Radionuclide Content in the Soil-Water-Plant-Livestock Product System in East Kazakhstan

摘要

In this study the concentration of radionuclides (Cs-137, Am-241, and Pu-239/240) in different types of environmental samples and livestock products were determined. The samples of soil, plants, water, milk, and meat from five stationary control points belonging to the zone of radiation risk situated near Semipalatinsk Test Site in Kazakhstan were collected. The concentrations of radionuclides were determined by alpha- and gamma-spectrometry. Results about the content were discussed. The levels of radionuclides did not exceed the maximum contaminant levels. The most contaminated samples were soil (Cs-137: 2,100.0 and 1,380.0 Bq/m, Am-241: 2,220.037 and 900.015 Bq/m, and Pu-239/240: 567.0 and 372.0 Bq/m) and plants (Cs-137: 0.3 and 2.2 Bq/kg) from the Sarzhal and Kainar regions.
