Radioactively contaminated objects (RZO) - Building materials and constructions, technical equipment and tools that are contaminated by Chernobyl contamination or characterized, formed as a result of its former normal operation, and need organizing environmentally friendly treatment of after removal. RZO formation is the result of three major areas of modern activities in the exclusion zone aimed at clearing its territory of radioactive materials anthropogenic and putting them in a controlled state, namely the transformation of the "Ukryttya" into an ecologically safe system; decommissioning of Chernobyl; work to minimize the consequences. RZO total amount that will be generated during the conversion activities of "Ukryttya" into an environmentally safe system, as well as activities on decommissioning Chernobyl, are difficult to predict and account for tens of thousands of tons of different origin and extent of radioactive contamination of materials. Much of RZO is a valuable industrial raw materials and ensuring the decontamination of reusable industry is an important scientific and technical problem. In addition, partial deactivation RZO potentially fall into the category of long-lived high-level radioactive waste, will lead to significant cost savings for their subsequent storage by transfer to less hazardous category of radioactive waste. The problem of determining the feasibility of implementation of decontamination RZO is that a positive decision to analyze a large number of radiological, technical and economic factors which, given the diversity of origins and properties RZO have wide amplitude values. You must also consider the fact that over a long period of work on the transformation of "Ukryttya" (several decades) possible improvements in cost performance as deactivation due to introduction of new technologies, and by improving and reducing the cost of already known. The work is dedicated to the definition and analysis of a list of initial data necessary for the formalization of the decision on the feasibility of implementation of decontamination RZO to be formed during the transformation of the "Ukryttya" into an environmentally safe system, as well as activities on decommissioning Chernobyl.
