Title:Mathematical modeling of radionuclide fluxes from agricultural and natural ecosystems for radiational rehabilitation of contaminated sites
Author: Zhuchenko, Yuriy Mikhailovich
Reference: Gomel, 1998
Keywords: Mathematical modeling, radionuclides’ fluxes, agricultural ecosystems, natural ecosystems, rehabilitation, land contamination
Abstract: The purpose and objectives of the research. The aim of this work is to create a universal statistical model for predicting the possibility of rehabilitation of contaminated sites based on the evaluation of radionuclide fluxes of agricultural and natural ecosystems, their influence on the formation of individual and collective radiation doses on the population and the redistribution on the territory of the district, region, and republic.

Keywords: strontium, aqueous solution, removal
Abstract: The invention relates to methods of cleaning solutions using sorption of radioactive strontium, and can be used for extraction of radionuclides strontium from solutions with high content of hardness salts and liquid radioactive wastes with complex chemical composition. The method consists of a joint process of sorption and coprecipitation of strontium on sorption-reagent materials.

Keywords: metallic waste, decontamination, melting
Abstract: The series of invention relates to the decontamination of metallic materials contaminated by radionuclides. The processing includes melting of the waste beneath the layer, above which there is an intensive recycling flow overheated in gaslift flow of slag. Thus the slag is separated from the melted metal.

Keywords: solid noncombustible surface, decontamination
Abstract: The method consists of: covering the surface layer with powdered exothermic mixture, its arson and removal of the burning radioactive products. The exothermic mixture has the following composition, wt.%: Calcium-silicon powder – 40-60, alkali metal nitrate – 2-5, industrial oil – 1-2, powder of aluminum-magnesium alloy – the rest. Results: increase of the security mode, decrease of labor intensity, increase of productivity.

Keywords: liquid waste, process, filtration
Abstract: The invention relates to environmental protection, in detail, to process of liquid radioactive wastes. The original flow of the liquid waste is subjected to be defended by the formation of supernatant liquid and sludge. The supernatant fluid is clarified with a mechanical filter to form a filtrate; the filtrate is subjected to ion-selective sorption after deep desalting in two stages.
