Abstract
Results of the reconnаissance exploration of the abundance and distribution of radioactive chemical elements (Th, 137Cs) in various environmental components (ledge rocks, soil, bottom sediments, surface water) of Pribaikalia are presented. Wide occurrence and high variability of the concentrations of these elements in the environment, often several times higher than the regionаl background values, were demonstrated. The dual genesis of anomalous fields was established: nаtural and technogenic.
