If not used or implemented properly, direct exposure to germicidal UV light can have harmful effects on both materials and people. Excessive exposure to UV-C light can harm humans in a variety of ways, including damaging the eyes and skin. However, when used in the form of a UV lamp or bulb and kept away from skin or eyes, UV light is safe. Scientists have discovered the bactericidal power of ultraviolet light and have harnessed it to manufacture a bulb that emits powerful but safe UV rays, in addition to disinfecting surfaces and contaminating the air.
It is important to be aware that not all UV products are safe or effective. It is essential to trust the company you're buying from. While you should never illuminate your skin or eyes with UV lamps, UV light is safe to purify in the home if installed by a professional. Some companies are installing UV portals that radiate people as they pass through them.
While this device may not cause much damage or damage to the skin in the few seconds it passes through the portal, it is likely that the low dose administered and the possibility of disinfecting clothes will not be effective in stopping the transmission of the virus either. Ultraviolet light and radiation are dangerous when they are powerful rays that occur in nature and come into contact with the skin or eyes. After use, UV robots or human-controlled machines designed to fit in vehicles or airplanes move across surfaces where light can reach and disinfect them. This could allow the tool to be used in many more places than are currently used with UV lights, potentially having widespread effects and reducing the spread of many infectious diseases. UV light has a long history as a disinfectant and UV light makes the SARS-CoV-2 virus, which causes COVID-19, easily harmless. UV lights can be components of mobile machines, whether robotic or controlled by humans, that disinfect surfaces.
Airlines could also use UV technology to disinfect aircraft air or use UV lights in bathrooms between uses. UV irradiation consists of wavelengths between 100 and 400 nanometers, which lie just beyond the violet part of the visible light spectrum and are invisible to the human eye. As an environmental engineer who studies ultraviolet light, I have observed that UV rays can be used to reduce the risk of transmission through both routes. Artificial UV light sources designed for disinfection emit light within the UV-C range or in a broad spectrum that includes UV-C. Far UV light effectively inactivated influenza viruses, approximately as effectively as conventional germicidal UV light. As more studies on faraway UV-C radiation demonstrate that exposure to human skin is not dangerous and if studies on ocular exposure show no harm, it is possible that validated remote UV-C lighting systems installed in public places may help control the transmission of the SARS-CoV-2 virus and other potential airborne viral pathogens, both now and in the future.
In addition, air conditioning systems can contain UV light sources to disinfect the air that circulates through the ducts. Overall, when used correctly, UV light installation is safe for humans. It is important to trust the company you're buying from and make sure you follow all safety instructions when using any type of artificial ultraviolet light source.
