The paper outlines a targeted remediation system for 71 rural settlements in five southwestern districts of the Bryansk region affected by the Chernobyl accident. Remediation strategies have been developed through a comprehensive assessment of the current radiation and demographic situation. This analysis also considered the economical use of the territory and the optimization of applying 7 remediation technologies, using computer geoinformation decision-making support systems ReSCA and GISDSS. Two approaches to restoring rural settlements are presented, considering the costs of implementing remediation technologies and their acceptability to the public. The assessment was conducted locally for each settlement with a population exposed to a dose of more than 1 mSv/year, as well as globally, encompassing five districts and the region as a whole. The calculation determined that the costs of implementing remediation technologies to reduce public exposure were estimated to be in the range of 1.23 – 1.33 billion roubles. The estimated averted collective dose from the implementing developed strategies was found to be between 79 – 88 man-Sv, with an average cost of 15.1 – 15.6 million roubles per man-Sv. It has been observed that over the last 15–20 years, the cost of restoring settlements has increased by 4.7 times, while the potential savings in residents’ collective dose have decreased by 35%. Agricultural technologies aimed at reducing the internal exposure dose of residents keep the maximum effectiveness in decreasing public doses. These technologies include surface improvement of pastures and the use of ferrocene-containing medicines for cows. 10 rural settlements and technologies have been identified as having the greatest impact in reducing the cost of averted dose for the public.
