How the cumulative light amount is calculated?

The required irradiation amount and conditions by ultraviolet varies depending on the targeted type of bacteria, virus, and other microorganisms. In general, the disinfection effect is determined by totaling (the cumulative light amount or ultraviolet dose) the light strength (intensity) and the time UV light is shone onto the object (irradiation time). The longer irradiation time, the more the cumulative light amount increases, resulting in a greater disinfection effect. Conversely, a high output ultraviolet intensity is required when disinfecting is required for a short time.
