XII REGIONAL SCIENTIFIC CONFERENCE "TECHNOGENIC SYSTEMS AND ECOLOGICAL RISK"

BOT: 10.7868/80869803115040104

Since 2004, the Obninsk Institute of Atomic Energy (Obninsk) annually hosts Regional Scientific Conferences “Technogenic Systems and Environmental Risk”. The next 12th conference took place on April 23-24, 2015. The Obninsk Institute of Nuclear Energy is currently the largest branch of the National Research Nuclear University "MEPhI" and traditionally acts as a base university for the Rosatom State Corporation, providing specialized training for young specialists for nuclear energy and related fields, including radiation ecology and biology, radionuclide medicine, chemistry, physics and mechanics of materials. Therefore, the main participants of the conference are young scientists, teachers and senior students from the city of Obninsk, large scientific centers and universities in the European part of Russia, as well as neighboring countries (Ukraine, the Republic of Belarus, the Republic of Kazakhstan).

In the welcoming words addressed to the conference participants by the director of the Institute of Nuclear Energy of National Research Nuclear University MEPhI N.G. Airapetova, chairman of the program committee, academician of the Russian Academy of Sciences R.M. Aleksakhin, Chairman of the Kaluga regional branch of the Russian Academy of Natural Sciences, Professor A.I. Trofimov, representatives of the conference organizing committee, called on young people to actively participate in solving important scientific problems that are currently facing in the field of nuclear energy development, assessing and preventing the adverse consequences of man-made human activity, and minimizing man-made risks, including radiation accidents.

The topic of the plenary session, from which the conference began, was devoted to issues closely related to the fundamental and practical aspects of radioecology and radiation safety. The current state of the state environmental monitoring system was highlighted in his report by the director of the Institute of Environmental Monitoring Problems of the NPO Typhoon V.G. Bulgakov, who spoke about the work to create an integrated system of comprehensive observations, the modernization of the Roshydromet observation network launched in recent years, the radiation monitoring system and the radiation situation in Russia, including the activities of Roshydromet in the period after the Fukushima accident. The problem report was presented by I.I. Kryshev (NPO Typhoon), who touched upon the historical aspects of the formation of methodological principles of radiation safety and the role of the individual in the history of science, spoke about modern views on radiation protection of the environment, the latest international documents and developments of Russian scientists, presented unique data on the practical application of radioecological models to assess the radiation impact on biota in areas where nuclear energy facilities are located. Plenary speeches determined the scientific

nal, production, organizational guidelines for assessing and forecasting the state of the environment, regulating and minimizing technogenic impacts and risks.

In 2015, the conference brought together about 100 participants, 80 applications for presentations were received, and 40 reports were presented. The conference topics covered a wide range of issues in the field of ensuring the environmental safety of the biosphere, combined into six sections: Nuclear and thermal energy, modern environmental technologies; Problems of waste disposal, radioactive waste storage facilities; Technogenic and environmental risks; Biotesting and bioindication of environmental objects; Environmental and pharmaceutical chemistry; Ecological aspects of the effects of non-ionizing and ionizing radiation. The breakout sessions were mainly attended by young participants; their work, as a rule, reflects the research directions that are currently being implemented in leading scientific teams in Russia and neighboring countries. Although the stated topic of the conference is very broad and includes many aspects related to the study of technogenic factors in the human environment, a significant part of the materials presented at these conferences traditionally concerns issues of radiation ecology and radiobiology.

The problems of monitoring research, voiced at the opening of the conference, were continued by the report of N.V. Ageeva (NPO "Typhoon"), which presented data on the dynamics of the content of radioactive strontium in surface waters of Russia using the example of rivers flowing through the background and contaminated territory (EURT), and studied the influence of the water regime of the territory on the removal of radionuclide into surface waters.

