BACKGROUND
The Laboratory has been involved in the process of minimizing the consequences of the Chernobyl disaster since 1986. Significant experience has been accumulated since then related to operational actions for evaluating the radiation situation, establishing emergency zones, radiation control and environmental monitoring. Starting from 1993, the principal activities of the Lab are associated mostly with scientific support of the National Programs on Overcoming the Consequences of the Chernobyl Accident.
In the context of the Union State the Lab took an active role in implementing the Programs of Joint Efforts for Overcoming the Chernobyl Accident Consequences providing its expertise and developing a unified database and the essential elements of radiation control and monitoring system for contaminated areas of Belarus and Russian Federation. As well as that, a number of pilot projects were implemented aimed at obtaining agricultural products in compliance with the specified standard limits.
In 2012, on request of the Ministry for Emergency Situations of the Republic of Belarus the Laboratory developed the "Requirements for the structure and content of the external emergency plan of the Belarusian NPP". Development of these requirements was part of the assignment "Create a new decision-support system for emergency response to radiation emergencies associated with nuclear facilities in the Republic of Belarus" under the State Program "Scientific support of development of nuclear power in the Republic of Belarus for 2009-2010 and for the period up to 2020".
The Lab specialists were also involved in implementation of the National Investment Program "Construction of a nuclear power plant, including project design estimates and exploration works" in terms of "Substantiation of the need to invest in the construction of a nuclear power plant in the Republic of Belarus" (Milestone 4: Environmental Impact Assessment).
In 2013 our Lab was busy with radioecological assessments of the site’s actual background contamination levels and development of a radiation monitoring program to monitor the agro-ecosystems in the area of the first Belarusian NPP site.
BASIC OBJECTIVES OF RESEARCH
• Development of the models and software products for predicting radionuclide concentrations in the environment and forecasting radiation doses;
• Development of targeted protective measures to reduce exposure to the population;
• Expert and methodological scientific support of stakeholders involved in the emergency response system in the event of a release of radioactive substances at nuclear facilities;
• Radioecology-related research and development of radiation monitoring systems.
MAJOR RESEARCH DEVELOPMENTS over the last 5 years
2012
• Requirements for the structure and content of the external emergency plan of the Belarusian NPP;
• Forecast of radioactive contamination of agricultural lands and products with 131I, 137Cs and 90Sr caused by the Ostrovets NPP operation.
2011
• Recommendations on calculation of committed effective doses for emergency response workers operating in the area of radioactive contamination;
• Risk Assessment System: assessing the risks of 137Cs and 90Sr concentrations in agricultural products exceeding the regulation values.
2010
• Electronic Register of Belarusian Lands excluded from economic use as a result of radioactive contamination (Technical Cooperation Project RER/3/004 "Radiological Support for the Rehabilitation of the Areas Affected by the Chernobyl Nuclear Power Plant Accident");
• Automatic Forecasting Software to forecast 137Cs and 90Sr concentrations in agricultural crops based on arbitrary values of soil parameters.
2009
• Forecast of external and internal agro-ecosystem radiation exposure caused by routine and emergency releases at projected Belarusian NPP;
• The model for prediction of radioactive contamination of the atmospheric surface layer, surface soils, agricultural products, and radiation doses;
• GIS Database on Mineral Resources: search, analyses, and visualization of information on the current state of the mineral resources available in contaminated areas;
• Multidimensional regression model and forecasting software to predict 90Sr behavior in the soil – plant system (designed for agronomists of agricultural organizations in the contaminated areas)
2008
• Mathematical model to describe the processes in soils, and forecasting software to predict 137Cs concentrations in agricultural products;
• Spatiotemporal database of radionuclide concentration values in foodstuffs;
• Calculation Software: Composition of dairy and beef cattle rations for differentiated use of feed with various levels of radioactive contamination бесплатно шаблоны dle 10 на сайте newtemplates.ru и скачать фильмы у нас на сайте есть скачать игры бесплатно бесплатно
