Ultraviolet light is subdivided into UV-A (315 to 400 nm), UV-B (280-315 nm), and UV-C (100-280 nm). Artificial UV used for disinfection is almost always UV-C, so UV and UVC are often used ...

Far-UVC light dramatically reduced airborne virus levels in a room where people were working, in the first study of the new air disinfection technology outside of an experimental setting.

How Far-UVC light could be key in curbing the next airborne pandemic 03:31. ... there's an experimental room that simulates real life and controls for conditions like humidity and airflow.

Ultraviolet C light at 254 nanometers is the standard for eliminating airborne and surface pathogens from bacteria, viruses and mold, according to the National Center for Biological Information ...

Light with such a wavelength — called far-UVC, from the ultraviolet portion of the electromagnetic spectrum — is deadly for microbes, researchers are learning, but appears safe for human beings.

Hospitals have long used ultraviolet light to zap viruses, but the devices were too expensive for businesses and schools. Spurred by the pandemic, an unlikely trio started R-Zero to develop a ...

Recently, light at 222 nm has been suggested for whole-room disinfection because the wavelength is reported to be safer for humans. However, UVC light can set off many reactions. For example, this ...

Using a room-sized chamber that allowed three Air-Changes-per-Hour (ACH) and five filtered Far-UVC lamps, they continuously released aerosolized staphylococcus aureus into the space and conducted ...

A investigated skin cancer risk in a large cohort of patients treated with ultraviolet light therapy between May 1977 and November 2018. Patients were treated with narrowband UVB (NB-UVB ...

Conventional UVC light is currently used to sanitize surfaces in places like hospitals, ... there's an experimental room that simulates real life and controls for conditions like humidity and airflow.
