Reference: Gazette “РАДИАЦИОННАЯ БИОЛОГИЯ. РАДИОЭКОЛОГИЯ “ (Radiation Biology, Radioecology), 2007

DOI: 10.1134/S0869803107040091

ISSN: 0869-8031

Keywords: 137cs, 90sr, pine plantation, radionuclides, soil

Abstract: Investigation of the distribution of 137Cs and 90Sr in pine plantations in different edaphic conditions. Confirms that the stock of radionuclides in the forest litter depends on the range of the contamination and varies from 10 to 70% for 137Cs and 20 to 60% for 90Sr. With increasing moisture in soil, in each gradation of trophic network, increases R 137Cs in wood and reduces 90Sr.  The stock of 137Cs and 90Sr in the wood of pine plantations in various edaphotopes depends on state of plantation and the levels of accumulation of radionuclides.

Imitation Model of 90Sг Behavior in the Soil and Stand of Pine Forest

 

Author:  Mamikhin S. V., Nikulina M. V.

Reference: Gazette “РАДИАЦИОННАЯ БИОЛОГИЯ. РАДИОЭКОЛОГИЯ “ (Radiation Biology, Radioecology), 2005

ISSN: 0869-8031

Keywords: forest radioecology, 90sr, vegetation, soil

Abstract:The algorithm of display of 90Sr’s behavior mechanism in forest ecosystems by method of imitating modeling is developed. Distinctive features of algorithm: the 90Sr contents in vegetation is subdivided into two parts (outside and internal pollution), whose dynamics is considered separately; dynamics of radionuclide is considered in connection with dynamics of organic substance; it is supposed, that 90Sr’s behavior in plants is similar to Ca behavior; the biological availability 90Sr contained in a soil, is integrated function of time and physico-chemical properties of the given soil. On the basis of offered algorithm the model is constructed which is used for realization of a number of numerical experiments, including reconstruction of a situation of pollution of forest ecosystem on grey forest soils in result of Kyshtym accident. The quantitative estimations of intensity of 90Sr redistribution between stand components and soil are received. The modern problems of creation of prognostication models of 90Sr dynamics in the forest ecosystems are discussed.

Modeling of long-term transformation of 90Sr forms in soils

Author: A.V. Konoplev

Reference: Nauka, 2005

ISSN: 0032-180x

Keywords: strontium, soil

Abstract: A model of long-term transformation of the forms of 90Sr  (strontium) in soil, and obtained estimates of parameters. Comparative analysis of the forms of soil in a stable and radioactive strontium showed that the fixation of 90Sr occurs in two stages. The characteristic time of the second stage of fixation is about 100 years long.

Keywords:Thermoluminescent dosimeter; External dose rate; ERICA; Plutonium; Caesium; Strontium; Small mammals; Chernobyl

Abstract: An essential step in the development of any modelling tool is the validation of its predictions. This paper describes a study conducted within the Chernobyl exclusion zone to acquire data to conduct an independent test of the predictions of the ERICA Tool which is designed for use in assessments of radiological risk to the environment.
