This paper presents the results of complex radioecological monitoring of the territories, which are situated near the Semipalatinsk Nuclear Test Site, East Kazakhstan region. The radiometric measurements showed that the concentration of radon and beta particles are below the permissible levels. EROA values of a radon in rooms fluctuates from 44 Bq/m3 to 195 Bq/ m3. The measured values of fluency of betta-particles in all the studied points are less than 10 freq/ min*cm2. A specific activity of radionuclides, such as Am-241, Cs-137 and Pu – 239/240 in soils, plant, water, meat and milk were evaluated.
This article presents the results of the migration of radionuclides along the soil-water-feed-animal livestock chain in the adjacent territories of the former Semipalatinsk nuclear test site (SNTS). To analyze the radio ecological situation in the territory adjacent to the SNTS, 6 stationary control points were created, from which samples of soil, water, vegetation, and animal products were taken. The radiometric method was used to determine the radioactive background of the studied areas. Gamma-, alpha-spectrometry methods were used to study the content of radionuclides. The radionuclide transfer along the soil-water-feed-animal livestock chain was determined by a calculation method and also veterinary and sanitary examination of the beef selected from these items. The research results show that in all the test points under study the EDR values, the beta-particles flux density is below the limit of permissible values. The samples detected radionuclides as Am-241, Cs-137 and Pu-239/240 not exceeding the standards established by the Hygienic standards of the Republic of Kazakhstan. The chain of radionuclides was transferred to animal products. The organoleptic assessment of the quality of cattle meat showed that inconsistencies are observed: a slight increase in lymph nodes, muddy broth, and surface moisture of muscle.
Due to high prevalence of the Parascaris equorum among horses, the effect of Paracardiosis infestation on nutritional and biological values of meat is required. In an effort to analyze the radionuclides contents, biochemical parameters and biological value of horsemeat collected from different areas of Semipalatinsk Nuclear Test Site (SNTS) of Kazakhstan. The prevalence of parascaridosis was performed following standard protocols. Organoleptic properties, chemical composition, amino acids composition, vitamin contents of meat collected from zone of extreme radiation risk, zone of maximum radiation risk, zone of increased radiation risk and zone of minimum radiation risk were appraised following previously reported standard assays. pH indicators, reaction to peroxidase enzyme, formolic reaction and bacterioscopy of fingerprints were done. Contents of essential minerals were also compared. Specific radioactivity of radionuclides in meat were Am-241 less than 0.5 Bq/kg, Cs-37 from 0.5-3.99 Bq/kg and Pu-239/240 from 0.0003-0.056 Bq/kg. The chemical composition showed that the content of protein varies from 14.2-18.7% and fat from 14.2-17.2%. In addition, the content of amino acids, fatty acids and vitamins were evaluated. Among the mineral composition, iron content was from 2705-3012 µg/100 g, copper from 178.0-195 µg/100 g and zinc from 27.7-29.5 µg/100 g, depending on the remoteness of areas from the SNTS.