One of the main problems of nuclear energy is the safe management of radioactive waste. Currently, many near-surface storage facilities created 50-60 years ago do not fully comply with radiation safety requirements. The results obtained in long-term research carried out by employees of the Departments of Ecology and Biology of the IATE NRNU MEPhI in the zone of influence of the regional radioactive waste storage facility in Obninsk were discussed. It has been shown that the specific active

The content of C8 in soils varies widely from 3 to 22 Bq/kg; an excess of the background value was observed at two sampling points; the bulk of the radionuclide (67%) is in a tightly bound form. When biotesting water samples from control wells of the radioactive waste storage facility containing increased concentrations of 90 g, changes in biochemical parameters (activity of superoxide dismutase, catalase, peroxidase and shikimate dehydrogenase) were revealed in all test objects (cress, planaria, daphnia).

XII REGIONAL SCIENTIFIC CONFERENCE

As part of the joint work of VNIIRAE, FMBC named after. A.I. Burnazyan and IATE NRNU MEPhI studied the condition of the territory of the industrial site and the sanitary protection zone of the Far Eastern Center for Radioactive Waste Management; When assessing the phytotoxicity of soils, it was shown that the morphophysiological parameters of the test object (cress) had a direct correlation with the level of soil contamination with technogenic radionuclides.

A number of papers present assessments of the environmental impact of nuclear fuel cycle facilities or radioactive contamination resulting from radiation accidents. A comparative analysis of the radiation impact of the Krasnoyarsk Mining and Chemical Combine and the Siberian Chemical Combine on reference species of aquatic and terrestrial fauna was carried out by K.V. Lunevoy (NPO "Typhoon"). The consequences of chronic irradiation of biota have been studied by VNIIRAE specialists for many years using the example of pine populations in the Bryansk region, contaminated as a result of the Chernobyl accident. Young researchers presented the latest data on the levels of cytogenetic effects and reproductive ability in Scots pine populations growing in contaminated areas, and showed that against the background of an increase in the frequency of mutational events in the G6PD isoenzyme loci with an increase in the absorbed dose, the enzymatic activity in the seeds does not change, that suggests leveling out the effects of irradiation at higher levels of biological organization.

Reducing the impact of nuclear fuel cycle facilities on humans and the natural environment is an important task of radiation protection of the population and the environment. To solve one of the key issues - reducing radioactive iodine emissions at nuclear power plants - M.A. Alekseeva (Obninsk Center for Science and Technology) proposed using microwave processing of plant materials to obtain hydrocarbon adsorbents. Testing of samples of peat-based sorbents showed that the purification efficiency for radioactive iodine increases from 89 to 95.8% when the sorbent is impregnated with a complex compound based on silver nitrate and potassium iodide. Another aspect of reducing the impact on the environment - optimization of methods for developing standards for permissible discharges - was presented by the environmental protection department of the Smolensk NPP.

Scientific research in the field of radiobiology concerned the study of the characteristics of densely ionizing radiation, the stimulating effects of y-radiation, as well as the radiobiology of non-ionizing radiation.

At the Medical Radiological Research Center (Obninsk), a study was carried out of the patterns of late formation of colonies by irradiated yeast cells depending on the quality of radiation; It has been shown that the biological effectiveness of densely ionizing radiation (a-particles) is 4 times higher than that of rarely ionizing y-radiation.

As part of the development of radiation technologies for agriculture, VNIIRAE is conducting work to study the biochemical mechanisms of the formation of stimulating effects during pre-sowing irradiation of agricultural crops. Data were presented on the dependence of the activity of the enzymes pyruvate kinase and peroxidase in barley seedlings on the dose of acute γ-irradiation of seeds. The inhibitory effect of high doses of radiation on growth performance and the concentration of chlorophyll A was shown in a similar series of experiments studying biochemical

the chemical and morphological characteristics of barley seedlings after y-irradiation of seeds in doses of 0.1-100 Gy, implemented at the Department of Biology of the Institute of Nuclear Energy of National Research Nuclear University MEPhI.

Research into the effect of electromagnetic fields on biological objects is also being developed at the Institute of Atomic Energy of the National Research Nuclear University MEPhI. The results of work were presented indicating the influence of low-intensity EMR in the mobile communication frequency range on biochemical processes and reproductive functions in daphnia. An unfavorable effect of radiofrequency EMF on the state of the reproductive system of male rats was detected during subacute exposure in the frequency range of the DECT standard (Research Institute of Occupational Medicine, Moscow). The results of studying the combined effects of ionizing (X-ray) and non-ionizing (infrared) radiation on mouse offspring using the tests “radiosensitivity” and “adaptive response in bone marrow, lymphoid organs and whole blood” were presented by A.R. Dyukina (ITEB, Pushchino).

