The article presents the results of monitoring of bismuth-214 activity concentration in atmospheric aerosols in the atmospheric surface layer of the Sevastopol region in 2007– 2020. Bismuth-214 is a daughter product of the decay of radon-222. It is one of the main radionuclides that form the natural gamma background of the surface atmosphere. The aim of this work is to obtain quantitative characteristics of the temporal variability of the concentration of bismuth-214 in the atmospheric surface l
