People have been leaning to this high-tech solution in lieu of eliminating germs and bacteria.
A toothbrush sanitizer is a device used to disinfect the tooth brush by applying short-wavelength ultraviolet (UV-C) light to kill or inactivate microorganisms. Studies in dental journals demonstrate that UV sanitizers effectively kill bacteria and microorganisms, but other forms of sanitizing, using common household products, were found to be equally or more successful at eliminating ...
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.
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]
These lamps emit ultraviolet light with two peaks in the UVC band at 253.7 nm and 185 nm due to the mercury within the lamp, as well as some visible light. From 85% to 90% of the UV produced by these lamps is at 253.7 nm, whereas only 5–10% is at 185 nm. [38] The fused quartz tube passes the 253.7 nm radiation but blocks the 185 nm wavelength.
UV-C light being used to sterilize equipment in a laboratory. UV-C cannot be used to disinfect people as it can damage the skin and eyes. Exposing people to sunlight will not prevent or cure COVID-19. It has been falsely claimed that UNICEF said so, in coronavirus prevention guidelines; UNICEF officials refuted this.
