DOI : 10.23893/1307-2080.APS.05729 In Natural radioactive materials may be existing in the environmental substances that have uses in pharmacy and medicine as health supplements. In this study, natural radionuclides such as 226Ra, 232Th, and 40K were measured in seven medicinal or herbal plants collected from the local market in Kars, Turkey were analysed. All samples were analysed by means of gamma-ray spectrometer using NaI(Tl) detector. The radioactivity concentrations were found to vary in the range of 16.39±2.2 to 32.76 ±3.5 Bqkg-1 for 226Ra, 19.74±3.7 to 85.01±5.6 Bqkg-1 for 232Th, and from 795.82±9.8 to 1056.28±14.4 Bqkg-1 for 40K. Rosehip showed the lowest activity concentrations of 226Ra, 232Th and 40K, while rumex patientia showed the highest activity concentration of 40K. In this research study, we aimed to determine the activity concentrations of radionuclides in medicinal plants and provide useful information to carry out a dose assessment to be exposed to people using medicinal plants for healing various diseases.
