Radioecological study of several herbs

Full text: Comparative radiological study of herbs being on the sale of city's drug stores which were collected from the areas contaminated with radioisotopes belonged to the great semi-split period at the result of Chernobyl catastrophe with the similar herbs typical to our Republic have been carried out. The study has found that the level of beta radioactivity contained in Radix unulae was tree times higher than local norms while Cormus Ledi represented about 10 times and Cortex Quercus 4 times higher proportion of beta radioactivity. Also radioactivity of Radix unulae growing in the local conditions was different from the norm which showed 12 times higher radioactivity comparing with other herbs. It was revealed that both gamma and beta radioactivity of other local herbs are meet the norms, except Radix inulae and Glycyrrhiza glabra. The study determined that the radioactivity on the leaf of clycyrrhiza glabra was in the norm while the trunk represented approximately 2 times and the root 10 times higher radioactivity. The overall study of clycyrrhiza glabra showed that radionuclides are mostly concentrated in the peel of the root, which has slightly differences from the acceptable norms in the peel. Finally, the radiation abnormality observed in Radix inulae and Clycyrriza glabra must be in the focus of their producers and users
