Abstract
Ultraviolet Radiation Decontamination is a non-contact decontamination method that emerges as a viable alternative, as it achieves rapid y efficient inactivation of viruses y bacteria, according to studies showing up to 90% deactivation of these microorganisms. When bacteria, protozoa, y viruses are exposed to ultraviolet light, they lose their ability to reproduce, unlike chemical methods used for disinfecting water, food, surfaces, or surgical items. Essentially, UV light denatures the DNA y RNA that make up the virus, disabling its replication capability. This document provides a literature review on the basics of disinfection systems using ultraviolet (UV) light. It also compares this system with other non-contact disinfection methods, such as the hydrogen peroxide vapor system, revealing that UV disinfection systems have fewer disadvantages. However, it is important to highlight that UV disinfection systems should be used without the presence of people or with personnel wearing safety garments, as UV-C radiation has harmful effects on health with direct exposure. According to the National Toxicology Program, this type of radiation is classified as a probable human carcinogen.
