Sayan Salmenbayev and Nurlan Mukhamediyarov, specialists of NNC RK, took part in the event on invitation of organizers, reporting on: “Samaria-151 Isotopes Content Determination Method in Radioactively Contaminated Soils of Semipalatinsk Test Site” and “Chemical Composition of Water and Bottom Sediments of Uzynbulak Brook”.
Stage-by-stage process of radiochemical analysis proposed for determination of 151Sm radionuclide content in soils of the former STS was presented in the first paper. Each stage will be accompanied by evaluation of Samaria isotopes purification degree. Thus, for instance, elements distribution curves were shown in sediment-solution system, as well as purification coefficients from macro- and microelements at hydroxide sedimentation from nitrate solutions.
Second paper presented results of elemental composition study in the main components of ecosystem and physico-chemical properties of surface waters of Uzynbulak brook during different seasons of a year. Spatial and seasonal variations of hydrogen index values, oxidation-reduction potential, temperature and surface water rate of Uzynbulak brook were determined.
Seminar–round table organizers noted high level of papers preparation, presented by the team of young scientists of the National Nuclear Center of the Republic of Kazakhstan.
