摘要

这项研究的目的是确定塞尔维亚市场上常见食品的13种不同样品中的天然和人工放射性水平。用伽马能谱法测定了226Ra、232Th、40K和137Cs的活度浓度。成年人每年因饮茶而受到的137Cs和天然放射性核素的全身剂量为:137Cs为2.3 - 8.5 nSv, 232Ra为14.1 - 21.7 nSv, 232Th为18.4 - 73.6 nSv, 40K为10.4 - 22.9 nSv。这些剂量对一般公众的健康没有危害。

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.
