The data on the state of radioactive contamination of leaves of plants growing directly on the territory of the drained part of the cooling pond of the Chernobyl NPP are presented. It was shown that the main source of contamination is the root intake of radionuclides (137Cs and 90Sr). This contamination is larger in previously drained areas compared to recently exposed ones. Hot particles were found on the leaf surface by autoradiography. Their total β-activity is a few percent of the total pollution. Possible sources of hot particles – resuspension in the air in the region of the northern part of the cooling pond are discussed.

The nuclear accident at the Chernobyl NPP caused radioactive contamination of large areas of agricultural lands in the Republic of Belarus; 265 thousand hectares of the lands were withdrawn from agricultural turnover. Later 75% of these lands were transferred to forestry enterprises and environmental protection organizations. According to ecological and economic assessments of the feasibility of returning the retiring land in the Mogilev region to full economic activity based on the outcomes of comprehensive inventory of 2014-2016 only 23% of the land areas could be re-stored. At the same time, due to the irreversible radioactive decay it is possible to assess future positive changes in radiological situation and the possibility of recovering of the land, previously recognized as radioactively dangerous, and returning into the agricultural use. The issues con-sidered in the article aim at the assessment of the future changes in the levels of radiation con-tamination of local areas and shows the prospects for their further arable and meadow use.

Purpose: Retrospective analysis of the process of defining the zones of radioactive contamination zones formed after the Chernobyl accident. Results: Summary of events related to liquidation of the Chernobyl NPP (ChNPP) accident consequences is given in the context of defining the radioactive contamination zones. Experience of zoning of the territories exposed to radioactive contamination due to the Chernobyl NPP accident during 1986–2015 in Belarus and the Russian Federation has revealed the following: - Zones of radioactive contamination as a result of the ChNPP accident have been finally defined by the regulatory-legal acts only by 1991 – in five years after the Chernobyl accident; - At present, the zones of radioactive contamination zones legally correspond to the borders of settlements that were given a certain status of the radioactively contaminated territory. This leads, in particular, to paradoxical "automatic" reduction of radioactive contamination zonesareas due to abolition of settlements with no inhabitants. Absence of the established borders of radioactive contamination zones creates difficulties in substantiation of the measures related to radiation monitoring, rehabilitation of radioactively contaminated areas and their return to economic circulation. Conclusions: Experience of eliminating mitigation of the Chernobyl NPP accident consequences shows that the absence of modern and scientifically justified procedures of defining the borders of radioactive contamination zones results not only in an inadequate assessment of the scales of consequences, but also does not allow effective differentiating the inventory and scale of necessary measures on population protection.
