Herbal teas are an important part of traditional medicine in Serbia. The objective of the present study was to determine the activity concentrations of (40)K and (137)Cs in herbal tea, using the gamma spectroscopy method. The samples were collected during the period 2011-2012 in three mountain regions in Western and Central Serbia. The activity concentrations of (40)K and (137)Cs were found to be in the range of 130-1160 and 0.7-124 Bq kg(-1), respectively. The average annual effective dose equivalents from ingestion of (40)K and (137)Cs for an adult person consuming one cup of herbal tea daily were found to be 588.4-5250.2 nSv for (40)K and 4.0-706.1 nSv for (137)Cs. Our investigation showed that the herbal teas originating from Maljen, Zlatibor and Tara mountains are radiologically safe for human consumption.
花草茶是塞尔维亚传统医学的重要组成部分。本研究的目的是使用伽马能谱法测定花草茶中（40）K和（137）Cs的活度浓度。样本于2011年至2012年期间在塞尔维亚西部和中部的三个山区采集。发现（40）K和（137）Cs的活度浓度分别在130 - 1160 Bq kg(-1)和0.7 - 124 Bq kg(-1)范围内。对于每天饮用一杯花草茶的成年人，摄入（40）K和（137）Cs的年均有效剂量当量分别为（40）K的588.4 - 5250.2 nSv和（137）Cs的4.0 - 706.1 nSv。我们的调查表明，源自马尔耶恩山、兹拉蒂博尔山和塔拉山的花草茶对人类消费而言在辐射方面是安全的。
