Ultraviolet germicidal irradiation - Wikipedia
Ultraviolet germicidal irradiation (UVGI) is a disinfection technique employing ultraviolet (UV) light, particularly UV-C (180–280 nm), to kill or inactivate microorganisms. UVGI primarily inactivates microbes by damaging their genetic material, thereby …
About Germicidal Ultraviolet (GUV) | Ventilation | CDC
2024年10月4日 · Germicidal ultraviolet (GUV), otherwise known as ultraviolet germicidal irradiation (UVGI), is the use of ultraviolet (UV) energy to kill viral, bacterial, and fungal organisms in the workplace. GUV is best used as part of a layered approach to reducing exposures to airborne pathogens, along with other strategies such as ventilation systems.
What is Upper-Room Ultraviolet Germicidal Irradiation (UVGI)?
2024年8月27日 · Learn how a professionally designed system of ultraviolet germicidal irradiation (UVGI) that is well installed and maintained can effectively kill the virus that causes COVID-19 and help protect people from the disease indoors.
The History of Ultraviolet Germicidal Irradiation for Air …
Ultraviolet germicidal irradiation (UVGI) is an established means of disinfection and can be used to prevent the spread of certain infectious diseases. Low-pressure mercury (Hg) discharge lamps are commonly used in UVGI applications and emit shortwave ultraviolet-C (UV-C, 100–280 nanometer [nm]) radiation, primarily at 254 nm.
