The location of 'far-UVC' radiation (200-235 nm) in the electromagnetic spectrum. Far-UVC is a type of ultraviolet germicidal irradiation being studied and commercially developed for its combination of pathogen inactivation properties and reduced negative effects on human health when used within exposure guidelines.
A low-pressure mercury-vapor discharge tube floods the inside of a biosafety cabinet with shortwave UV light when not in use, killing microbes on irradiated surfaces. Ultraviolet germicidal irradiation (UVGI) is a disinfection technique employing ultraviolet (UV) light, particularly UV-C (180–280 nm), to kill or inactivate microorganisms ...
UV Waterworks uses the UV light emitted by a low-pressure mercury discharge (similar to that in a fluorescent lamp) to disinfect drinking water. Effective disinfection at affordable cost is the primary and most important feature of UV Waterworks—allowing an entire system (including costs of pumps, filters, tanks, housing-structure ...
Pathogen reduction using riboflavin and UV light is a method by which infectious pathogens in blood for transfusion are inactivated by adding riboflavin and irradiating with UV light. [ 1 ] [ 2 ] [ 3 ] This method reduces the infectious levels of disease-causing agents that may be found in donated blood components, while still maintaining good ...
Low power consumption of semiconductors introduce UV disinfection systems that utilized small solar cells in remote or Third World applications. [2] By 2019, LEDs made up 41.4% of UV light sales, up from 19.2% in 2014 [3] The UV-C LED global market is expected to rise from $223m in 2017 to US$991m in 2023. [4]
The innovative multi-slit spectrograph will allow scientists to exploit the properties of the light from the Sun to determine detailed diagnostics of the plasma (or ionized gas) in the Sun’s atmosphere, including temperature, velocity and turbulent motions, over active region size fields-of-view within 8 to 20 seconds.
