One of the measures to eliminate the consequences of the Chernobyl accident was the exclusion of highly contaminated land from agricultural use. Due to the positive dynamics of the radiation situation, the issue of land return becomes relevant. However, in the period of exclusion of these lands the land clearance degradation processes were developing. The second part of the article is devoted to the issue of economic evaluation of the expediency of land return and the mutual coordination of the results of separate stages of complex ecological and economic evaluation. The research was carried out in Mogilev branch Institute of radiology (Republic of Belarus).

One of the measures to eliminate the consequences of the Chernobyl accident was the exclusion of highly contaminated land from agricultural use. During the natural decay of radionuclides there is a decrease in the activity of 137Cs and 90Sr in the soil. The issue of land return becomes relevant. The article describes the main stages of formation of the system of criteria and indicators of ecological and economic evaluation of the expediency of land return. The first part of the article is devoted to the issue of radiological evalation.

The impact analysis of low doses of ionizing radiation on the breathers in natural populations is an important part of radiobiological studies of non-human biota. The main aim of our studies was to investigate some cytogenetic, morphological and reproductive rates of the common reed (Phragmites australis (Cav.) Trin. ex. Steud.) from different water bodies within the Chernobyl accident exclusion zone. The absorbed dose rate for littoral emergent plants in sampling water bodies was varied from 1.3E−02 to 1.6E−01 Gy/h. The rate and main types of chromosome aberrations in roots meristems, morphological damages in seed germs, as well as rates of germinating ability and power were analyzed. There were registered rather low rate of germinating ability (14–48%) and germinating power (<1) of seeds from all sampling water bodies with high levels of radioactive contamination in comparison to control ones. Against the general suppressed background the effect of relative stimulation of more affected seeds was observed. With increase of absorbed dose in range of 1.3E−02–1.6E−01 Gy/h the number of germinated seeds was increased. At the same time the number of morphological damages of seeds was increased as well. There was determined the positive correlation between absorbed dose rate and chromosome aberration rate in roots of the common reed from sampling water bodies. The highest rate of chromosome aberrations (up to 17%) were registered in plants with high level of morphological deviations in seeds germs. The data obtained from the complex analysis of natural populations of the common reed from the radioactive contaminated water bodies testify about rather high level of genetic efficiency of low doses of long-term exposure.

Purpose. To determine the content of radionuclides 137Сs, 90Sr and heavy metals in water bodies within the boundaries of settlements of Kamyn-Kashirsky, Lyubeshivsky and Manevychi administrative districts of Volyn region. Methods. During the expedition and laboratory work, standard methods of sampling, preparation and measurement of samples were used according to the current methods of radiochemical, radiospectrometric, ichthyological, hydrochemical, statistical analyses, etc. The determination of the total content of heavy metals was performed in laboratory conditions by conventional methods. Results. The research is based on its own analyses, as well as the stock materials of the Scientific Information Center for Water Management and Ecological Monitoring and Optimization of Water Use. Features of 137Сs, 90Sr radionuclides distribution in reservoirs (water, sediments, fish, birds) within the zone of radioactive contamination in Volyn Region are considered. The maximum concentrationі of 137Сs, 90Sr in the studied area were determined. The anthropogenic impact and excess of the maximum permissible concentrations and maximum permissible levels of toxic substances in the ecosystem links of certain water bodies of the partially contaminated region are identified. Conclusions. As a result of the study on the level of concentrations of 137Сs and 90Sr and heavy metals in water (within the boundaries of settlements) of the investigated area, it was found that reservoirs in village of Prylisne, village of Velyka Osnytsya, village of Cherevakha in Manevitsky District, village of Nuyno in Kamin-Kashirsky District and the village of Vetly in Lyubeshiv Administrative Distict are affected by the highest concentrations of 137Сs and 90Sr. The significant content of heavy metal salts is recorded in the reservoirs, namely in the village of Serhiv – lead, village of Prylisne in Manevytskyi District– zinc, cadmium; in the village Berezna Volia in Lyubeshiv District – copper; in the village of Nuyno in Kamin-Kashirsky District – lead.
