Regarding the possible impact of forest fires on the radioactive pollution of groundwater in the chornobyl exclusion zone.

ABSTRACT: Wood contamination in the Chornobyl Exclusion Zone (CEZ) with ¹³⁷Cs and ⁹⁰Sr reaches tens of kBq/kg. Fires are natural disasters that fundamentally alter the forest ecosystem. The largest fires in the CEZ occurred in 2020 at the temporary radioactive waste storage facility (PTLRW) known as "Red Forest", where the peak of ⁹⁰Sr activity in wood was recorded. Subsequently, the level of ⁹⁰Sr in groundwater samples from observation wells in this section of the CEZ increased by 2 to 60 times, rising from approximately 2 to about 180 Bq/l beginning in late 2022. The laboratory experiment utilized typical pinewood and forest litter samples. Laboratory studies show that burning 1 kg of dry pinewood produces approximately 2.8 g of ash, with a concentration
