Project summary

The Project aims at:
Creation of radio-ecological map schemes for regions of the South Caucasus exposed to Chernobyl pollution.
Creation of grounded prognosis of radiation pollution of territories of the South Caucasus in case of radiation accidents, at different scenarios of accident development.
Estimation of ecological and economical damage at different scenarios of accident development and prognosis for rehabilitation of the ecosystem of the South Caucasus regions.
Elaboration of recommendations for the governmental organizations of Georgia and Armenia on managing accident planning with the aim of providing security for the population in case of radiation accident.
Elaboration and creation of new coordination-sensitive detectors of radionuclides on the basis of porous materials, with 100% efficiency of registration.
Problem topicality: For the past ten years no systematic inspection has been conducted on the territories of the South Caucasus exposed to radiation pollution, caused by the Chernobyl accident. The lack of objective data on the radiation condition creates an unfavorable background for the social-economical development of the South Caucasian regions and assists in heightening social tension. Therefore, it is very important to possess a real, objective picture of the radiation situation.
After the Chernobyl accident, considerable organization-technical work was performed on increasing the safety of NPP equipment all over the world and, also, on all the energy blocks of Soviet production. Nevertheless, the governmental interests of the South Caucasus countries dictate the need to account for the possibility of an accident at an NPP. Therefore, the creation of scientifically grounded prognosis of possible radiation pollution of the South Caucasus territories in case of accident at an NPP and its spatiotemporal dynamics represents a vital problem, which has practical significance.

The novelty of solving problems:
Experimental measuring and mathematical modeling based thereupon, represent one of the most powerful methods of studying such complicated phenomena as radionuclide explosion during a nuclear accident and the atmospheric transference of these radionuclides over great distances. At present, there are a great number of program packages for calculating special atmospheric events (weather forecasts), and for modeling atmospheric transference of aerosol patterns. The difficulty of using the available program packages is conditioned by specific conditions of the South Caucasus, which is characterized by a vast variety of relief, landscape and climate factors, which greatly influence the speed and ways of radionuclide transference. All this stipulates the need for the creation of an essentially new model, considering the conditions of the South Caucasus. It is also obvious that the prognosis should be based on the real condition of the pollution of these territories. For the creation of map schemes of radiation pollution territories exposed to Chernobyl pollution, comprehensive methods of ground and air radiometry and radio-spectrometry will be used. In addition, the structure and concentration of radioactive micro-patterns in the soil are to be investigated. To perform this task a new radionuclide detector will be elaborated and created on basis of porous materials with high multi-particle efficiency (close to 100%) and high space resolution.

Expected results:
In the process of project implementation, following results will be achieved:
Composition of radioactive map schemes of South Caucasus regions exposed to Chernobyl pollution.
Elaboration of a package of programs modeling the dynamics of the development of possible radiation accidents and a scale-time picture of atmospheric transference of radioactive aerosols, considering nature-climate conditions of the South Caucasus.
Composition of map schemes of prognosis of radiation pollution of South Caucasus regions in case of radiation accident at different scenarios of accident development and for different weather conditions.
Composition of map schemes of economical and ecological damage of South Caucasus regions at different scenarios of development of possible radiation accidents and prognosis for rehabilitation of the ecosystem.
Elaboration of recommendations for governmental organizations of Georgia and Armenia on organizing emergency planning in case of radiation accident development with the purpose of providing security for the population.
Development and design of a new coordination-sensitive detector of radionuclides with 100% multi-particle efficiency, on the basis of porous materials.
The results and recommendations will be passed to relevant governmental organizations of the South Caucasus regions (ministries and departments) as practical recommendations for analysis and prognosis of ecological damage and estimation of deadlines of natural rehabilitation of polluted territories.
It is obvious that these results can be applied to other regions with similar nature-climate conditions.
Project implementation represents an alternative direction for defense scientists and it will allow the reestablishment of relationships between the scientific centers of Armenia and Georgia, for their cooperation in radiation ecology. It will also help the scientists of these countries to cooperate with scientists of the West in solving vital scientific and applied problems, facing mankind.
The project fully corresponds to the goals and tasks of the ISTC.
The basis for fulfilling the project is collected methodological, experimental and inpidual potential, and the experience of specialist participants of the project, working in nuclear physics: gamma spectrometry, radiation physics and radio-ecology.
Foreign scientists, working in applied physics and the modeling of catastrophic phenomena including modeling of radiation pollution in case of accident at an NPP, are to participate in the project elaboration as collaborators.
