Effects of Large-Scale Wildfires on the Redistribution of Radionuclides in the Chornobyl River System.

ABSTRACT: Wildfires in radiologically contaminated areas raise significant concerns due to potential radionuclides redistribution and increased public radiation exposure. This study examined the impact of the 2020 Chornobyl wildfire on the redistribution of radionuclides, specifically ¹³⁷Cs and ⁹⁰Sr, in the Chornobyl River system. We determined the quantities and speciation of ¹³⁷Cs and ⁹⁰Sr in charred residues and soil after wildfires and analyzed the riverine concentrations of these radionuclides based on long-term monitoring data. Our findings indicate that the inventories of ¹³⁷Cs and ⁹⁰Sr in the charred residues and soil decreased with increasing distance from the nuclear power plant, which is consistent with the initial depositi
