nSv. These doses are not harmful to the general public’s health.
