Comparative Analysis of Containing Natural Radionuclides in the Herbs Calendula officinalis L. and Matrecaria chamomilla L.

Summary/Abstract: The healing power of many plants has been known since ancient times and it is used until nowadays all over the world. The herbs Calendula officinalis L. and Matricaria chamomilla L. are among the most commonly used herbs. The article mentions the biologically active substances and their usage in folk medicine. The content of the radionuclides in both plants and the soil, near the root system of the samples collected in June and July 2016 from the region of Yagnillo village, Varna district, has been investigated. Flowers and soil are cleaned from impurities, dried and levigated in fine powder. Gamma-spectrometric analysis was performed on the prepared samples. A low-frequency gamma-spectrometer set up by a Ge (Li) detector with multilayer protection is used. The collection of gamma-spectra was done for 86,400 s. A specialized software for gamma-spectra – ANGES – was used for their processing. The activities and specific activities of the detected natural radionuclides from the Uranium-radionuclide and Toric families are calculated. The transfer from soil to plant has been calculated. A comparative analysis of the radionuclides content in the plants and the soils on which they were grown has been made. The comparison shows qualitative and quantitative compatibility with the radionuclides found.
