Abstract
The issue on rehabilitation of the lands that are not used in the agriculture due to 137Cs and 90Sr contamination is getting more relevant. Both government authorities and agricultural producers show attention to this category of lands. Natural processes of radioactive decay lay the groundwork for considering the possibility of using these lands. At the same time the processes accompanied by overgrowing, swamping and getting hil-lock of the areas have been taken place for a long time. Their involvement into agricultural production will acquire significant costs. In this connection, it is needful to develop a methodology for radiological and economic assessment of the land, taking into consideration the balance of the two components, where the radiological criterion should assess the level of radiation safety, which is characterized by the dose rate of gamma radiation in the area, the density of soil contamination, the compliance of the forecast contamination of the products with the republican permissible levels. The economic criterion is characterized by the period of recoupment of the costs necessary to eliminate the cultural disorder, by various types of products. To evaluate and develop the recovery strategy of the lands withdrawn from circulation in the 1990s, the relevant information on the radiological situation was required, because the latest data correspond to the time of their withdrawal or are partially lost. There was no information about the modern cultural and technical condition. This predetermined the need for an appropriate survey. As a result of a comprehensive research study, 1774.8 hecta-res or 16% of the land were recognized as suitable for returning to agricultural production.
