Project summary

Problem.

Lake Issyk-Kul is one of a number of reservation sites, with worldwide significance,e defined by the Ramsar Convention in 1975. In Kyrgyzstan, the Issyk-Kul region was given the status of a Biosphere Territory. This requires the continuous environmental monitoring of the Biosphere’s state. At present UNESCO considers the question of the confirmation of the international status of Biosphere Territory to Lake Issyk-Kul that shows the role of this unique natural site in the global geo-biosphere system. In this connection, the problems of environmental protection of the adjacent territories become especially urgent. These territories are located in ecosystems with a high content of natural radionuclides. The environmental problems of the Issyk-Kul zone are additionally heightened by the fact that, for a long time, in this region uranium raw material has been obtained for the atomic industry of the USSR. Tailings and dumps being subject to the influence of natural factors – wind, rains, mudflows, and landslides – are weathered and washed out. This results in the radionuclide contamination of soils, underground waters, flora and fauna on the adjacent territories of the Issyk-Kul basin.

For the development of protective measures for the population against environmentally unfavourable factors, in particular, it is necessary to really evaluate the radiation load on the population. This raises the problems of organization of the control for radon, its "daughter" products of decay, transuranic elements and other natural radionuclides released into the soils air, underground and drinking waters.

In this connection, ensuring the safety of the Biosphere territory of Lake Issyk-Kul requires the creation of the complex automated system of the impact environmental monitoring allowing the accumulation of databases on the state of the natural environment surrounding humans (background and impact monitoring of the geochemical and anthropogenic dispersion on the elemental and radionuclide levels) within the inhabited zone of Lake Issyk-Kul.

Solution of these tasks requires the attraction and development of special techniques and technologies, controlling both the release of harmful substances (including radioactive ones) and their distribution in soils, water, the soil-vegetable layer and air. The above listed matters may be solved within the frame of a radiation-biogeoecological conception with the use of well known approaches, recommendations of the International Commission on Radiological Protection (ICRP), as well as the approaches developed by the European Union.

The goals of the project are as follows:

Creation of a complex automated, technically equipped, system for the background and impact ecological monitoring of the natural environment's state at the biosphere territory of the inhabiting zone of Lake Issyk-Kul and creation of a database on the sources and objects of the natural and technogenic radiation effect.

The objectives of the project are as follows:

1. Creation of a technically equipped analytical base using high-sensitive (stationary and mobile) detectors and detecting complexes with the required software for radioecological monitoring.


2. Development of technologies and methods of obtaining radiometric and dosimetric information, which meet the requirements of "expressness", low cost, trustworthiness, ease of operation and simplicity.
3. Metrological attestation of the created equipment and methods.
4. Creation of the radon measuring net based on track detectors.
5. Development of methodic and programming-mathematical software for the processing and analysis of the registered information and its submission in electronic format.
6. Holding the impact radiogeoecological monitoring of the inhabiting zone of Lake Issyk-Kul with the use of a technically equipped analytical information base.
7. Collecting and managing the databases, data processing, creation of the archive databases, presentation of the data in table and visual screen formats.
8. Zoning of the inhabiting zone of Lake Issyk-Kul by radioecological and geoecological factors.
9. Creation of a Web-site on the Internet, containing the updated radiological and geoecological information on the environment state in the basin of Lake Issyk-Kul.

Participants of the project are highly qualified experts in the field of radiation physics, radioecology, spectroscopy and spectrometry; they have sufficient experience in the creation of materials and equipment for the registration and study of ionizing irradiation by different methods, experience in the field of radioecological control of the environment and of nuclear wastes. They participated in the development of the equipment for the registration of super-small doses of irradiation; took part in the radioecological examination of the World Ocean's waters, territories of Chernobyl AES and East-Ural radioactive track. They have all the necessary methods and equipment for carrying out the research on the project and methods of interpretation of the experimental results.

Expected Results and their Application.

The project refers to the category "Applied researches".

As a result of the project implementation, at the inhabited zone of the Biosphere territory of the Issyk-Kul oblast, Kyrgyz Republic, there will be created a technically equipped laboratory-analytical base, which will allow performing the background and impact radiogeoecological express-control of the state of the examined territory. On the basis of the created technically equipped measuring net, performed measures with the use of the developed methodical and programming-mathematical software there will be organized databases on the results of the background and impact radiogeoecological control. The results will be distributed among the interested authorities of Kyrgyzstan and the international organizations working on this problem within the ISTC-projects.
