Method for inactivating bacteria or virus, bacteria or inactivation device of virus

摘要

Problem to be solved: to provide a method and apparatus for sterilization of bacteria attached to the object or inactivation of the virus while suppressing the odor.The method of inactivation of the bacterium or the virus according to the present invention comprises a step (a) for irradiating ultraviolet light indicating a light output to a specific wavelength within the range of 200 nm to 235 nm. Step (a) is a step of irradiating the ultraviolet rays to satisfy the following equation (1): irradiance (x) [MW / cm2] (x > 0) and the cumulative irradiation dose (y) [MJ / cm2] within 2 hours.0 < y < 10.704 X - 0.373Diagram
