Some Results of Radioecology Monitoring of Black Earth Soils of Georgia

Abstract

Based on radioecological monitoring data, the average content of ¹³⁷Cs and ⁹⁰Sr in 2019-2023 in the black earth soils of Georgia was studied. The obtained results are marked with the corresponding coordinates and given on the map. The average content of ¹³⁷Cs in black earth soils was determined to be 13.9 Bq/kg. The standard deviation is 14.0 Bq/kg. The content of ¹³⁷Cs in almost 95% of black earth soils does not exceed 32 Bq/kg. The average content of ⁹⁰Sr in soils is 4.1 Bq/kg. The highest ¹³⁷Cs contamination is recorded in the Samtskhe–Javakheti region of Georgia (Akhalkalaki, Akhaltsikhe, Vale, Ninotsminda, Adigeni, Aspindza, Akhaldaba). Radionuclides in the mentioned soils, namely ²²⁶Ra content is 23 Bq/kg, ²³²Th is 31 Bq/kg. As for ⁴⁰K-500 Bq/kg. The role of long-term decay products ²¹⁰Pb in the contamination of agricultural products is discussed.
