Keywords: plant, radioactivity, destruction of regularities, low level anthropogenic impact
Abstract: The findings from long-term field studies on biological effects in plant populations inhabiting radioactively contaminated territories contrast in levels and compositions of dose-forming radionuclides are presented. Plant populations developing under radioactive impact show enhanced frequencies of gene and chromosome mutations, and their reproductive potential is inferior to reference populations. Even relatively low levels of technogenic impact are able to increase genetic diversity and destroy regularities inherent for intact populations. Chronic radiation exposure from a certain level appears to be an ecological factor changing genetic structure of wild populations. Data presented indicate the presence of adaptation processes in plant populations in territories with technogenic impact. Under ecological stress, there are selection processes for resistance improvement in plant populations. But an appearance and rate of this process can essentially differ in dependence on radioecological conditions.

Keywords: forest, radiological division, radionuclides, rehabilitation, social and economic values
Abstract: Reviews scientific principles of specified radiological division (zoning) of forests contaminated by radionuclides due to the Chernobyl accident. Presents detailed ecological and silvicultural characteristics of radio-ecological regions. Suggests general classification of forest ecosystems on different groups of radioecological stability, based on the duration of rehabilitation of social and economic values and resource potentials of the forests after the radiation exposure.

Abstract: Presents forecast of maximum permissible levels of 137Cs contamination on agricultural land, on which the it is possible to obtain products that meet current standards, at different levels of protective measures in the contaminated areas. On the example of south-western districts of the Bryansk region an assessment is given on the production of radioecologically appropriate crop and forage, in the period after the land was contaminated by radioactive fallout.

Keywords: plant, accumulation, estimation method
Abstract: A method is founded on consideration of soil as three-phase system where soil solution reaction (pH), absorbing capacity (E) and content of organic matter (OM) are the main characteristics. The method of complete estimation of soil properties (CESP) for quantified analysis of radionuclide soil-to-plant TF dependence on soil properties is grounded and proposed. The area of an effective section (relative units)2 calculated as an area of the triangle with apexes lying in co-ordinates of normalised vectors pH, E and OM in three-dimensional space for complete estimation is used. It is shown that the dependence of Cs TF to various crops on CESP can be approximated by equation of power law.

Keywords: chromosomal aberrations, polluted water, Asellus aquaticus, ionizing radiation
Abstract: Elevated frequency of chromosomal aberrations revealed by anatelophase method in ponds and lakes corresponds to higher degree of anthropogenic pressure. Data obtained are compared with the influence of low-dose of ionizing radiation. Validity of the model for estimation of pollution degree and its mutagenic influence risk for human being is discussed.

Keywords: peaceful underground nuclear explosion sites “Craton-3″ and “Crystal”, 137cs
Abstract: In this paper, results are reported on the concentrations and activity ratios of 137Cs, 239+240Pu and 238Pu in soils, lichen and bottom sediments collected at the peaceful underground nuclear explosion sites “Craton-3″ and “Crystal” (Republic of Sakha (Yakutia), North-East Siberia). At the “Craton-3″ site, 239- 240Pu concentrations in the range 6.2 mBq/g to 5.9 Bq/g in surface soils (0-5 cm) and 239+240Pu concentrations up to 7.4 Bq/g in lichen were observed. The 137Cs concentration in measured soils range from 0.52 to 216 Bq/g for the near-plume and from 1.65 to 21.5 Bq/g for the far-plume. In lichen, 137Cs concentration varied from a global background level up to 251 Bq/g. Radioactive contamination at “Crystal” demonstrates an extremely irregular distribution of 239,240Pu and 137Cs in environmental samples taken at locations within 150 m radius of the site. Further work on compiling detailed maps of radioactive contamination of the territory around “Craton-3″ and “Crystal” is discussed.
