Biologically Active UV Radiation in the 21st Century

Data on the ozone content in June and January of 1980 and 2100 obtained using the SOCRATES two-dimensional interactive model of the average atmosphere are presented. Based on these data, using the Fast simulation of downward UV doses, indices and irradiances at the Earth’s surface program developed at the Norwegian Institute for Atmospheric Research, the change in the main factors of biologically active solar radiation by the end of the 21st century, including data related to the formation of erythema and vitamin D in humans, is calculated. It is shown that the parameters of biologically active radiation by the end of the 21st century may change compared to 1980; however, this will not pose a significant threat to human health.
