AbstractAbstract
[en] The system of the radiation control and monitoring of the natural environment which are carried out by Department of hydrometeorology of the Ministry of natural resources and preservation of the environment, includes supervision over pollution of surface waters, bottom sediments, atmospheric air and soil by radionuclides. Supervision is realized at 57 servers, where exposure gamma rate (EDR) is daily measured. The radioactive fallout's from atmospheric air are controlled with use of horizontal plane tables on 30 servers located on all the territory of the Republic. In five towns of Belarus (Minsk, Mogilev, Gomel, Brest, Pinsk) a content of radioactive aerosols in the air is daily measured with the use of the filter-ventilating station In the first period of the catastrophe the levels of exposure gamma rate in Bragin have made - 46000 micro R/h (distance up to Chernobyl NPP - 50 kms), in Chechersk - 10000 micro R/h (distance up to Chernobyl NPP - 180 kms) In June 2002 the maximum single levels were fixed in Bragin - 105 micro R/h and in July in Chechersk - 32 micro R/h. On the rest of the territory the exposure doze rate of gamma - radiation does not exceed the levels of natural gamma - hum noise (up to 20 micro R/h). In regional towns the average annual levels have made from 10 up to 15 micro R/h. The statistical data processing of measurements of exposure gamma rate in 10 most typical the settlements shows, that two groups of the settlements can be selected: with low values EDR up to 20 micro R/h: Lel'chitsy, Mozyr', Slutsk, Mogilev, Pinsk and with values EDR more than 20 micro R/h: Slavgorod, Khojniki, Bragin, Chechersk and Narovlya. The analysis of outcomes of observations behind a state of an atmospheric air has shown, that in 2002 it is not revealed short-lived radionuclides, is not marked of essential changes in behavior cesium-137 and strontium -90 in an atmosphere in comparison with the previous years in post-accident period. Investigation, which are carried out for period 1990-2002 have shown, that the seasonal increases of a radioactivity of an atmospheric air happen. For want of analysis of tests of aerosols and fall outs it is possible to mark, that the concentration radionuclides caesium and strontium in low-level of an atmosphere are largely determined by a content of a dust in an air, i.e. processes of secondary wind rise (authors)

AbstractAbstract
[en] The data on radioecology of the rivers of Belarus, which catchment area is completely or partly situated in Russia and Ukraine (Sozh, Iput, Besed, the Braginka) are given. The radioactive contaminations of lakes are represented. Transboundary transfer of radionuclides by water way (Russia - Belarus - Ukraine) are estimated. Total activities of Cs-137 on the catchment of rivers which are large tributaries of the Dnieper river and run off of this radionuclide through the transboundary control points for period 1987-2002 are calculated. It was shown, that nowadays main transboundary transfer of radionuclides by water way is realized only by Pripyat river and its tributaries because its catchment completely or partly situated in exclusion zone. The article demonstrates that now natural rehabilitation in big and medium rivers of Dnieper basin has been and levels of radionuclides content in surface waters have considerably decreased in comparison with initial levels. At the same time closed water bodies (lakes, ponds, water reservoirs) have saved up and continue to save up radionuclides due to erosion and sedimentation. Some of such water bodies have approached to level of intervention and have surpassed it on levels of radioactive contamination of fish. Secondary affects of radioactive contamination of water bodies of Dnieper basin are estimated. Other potential sources of radioactive contamination of the Dnieper basin are considered. One of the scripts of radioactive pollution of its catchment as a result of potential accident on the Ignalina nuclear power plant is submitted. (Authors)

AbstractAbstract
[en] As a result of Chernobyl NPP accident, the greatest quantity of radionuclides has fallen on the territory of Belarus, therefore 23% of the territory have been contaminated with Cs 137 with a level exceeding 37 kBq/m2 on the total area of 46.45 thousand km2 that has led to the exclusion from an agricultural rotation 2,64 thousand km2 of farmland. Now, external gamma-radiation on the territory of Belarus is formed due to 'Chernobyl' and 'global' (caused by tests of the nuclear weapon) radioactive losses. A contribution is also done by natural radioactivity. To-date, due to natural radionuclides decay a radiation conditions in zones of Chernobyl contamination has been stabilized and main dose formation radionuclide is Cs 137. In conformity with clause 4 of the Law 'On legal regime of territories, exposed to radioactive contamination after the Chernobyl nuclear power plant accident' the territory of the Republic of Belarus is divided into zones depending on radioactive contamination of soil by radionuclides and sizes of a mean-annual effective dose. The estimation of a dose of external irradiation demands establishment of interrelation between the level of soil contamination with radionuclides and created by them exposure dose power (EDP). As a quantitative size of this link, a normalized on density of contamination of soil Cs 137 EDP at 1 m height is most used which is formed by all radionuclides and is called the transition coefficient 'density of contamination of soil Cs 137 - EDP'. In the given work, empirical values of factor of transition on items of supervision of a network of the radiation monitoring, registered in National System of Environment Monitoring (NSEM) Republic of Belarus have been determined. The carried out data analysis for 1993-2003 showed, that: Value of transition factor within 10 years have changed from 0,054 μ R/h/kBq·m2 to 0,041 μ R/h/kBq·m2 (with 2,0 μ R/h/Ci·km2 to 1,5 μ R/h/Ci·km2). Decrease of EDP from 'Chernobyl' radioactive precipitation at a late stage after the Chernobyl accident is defined by radioactive disintegration of Cs 137, resulting 80% EDP decrease for 1993-2003. To assess an external irradiation dose of inhabitants of settlements which are in zone of radioactive contamination, it is possible to use a value of the transition factor, obtained by results of measurements on observation sites of a network of radiating monitoring NSEM, without making EDP measurement in every radioactive contamination zone settlements.

