Method of cleaning soil surface contaminated by strontium 90 and cesium 137

Author: A.M. Kropachev, I.I. Kropachev

Reference: Patent, 15.12.2004, Perm patent holder: Perm State University

Keywords: soil, cesium 137, strontium 90, chemical treatment, plants

Abstract: The method of cleaning consists of infusion of chemical materials into the soil. Topsoil is covered by limestone or dolomite flour (5-6 tons per hectare), with potash KCl, KNO3 or KMgCl 3.6 H2O in an amount of not less than 200 kg per hectare. This process is followed by plantation of mixture of perennial grasses, which are mowed in autumn and placed in storage, precluding the migration of radionuclides.

Estimation of radioactivity in fungal fruit bodies of the genus Leccinum fungi collected in the area of Hibiny Mountains

 

Author: Ivanov D.M., Efremova M.A.

Reference: Bulletin of St. Petersbourg University: Biology, 2012

ISSN: 1025-8604

DOI: 582.287.23:574

Keywords:  BIRCH MUSHROOMS,   ASPEN MUSHROOMS,   HIBINY,   ARTIFI CIAL AND NATURAL RADIOISOTOPES,   ACCUMULATION FACTOR, 137cs, 40k

Abstract: The article reveals that concentration of 137Cs and other radioisotopes in the fungal fruit bodies of the Leccinum genus collected in the area of Hibiny Mountains is within the limits of the admissible values. The accumulation factors of 137Cs and 40К in the fungal fruit bodies depend on soil acidity. Changes in soil рНН2О from 5,40 up to 7,33 cause a decrease of the accumulation factors of radioisotopes in fungi by more than 7 times.

Physical rationality of the universal model of radioactive depositions after the Chernobyl accident

 

Author: Ermilov A.P., Ziborov A.M.

Reference: journal “РАДИАЦИЯ И РИСК“ (Radiation and risk), 1997

ISSN: 0131-3878

DOI:

Keywords: universal model, cesium, strontium, zirconium, niobium

Abstract: A possibility of developing a universal model for the Chernobyl depositions is substantiated. The model relates radionuclides specifications and correlation ratios of activities in depositions and characteristics of preaccidental fuel and the accident circumstances. Within the model, consideration is given to two main groups of radionuclides in terms of their volatility. One group consists of non-volatile refractory radionuclides (zirconium, niobium, cerium, europium, neptunium, plutonium) and the second – radionuclides having both fuel and free activity components in the depositions (cesium, strontium, antimony, ruthenium, barium and others). The physical and chemical differences in the two deposition species dictate the search of regularities in formation of each of them, in particular deriving correlation ratios of radionuclides in the fuel and condensation components of the radioactive contamination.

Reference: Kluwer Academic Publishers-Consultants Bureau, 2006

ISSN: 1063-4258

DOI: 10.1007/s10512-006-0052-1

Keywords: 137cs, 90sr, river, lake

Abstract: The dynamics of the radioactive contamination with 137Cs and 90Sr of the Besed’ and Iput’ rivers in 1987–2004 and the nondraining Lake Svyatoe on the Besed’ River and the slowly draining Lake Kozhanovskoe in 1992–2002 is prsented. Data on the contamination of the components and shorelines of reservoirs are presented. It is shown that the radioactive contamination of these rivers is decreasing; the present level of contamination is much lower than the intervention level. The radionuclide content in the nondraining and slowly draining lakes remains high. Specifically, the 137Cs concentration in the waters of Lake Svyatoe on the Besed’ River is at the intervention level, and the 137Cs concentration in the fish in Lake Kozhanovskoe is ten times higher than the established norms.

Reference: journal “XXI ВЕК: ИТОГИ ПРОШЛОГО И ПРОБЛЕМЫ НАСТОЯЩЕГО ПЛЮС” (XXI CENTURY: PAST AND PRESENT PROBLEMS PLUS), 2012

ISSN: 2221-951x

DOI: 57.045:57.042

Keywords: 137cs, agricultural products, accumulation, soil

Abstract: The investigation of accumulation levels of 137Cs in biomass of main field crop rotation cultures (wheat, barley, potato) and of meadow ecosystems in -Plavsk radioactive spot of Tula region demonstrated that at density of radioactive pollution of soils ~200-430 кBq/m2(5-12 Ki/km2) green parts of plants accumulate 0,01-0,02 кBq/m2, and underground parts œ 0,1-3,3 кBq/m2. Accumulation 137Cs in biomass depends on biological features of vegetation, and also is in close direct dependence with accumulation of 137Cs in soils.
