Upper-Room Ultraviolet Germicidal Irradiation (UVGI)
网页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 …
Ultraviolet germicidal irradiation - Wikipedia
网页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 inhibiting their capacity to carry out vital functions.
Ultraviolet light can kill almost all the viruses in a room. Why isn’t ...
网页2024年1月17日 · The technology is called germicidal ultraviolet light (GUV), and in particular, a relatively novel kind of ultraviolet light often denoted as “far-UV.” “We have so much data suggesting that...
What is Germicidal Ultraviolet? - Ultraviolet.com
网页What is germicidal ultraviolet? UV-C light is germicidal – i.e., it deactivates the DNA of bacteria, virus and other pathogens and thus destroys their ability to multiply and cause disease.
Germicidal Ultraviolet Light | Harvard Medical School Center for …
网页For years, germicidal ultraviolet light (GUV) has been a powerful tool for the prevention of tuberculosis. It is a cost-effective intervention that is safe and supported by a breadth of evidence that has accumulated over decades.

网页2023年10月17日 · While useful for killing pathogens including SARS-CoV-2, 222-nanometer UV lights may produce harmful compounds in indoor spaces, and should be used with ventilation, MIT researchers have found.
Hospital surface disinfection using ultraviolet germicidal …
网页Ultraviolet germicidal irradiation (UVGI) technologies have emerged as a promising alternative to biocides as a means of surface disinfection in hospitals and other healthcare settings. This paper reviews the methods used by researchers and clinicians in deploying and evaluating the efficacy of UVGI technology.
Germicidal Ultraviolet Air Treatment - Department of Energy
网页Germicidal ultraviolet (GUV) radiation, also known as UV germicidal irradiation (UVGI), is a method of air and surface treatment that may be more effective and energy efficient to reduce airborne disease transmission than alternatives such as energy-intensive high-ventilation solutions.
Germicidal UV Sources and Systems - PMC - National Center for ...
网页Germicidal ultraviolet (GUV) emission or radiation encompasses a continuous range of UV wavelengths from 200 to 280 nm, which upper limit is identical to UV‐C region as defined by the CIE.
What is Upper-Room Ultraviolet Germicidal Irradiation (UVGI)?
网页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.
