Egorova I.N., Neverova O.A. ASSESSMENT OF RADIONUCLIDE POLLUTION MEDICINAL RAW MATERIALS ACHILLEA MILLEFOLIUM L., UNDER CONDITIONS OF WASTE DUMP AT KEDROVSKY COAL MINE ASSESSMENT OF RADIONUCLIDE POLLUTION IN FRUITThe article presents the estimation of radionuclide pollution of medicinal plant materials (herbs, flowers) Achillea millefolium L., growing on the waste dump of the Kedrovsky coal mine the Kemerovo region, and the estimation of complementary embryonic soils in matter of natural (K-40, Th-232, Ra-226) and artificial (Sr-90 and Cs-137) radionuclides. Analysis of the results showed no contamination of the embryonic soils dumps artificial radionuclides. The content of Sr-90 and Cs-137 is substantially below the regional average. The level of natural radionuclides is within the background levels of radioactive elements in the earth's crust. The analysis also revealed that the content of natural (K-40, Th-232, Ra-226) and artificial (Sr-90 and Cs-137) radionuclides in embryonic soils is higher than in medicinal plant material Achillea millefolium L.. the Main contribution to the radioactivity of raw materials gives K-40, it accounts for grass — 81 %, for flowers — 76 % of the total radioactivity. The proportion of artificial radionuclides Sr-90 and Cs-137 in grass and flowers of Achillea millefolium L. is in the range of 1.02...0.458 Bq/kg, not to exceed the allowable levels and do not present a hazard to the health of consumers according to SanPiN 2.3.2.1078-01. Analysis of rates of accumulation grass and flowers of Achillea millefolium L. radionuclides showed that they are more likely to accumulate anthropogenic radionuclide group Sr-90 and Cs-137. However, KN is less than one and are in the range of 0.56...0.41, which indicates the absence of data accumulation of radionuclides by plants. The obtained data will allow to assess the possibility of using medicinal plants growing on anthropogenically altered the Kemerovo region and get new resource sources and for harvesting of medicinal raw materials for the needs of the region.Key words: Achillea millefolium L., medicinal plant raw material, radionuclides, recultivated lands, waste rock dumps.
