Özet
In this study, natural and artificial radionuclide concentrations were determined and radiological dose values of nine different medicinal plants {Sweet marjoram (Origanum majorana), Rosemary (Rosmarinus officinalis) Lavender (Lavandula x intermedia), Thyme (Thymus vulgaris), Sage (Salvia officinalis), Peppermint (Mentha piperita), Holy basil (Ocimum Sanctum), Bush basil (Ocimum minimum) and Lemon balm (Melissa officinalis)} used in Balikesir province from Turkey were evaluated. Gamma-ray spectrometry was used to determine the natural and artificial radionuclide concentrations of these medicinal plants. To evaluate radiological dose values, absorbed gamma dose rate (D), radium equivalent activity (Ra-eq) annual gonadal dose equivalent (AGDE), exposure dose (ER), annual effective dose (AED), excess lifetime cancer risk (ELCR), internal hazard index (H-in), external hazard index (H-ex) and gamma representative level (GRL) were determined. Mean values of Ra-226 and Th-232 activity concentrations are lower than the world average values, whereas mean values of K-40 activity concentrations are higher than the world average values for present medicinal plants. Lavandula x intermedia has the highest Cs-137 concentration, whilst Thymus vulgaris L. has the lowest Cs-137 activity concentration. D, Ra-eq, AGDE, ER, AED and ECLR values are the highest for Lavandula x intermedia, whilst they are the smallest for Rosmarinus officinalis L. among the studied medicinal plants. Average values of H-in and H-ex are lower than the permissible value of 1, whilst the average value of GRL is higher than permissible limit value of 1.