Udalova A.A. - 2011

The 1st International Scientific Conference “Technogenic Systems and Environmental Risk” was held at NRNU MEPhI (Obninsk). The conference is aimed at considering current scientific problems related to the study of technogenic factors in the human environment, assessing the effect of these factors on humans and natural systems, and ensuring the environmental safety of the biosphere.

The conference preserves the 13-year tradition of holding a regional youth conference with the same name, the geography of which has long gone beyond the borders of the region. The international status of the event is confirmed by the regular participation of young specialists from Belarus, Kazakhstan, Ukraine, as well as a significant increase in the number of foreign students at NRNU MEPhI - potential conference participants. In this regard, in the Year of Ecology, it was decided to assign this event the status of an international conference.

The event attracted a record number of participants. The conference organizing committee received 180 applications for participation from research and educational institutions in Obninsk, Kaluga, Moscow and the Moscow region (Dimitrovgrad, Pushchino), Bryansk, Irkutsk, Yoshkar-Ola, Kazan, Kirov, Kursk, Murmansk, Nizhny Novgorod, Novocherkassk, Orel, Rostov-on-Don, Saratov, Simferopol, Tomsk, Cherepovets, as well as Minsk, Mogilev, Gomel (Belarus), Kurchatov (Kazakhstan), Bishkek (Kyrgyzstan), Kyiv (Ukraine). The conference was attended by 170 people who presented 80 in-person reports. A significant number of students of the Technical College and IATE NRNU MEPhI attended the plenary and sectional sessions as listeners. The share of foreign conference participants was 16%. The conference helps to increase the level of knowledge of young scientists and teachers, exchange experience in conducting scientific research and teaching activities, and establish connections between organizations, regions and countries.

At the grand opening of the conference, Deputy Director for Research and Innovation S.A. addressed the participants with a welcoming speech. Kosarev, Academician of the Russian Academy of Sciences, Doctor of Biological Sciences R.M. Aleksakhin, head department ecology IATE NRNU MEPhI, Doctor of Biological Sciences A.A. Udalova.

The topic of the plenary session, which began the conference, was dedicated to the Year of Ecology and covered both environmental safety issues in the field of atomic energy use and biomedical problems of non-ionizing radiation. Plenary reports were presented by Academician of the Russian Academy of Sciences, scientific director of VNIIRAE, chief ecologist of the “Breakthrough” project, Doctor of Biological Sciences R.M. Aleksakhin (Radioecology: problems of nuclear energy when using fast reactors and closing the nuclear fuel cycle) and Deputy Director for the organization of scientific and experimental work of the MRRC named after. A.F. Tsyba, Doctor of Medical Sciences L.P. Zhavoronkov (Low energy EMF is an environmentally significant factor. Reality and prospects). Both reports aroused great interest from the audience and lively discussion.

The conference traditionally featured six sections:

• Section 1 “Nuclear and thermal energy, modern environmental technologies”;
• Section 2 “Problems of waste disposal, radioactive waste storage facilities”;
• Section 3 “Technogenic and environmental risks”;
• Section 4 “Biotesting and bioindication of environmental objects”;
• Section 5 “Environmental and pharmaceutical chemistry”;
• Section 6 “Ecological aspects of the effects of non-ionizing and ionizing radiation.”

For the first time, within the framework of the scientific conference of the IATE NRNU MEPhI, a School Environmental Section was held, which turned out to be very fruitful and interesting. Pupils of grades 4-11 from schools in the Kaluga region presented 33 scientific reports.

Another distinctive feature of this year’s conference was the organization of the master class “Biotesting on Planarians”, which was conducted by Kh.P. Tiras (candidate of biological sciences, vice-rector for scientific and innovative work of the Pushchino State Natural Science Institute (Pushchino), Pushchino).
