Project summary

Existing radioecological problems of Yssyk-Kul region of Kyrgyz Republic are conditioned by the presence of former sites of uranium production and zones of high natural radioactivity.

Currently, uranium production is stopped, but remaining dumps of uranium pits, slurry ponds and tailing ponds with great content of radioactive substances under the impact of natural factors such as wind, rain, mud flows, earth creep are weathered and eroded. This leads to the fact that radioactive substances go beyond extraction and processing sites, causing subsequent radionuclide contamination of soil, underground waters, flora and fauna on the territories near Yssyk-Kul basin.

Besides, practically the whole territory of Yssyk-Kul region and especially, territories near mountain lake Yssyk-Kul are located in ecologic radiochemical zones with high content of natural radionuclides such as uranium, radium, thorium, radon. As the result of it, the level of natural radiation background in Yssyk-Kul region exceeds the average one in Kyrgyz Republic.

However, currently, in Kyrgyz Republic, there is no system of radiation monitoring of the regions with conserved uranium pits and other territories with high level of radiation, there are no information structures of data acquisition and analysis of necessary data about these sites. In these conditions of importance is the problem to develop technical means and technologies for future single Kyrgyz national system of radiation monitoring of territories and water expanses.

The goal of the Project is to build detection systems and technologies to perform radiation monitoring in the region of conserved uranium pits and selected territories of Yssyk-Kul region of Kyrgyz Republic. One more goal is to equip Training and Operative Center of radiation safety at physical and technical faculty of Yssyk-Kul State University comprising unified Kyrgyz national system of radiation monitoring of territories and expanses of water.

The main components of this system are up-to-date high sensitive systems of detection, technologies of operative monitoring, acquisition and presentation of obtained experimental data meeting the requirements to provide reliability, operability and clearness of obtained radiometric and dosimetric information.

Detection systems under development will include dosimetric complexes on the basis of thermoluminecsent and scintillation detectors of gamma radiation, multi-purpose field gamma spectrometric modules, sampling and measuring module for radon monitoring. These technologies will include methodical provision and software to conduct measurements, acquisition, analysis and presentation of monitoring data in the form of maps.

Obtained information, including assessments of radiation risk for separate groups of population will permit for corresponding state structures to have more reliable prediction of natural-ecological and hence economical situation in the regions.

Solution of problems related to the development of a single Kyrgyz national system of radiation monitoring of the territories and water reservoirs ca be solved by joint efforts of Kyrgyz republic and Russian Federation using world, Russian and Kyrgyz experience of investigations and developments.

Institute of Physics of National Academy of Sciences and Yssyk-Kul State University of Tynystanov of Kyrgyz Republic performs development and investigation of properties of high sensitive thermoluminescent detectors and dosimetric systems on base of fluoride thermoluminophors for dosimetry of X-ray and gamma radiation and have practical experience in monitoring investigations.

Ural State Technical University has many-year experience of development of thermoluminescent oxide detectors and dosimetric systems on the basis of oxide thermoluminophors. As well as developments of semiconductor spectrometers of X-ray and gamma ranges with high energetic resolution on the basis of Cd-Te detectors and special units of electronics not requiring cooling by liquid nitrogen.

Zababakhin RFNC-VNIITF has many-year experience and developments in the field of building technical means, theoretical and experimental techniques to control, model and predict radiation situation to conduct nuclear tests and radioecological investigations of the territories contaminated by radionuclides as the result of radiation accident.

As the result of realization of the project, approaches and technology of radiation monitoring, risk assessment will be developed and experimental samples will be created, including:

- thermoluminescent detectors of high sensitivity on fluoride and oxide basis and thermoluminescent dosimetric complexes;
- semi-conductive spectrometer of X-ray and gamma radiation with high energetic resolution not requiring cooling by liquid nitrogen;
- scintillation gamma spectrometric module for gamma survey and gamma spectrometry of samples on site;
- portable sampling and measuring module for radon monitoring.

Using created samples of detecting devices and technologies, including high sensitive thermoluminescent dosimeters, gamma survey, gamma spectrometry of samples and radon measurements, radiation monitoring will be made in the region of uranium pits and selected territoryies of Yssyk-Kul region.

As the results of monitoring, topograms of exposure dose of gamma radiation will be built to investigate objects and territories of Yssyk-Kul region, determination will be made for the characteristics of the most dangerous objects and assessment will made for radiation risk for separate groups of population of Yssyk-Kul region.

Developed samples and technologies will be used for equipment of future Training and Operative Center of radiation safety (YSU, Karakol) which a part of future single Kyrgyz national system of radiation monitoring of territories and water expanses.

Realization of the project will have important meaning in the terms of performance of ISTC goals:

- the project is facilitating solution of general problem of CIS states – development of new means of detection of ionizing radiation for monitoring of radiation dangerous objects and territories;
- the project is facilitating integration and use of scientific and engineer conversion potential of CIS states in realization of developments of scientific and applied character, the results of which will be used only in peaceful purposes;
- the project provides for acceleration and introduction of new developments in the field of radiation monitoring of the territories and aquatoria for future unified Kyrgyz national system of radiation monitoring.

Activity on the project is performed in the frames of developments and investigations formulated in the form of 8 Tasks.

Task 1 on the development of approaches of monitoring and selection of means and technologies is related to initial and ideological part of developments. Solution of Task 6 (monitoring investigations), Task 7 (radiation risk assessment) and Task 8 (technical equipment of Training and Operative Center on the problems of radiation safety) is considered as the most important practical result of work. Performance of these Tasks having complex character is planned with participation of all institutions-participants.

The Task of building thermoluminescent systems (Task 2) is solved together with the specialists of Institute of Physics of Kyrgyz Republic and Ural State technical university.

Experimental sample of field (not cooled by liquid nitrogen) semi-conducting spectrometer of gamma and X-ray range and the technology of its application (Task 3) are created on the basis of Ural State Technical University.

Scientific and practical experience of RFNC-VNIITF and Ural State Technical University provides to use radon-monitoring samples while developing systems and technologies of gamma survey, gamma spectrometry.

Reports presented on the results of performed work include:

- 3 scientific reports (Tasks 1, 6, 7);
- protocols of tests and complexes of operation and methodical documents (Tasks 2-5);
- program, protocol and act of equipment of Training and Operative Center (Task 8).

Collaboration with foreign institutions may include: information exchange in the course of project performance, joint symposia and working workshops, joint publications of selected results.

Technical approaches and methodologies used in the project are based on scientific and technical achievements of world level in the field of nuclear machine building, radiation and radioecological investigations. Achievements of final goal of the project and obtaining important practical results are performed with the principle of necessary sufficiency and criterion «cost-effectiveness».

The development of specific systems of detection and monitoring technologies is performed on the basis of original developments, scientific and practical experience of institutes-participants of the project.
