Natural and artificial radionuclides in herbal teas from Serbia
Апстракт
Due to their therapeutic and pharmacologic properties, medicinal herbs have a long history of use
around the world. The objective of this study is to determine the activity concentration of natural
(
40K, 226Ra, 232Th, and 238U) and artificial (
137Cs) radionuclides in samples of herbal teas from Serbia.
The samples of the following commercially available teas: dandelion leaf (Taraxaci folium),
mulberry leaf (Mori nigrae folium), ground ivy (Glechoma hederacea), sweet wormwood (Artemisia
annua), rose hip (Cynosbati fructus), wall germander (Teucrium chamaedrys), and thyme (Thymus
vulgaris), were collected in Serbia in 2021. The radionuclides’ activity concentrations were
determined using gamma spectrometry.
The results show that among the natural radionuclides,
40K is dominant (316–1616 Bq/kg), while
the activity concentration of
226Ra and 232Th ranges from below the minimum detectable activity
(MDA) to 12.3 Bq/kg, and below the MDA to 13.4 Bq/kg, respectively. In all inv...estigated samples, the
238U activity concentration is below the MDA. Cesium-137 is detected in five out of seven analysed
samples (0.3–2.9 Bq/kg).
The results indicate that 137Cs, released into the atmosphere after the Chernobyl accident in 1986,
is still present in the environment of Serbia. Nevertheless, according to the Serbian legislation
regulating the maximum permitted levels of radionuclides in foodstuffs, all of the investigated
samples of herbal teas are safe for human consumption.
