Abstract
Provided are a method and an apparatus for inactivating bacteria or viruses attached to an object while suppressing generation of a strange odor. The method for inactivating bacteria or viruses includes a step (a) of irradiating with ultraviolet light having an optical output at a specific wavelength in a range of 200 nm to 235 nm. The step (a) is a step of irradiating with the ultraviolet light is performed so that an irradiance (X) [mW/cm] (X>0) and an integrated irradiation dose within two hours (Y) [mJ/cm] satisfy the following formula (1)0<<10.704  (1).
