Health risk assessment of natural and artificial radionuclides in medicinal plants

In the present work, we determined activity concentrations of ten Medicinal herbs using gamma spectrometry. The radioactivity concentration 226 Ra, 232 Th, 40 K and 137 Cs were 2.82, 0.63, 984.32, 0.28 Bq/kg, respectively. These doses are not hazardous to general public's health. mean values radium equivalent (Raeq), absorbed dose rates (D), annual effective (De) external hazard index (Hex) 79.51 42.73 nGy-1 , 52.40 µSv 0.21, plants used make tea do contain a tested radionuclides that would cause negative consequences one's
