The aim of this study is to measure the natural radioactivity concentrations in medicinal plant samples taken from local herbal shop (46 samples) that’s are used in Jordan, but obtained from various countries. In addition, the essential, non essential and heavy metals concentrations in these samples were detected. The first part aimed to the determination of natural radioactivity concentration in medicinal plants samples using High Purity Germanium detector (HPGe). The result obtained shown that the higher concentration of Radium-226, Radium-228 and Potassium-40 in medicinal plant samples were (15.6 ± 0.46, 15.33 ± 0.1, 2034 ± 57) Bq.kg-1dry, respectively. And minimum concentration of Radium-226, Radium-228 and Potassium-40 in medicinal plant samples were (0.26 ± 0.05, 1.47 ± 0.5, 24 ±1.6) Bq.kg-1dry.
Key words: Natural Radioactivity; Medicinal Plants; (HPGe) Detector; (ICP-MS) Spectroscopy.
