The study presents the results of the correlation analysis for the average seasonal values of intensity of solar UV radiation (297-330 nm), as well as for the energy of the lines of solar spectral irradiance with total solar irradiance and total magnetic field of the Sun for the period of 2008-2018 (the 24th cycle of solar activity). The analysis is carried out using the spectral observations of solar UV radiation at Novolazarevskaya station (Antarctica), the SORCE spacecraft and WSO (Wilcox Solar Observatory) data. The dependence of the UVB-UVA radiation of 280-315 nm (UV-B) and 315-400 nm (UV-A) on changes in the total magnetic field of the Sun is revealed.
