UV-C (254 nm) lethal doses for SARS-CoV-2

•We developed a controlled assay to investigate the UV-C inactivation kinetics for SARS-CoV-2.•We established the UV-C lethal doses for the virus in vitro.•LD90 for SARS-CoV-2 was reached at 0.016 mJ/cm2.•LD99.999 was achieved at 108.714 mJ/cm2 with exposure time less than 50 s.
