A Review: Discussion of Factors Affecting the Efficacy of UV Inactivation

UV can achieve the sterilization of clean and nontoxic by-products, and the article makes clear the way in which data such as irradiance and dose are taken. The article data indicates that higher bactericidal efficacy can be achieved for most bacteria at doses of 4 mJ/cm2 for irradiance 1.0 mW/cm2 and 0.06-0.30 mW/cm2 for irradiance 11 mJ/cm2. The value of irradiance ignored the attenuation of LED during long-term use. By comparing the bactericidal effect of single layered and multi-layered bacteria, the degree of cleanliness achievable by UV bactericidal is illustrated, and it is reminded that safety protection should be taken care of during use.
