Abstract
Provided are an inactivation method and an inactivation system designed to produce a desired inactivating effect with increased reliability using ultraviolet light that has an extremely small influence on the human body. A method for inactivating bacteria or viruses in a space defined includes a step of irradiating of an inner wall surface, a floor surface in the space or a surface of an object disposed in the space where a specified substance displaying at least one of antibacterial and antiviral characteristics is present with ultraviolet light having a wavelength within a range of 190 nm or more and less than 240 nm.

A method for inactivating bacteria or viruses in a space that is defined, the method comprising a step (A) of irradiating of an inner wall surface, a floor surface in the space or a surface of an object disposed in the space where a specified substance displaying at least one of antibacterial and antiviral characteristics is present with ultraviolet light having a wavelength within a range of 190 nm or more and less than 240 nm.
A system for inactivating bacteria or viruses on an object to be treated in a space that is defined, the system comprising:
- an antibacterial layer formed on a surface of the object, the antibacterial layer containing a specified substance that displays at least one of antibacterial and antiviral characteristics;
- and
- a light source device mounted on a ceiling or a wall surface in the space to emit ultraviolet light with a wavelength within a range of 190 nm or more and less than 240 nm toward the antibacterial layer on the object.
