Calculations of UV radiation for the regions of Russia, where anomalies of the total ozone content were observed in the first quarter of 2016, are performed. Ozone depletion in the winter in the Northern regions of Siberia, even to the levels of the so-called ozone hole is not critical. However, much weaker ozone variations in the early spring can lead to dangerous levels of erythemal UV radiation, when one need in protection from ultraviolet radiation.
