abstract = "Herbal teas are an important part of traditional medicine in Serbia. The objective of the present study was to determine the activity concentrations of K-40 and Cs-137 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 K-40 and Cs-137 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 K-40 and Cs-137 for an adult person consuming one cup of herbal tea daily were found to be 588.4-5250.2 nSv for K-40 and 4.0-706.1 nSv for Cs-137. Our investigation showed that the herbal teas originating from Maljen, Zlatibor and Tara mountains are radiologically safe for human consumption.",
