RADIOACTIVITY ASSESSMENT OF NATURAL RADIONUCLIDES AND 137CS IN COMMONLY CONSUMED FOODS
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.
