In this work, based on experimental ground-based observations of the intensity and spectrum of solar radiation in the UVB range in the city of Tomsk (56°29´ N, 84°56.89´ E) from 26.03.2020 to 26.03.2021 and analysis of works on the structure and chemical molecular composition of SARS-CoV-2, primary photoacceptors and spectra of photobiological inactivation of the SARS-CoV-2 molecular structures (genome and S-thorn) by UVB radiation were determined for the first time.


COVID-19, SARS-CoV-2, spectra of photobiological action, photoacceptor molecules, active centers, RNA, S-protein, guanine, tryptophan, hydroxyl molecule
