On the issue of the relationship between the characteristics of areas with dispersed radioactive contamination and the need for their remediation

Abstract

The paper considers different approaches to evaluate outcomes of remediation of radioactively contaminated sites. The following indicators are currently used: economic, social, radiological, etc. Radiological factor is most commonly used, it is based on estimated averted collective dose to population. In this case, the radiation dose depends on soil characteristics, the level of radioac-tive contamination, as well as function-based soil quality for land-use planning. The most dan-gerous option in terms of radiation dose formation in populations the planning to use contami-nated sites as an agricultural land. In order to make final decision the size of contaminated area, must be taken into account when addressing the issue of meeting needs for agricultural products. The paper presents the new method for estimating results of remediation of radioactively con-taminated sites with account of actual size of radioactively contaminated area. The method was tested in implementing federal target program “Nuclear and radiation safety for 2016-2020 and the period up to 2030”. The method can be used for estimating efficiency of performed and planned remediation.
