“…Nuclear dust and ashes emitted in the atmosphere reach the earth's ground and plants via air or raindrops on the earth's surface, later settling on plant leaves or the soil. Rainfall and air are considered agents for radioactive fallout on the earth's surface (HIRONO and NONAKA, 2016;ZEHRINGER et al, 2018). Research studies have been conducted on soil and plant radioactivity, as well as on environment effect assessment by use of gamma-ray spectrometry.…”

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