Decision support on risk based land management and sustainable rehabilitation of radioactive contaminated territories

The general questions of decision-making support on Risk Based Land Management O^BLM), including key factors and components, range of existing decision support and analytical tools and techniques are considered. The characteristics and possibilities of the applied Decision Support System PRANA as a tool for decision support on RBLM and sustainable rehabilitation of radioactive contaminated territories are described. 1. DECISION-MAKING SUPPORT The topic of contaminated land has been an increasingly important one in many areas of policy, research and practice both within different countries and at international level [1,2]. Land is considered contaminated when there is a risk of unacceptable harm from pollutant during its present or intended use (see Figure 1). In scientific and technical terms contaminated land can impact on human health, quality of surface and groundwater, nature and viability of ecosystems, buildings and other materials and artefacts within the ground, and the visual amenity of an area. Decision-making, in the face of uncertainty and multiple and often conflicting objectives, is a vital and challenging role in contaminated land management. Finding sustainable technical solutions for contaminated problems is dependent on a range of parallel considerations. Decisions about which risk management option(s) are most appropriate for a particular site needs to be considered in a holistic manner. Key factors in decision making include [3,4]: driving forces for the remediation project,
