Abstract: We report the results of experimental studies on the effect of ultraviolet (UV) radiation in a wide spectral range of 270–405 nm on bovine coronavirus. The sensitivity of bovine coronavirus to UV radiation is determined, a comparative analysis of the data is performed, and action spectra are constructed. It is shown that bovine coronavirus inactivation is possible in the UV-A range, which will make it possible to select safe radiation sources for use in public places in the presence of people.

Keywords: β-coronavirus, UV LED, photoinactivation.
