[Development of a strategy for countermeasures application aimed at remediation of consequences of radioactive contamination of forest ecosystems].
The radiation situation has been assessed in forest ecosystems of the most affected by the Chernobyl accident region of the Russian Federation--Novozybkov district of the Bryansk region. Using a set of migration models and methods for estimating doses of external and internal irradiation of the population, predictive calculations have been made that demonstrated a need to implement countermeasures in forest ecosystems of the region. A strategy of countermeasures application was developed based on a conservative approach, which postulates priority of observance of the sanitary-hygienic standard--permissible exposure level for the population and need for invoking the economic indicators to optimize countermeasure option. The effectiveness of countermeasures has been assessed based on a multicriterium approach using a system of decision making PRIME Decisions. The derived results have been formalized as indices of countermeasures effectiveness for different combinations of criteria.
