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 …

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.

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.

This book is a comprehensive source for technical information regarding ultraviolet germicidal irradiation (UVGI) and its application to air and surface disinfection for the control of pathogens and allergens. The primary focus is on airborne microbes and surface contamination applications for hospitals, commercial facilities, and residential ...

2024年12月5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.

2009年7月9日 · Ultraviolet Germicidal Irradiation (UVGI) is electromagnetic radiation that can destroy the ability of microorganisms to reproduce by causing photochemical changes in nucleic acids. Wavelengths...

2021年4月9日 · Ultraviolet germicidal irradiation, or UVGI, is the use of ultraviolet (UV) energy to kill viral, bacterial, and fungal organisms. UVGI fixtures produce UV-C energy, which has shorter wavelengths than more penetrating UV-A and UV-B rays and pose less risk to human health.

2014年6月6日 · The purpose of this document is to examine the different parameters necessary for an effec­tive upper-room UVGI system and to provide guidelines to healthcare managers, facility designers, engineers, and industrial hygienists on the parameters necessary to install and maintain an effective upper-room UVGI system.

2022年1月10日 · Overview: Ultraviolet germicidal irradiation (UVGI) has been used for decades to purify air in hospitals and labs that need to ensure microbes aren’t introduced or distributed by the ventilation system. UVGI is also used in a less intense installation to …

Safety of Upper-Room Ultraviolet Germicidal Air Disinfection for Room Occupants. The impact of far-UVC radiation (200-230 nm) on pathogens, cells, skin, and eyes – a collection and analysis of a hundred years of data. Balancing the Risk of Eye Irritation from UV …