AbstractAbstract
[en] After Chernobyl catastrophes the system of radiation monitoring of the environment in Belarus has ensured the collection and analysis of information about radioactive contamination of an atmospheric air, surface waters and territories. These results of radiation monitoring are used for an estimation of a radiation condition of a environment and prognosis it of restoring. The analysis of results of monitoring shows, that in the first period after catastrophe the maximum levels of a exposure gamma-ray dose in cities were fixed in Bragin (April 30, 1986). The numerical prognosis shows, that the restoring of this magnitude lakes before catastrophe is possible to expect approximately in 65 years. The map of contamination of Belarus by Cs-137 was constructed about use Geo Information System based of results of monitoring, which are introduced in an automated data bank. Due to use GIS the prognosis of restoring of the contaminated territories, contaminated by Cs-137 to 2016 and 2046 was obtained. The analysis of dynamics of squares of contamination more than 37 kBq/sq.m for period 1986 - 2046 shows: The square of initial contamination (1986) by Cs-137 more than 37 kBq/sq.m was equaled 23,7 %; In 30 years (2016) squares of contamination will make approximately 16 %, i.e. will decrease in 1,5 on a comparison 1986; In 60 years (2046) squares of contamination will make approximately 10 %, i.e. will decrease in 2,4 on a comparison 1986. The prognosis of space distribution of activity Am-241 in Belarus shows, that the high levels of contamination will be in 30-km to a zone Chernobyl NPP and on around territories, where the population lives. Maximum volumes the activity of Am-241 will achieve to 2060 and will exceed activity of Pu-238,239,240 approximately in 2 times

AbstractAbstract
[en] Inventory and systematization of the data on radioactive-chemical contamination of rivers are made. Systematization of the data on chemical and radiation contamination component of rivers was made with using the index of integrated radiation-chemical surface waters contamination (IRCCI=WCI+RCI). Chemical contamination of surface water has been estimated using water contamination index (WCI). It constitutes an integrated magnitude considering ratios of six more significant pollutants to their maximum concentration limits. In dependence on WCI surface water can be attributed to one of seven classes: from 'clean' (with WCI≤1) to 'extremely dirty' (with WCI>10). At present for estimation of radioactive contamination of surface water only comparison with Republican permissible levels are used. But it is not enough for complex estimation of water quality because it does not enable to estimate the extent of radionuclide exceeding over their permissible levels. Therefore for estimation of radioactive pollution level, water radioactive contamination index (RCI) was applied. It is a sum of ratios of main radionuclide concentrations to their permissible levels. Application of RCI enabled to compare radioactive contamination before and after the Chernobyl accident. Application of the index of integrated radiation-chemical surface water contamination enabled to obtain the most complete and impartial estimate of surface water quality of some rivers. Retrospective estimation of the water quality shows that in 1990 surface waters of some rivers should be considered as belonging to more contaminated category of quality if radiation component would have been considered.

AbstractAbstract
[en] As a result of the Chernobyl accident water bodies on the territory of Bryansk-Gomel-Mogilev spot have been contaminated with radionuclides. Now the concentration of long living radionuclides in surface waters is determined by secondary processes: radionuclides wash off from the contaminated catchment and interaction with bottom sediments. For the control of radiation-ecological situation in this region of Belarus and Russia a wide network of supervision over radiation situation on water bodies has been created. The data of radiation monitoring of water bodies of Bryansk-Gomel-Mogilev spot within 1986-2000 have shown that mid-annual concentration Cs 137 in all controllable rivers is much lower than Republican control levels for portable water (RCL-96, 99) and lower than Sanitary-and-hygienic specifications accepted in the Russian Federation. Decrement of Cs 137 runoff through the control sites on the rivers of Dnieper-Sozh catchment on the territory of Belarus is marked too. Now in many closed water bodies located on the territory of Dnieper-Sozh catchment where the level of contamination by Cs 137 is 185 kBq/m2 are higher, volumetric activity of surface water is close to Maximum Control Levels. Levels of bottom sediments contamination on some sites in the lakes Revuchee and Svyatskoe by Cs 137 are such that they can be called low level hard radioactive waste. Concentration of Cs 137 in surface water of the lake Kozhanovskoe by 1999 has fallen up to 4,5 Bq/l. In the lake Svyatoe in 1999 - up to 10,7 Bq/l. In the lake Kozhanovskoe concentration of Sr 90 in the solution to 1999 has made 1,1 Bq/l, in the lake Svyatoe - 0,42 Bq/l. In the lakes of Dnieper-Sozh catchment very high levels of accumulation of Cs 137 in some kinds of fishes are marked. For storage, processing and transfer of the information an experimental sample of specialized computer database has been developed and approved. Specialized computer database ensures storage, representation and data exchange of radiating monitoring information between Russia and Belarus. The proposals on improvement of radiation monitoring system on the territory of Dnieper-Sozh catchment are given. (authors)
