When it comes to UV, you’re dealing with a type of electromagnetic radiation. Its wavelength varies between 100nm and 400nm. Also, it’s an element in the electromagnetic spectrum. UV light comprises four classes but only UVC is powerful enough to disinfect surfaces. Its wavelength ranges from 200nm to 280nm.
As such, UVC light is powerful enough to disintegrate the genetic makeup of viruses and bacteria. Since UVC from the sun is filtered out and doesn’t enter the earth’s atmosphere, we can’t rely on it.
Also, particular Coronavirus strains have existed for a short period. As such, there’s no sufficient research on the effective disinfection solution that cut across. But there’s enough evidence that UV lights have worked on several COVID-19 strains effectively. As such, it’s a powerful disinfectant.
Being a strong and effective cleaning solution, UV light is also dangerous to humans. It’s powerful enough to damage the eyes and burn the skin. As a result, it’s advisable to use it on objects or surfaces that require disinfection. Also, it’s best to allow professionals to handle it because of how harmful it can be when used incorrectly.
From a study by AJIC, UV light has the potency to kill new Coronavirus strains according to an experiment. From the results, it takes about 9 minutes to inactivate Coronavirus. For instance, the SARS-CoV-2 strain was highly susceptible to UV light. The data from the study proved it’s an effective disinfection solution for COVID-19, among other viruses and bacteria.
Further, another study by AJIC also revealed that UVC is a powerful disinfectant. In less than half a minute, UV light eliminated 99.7% of Coronavirus on the laboratory surface. And from this result, it was clear that UV light is a reliable containment solution for COVID-19. Also, people can use UV light in disinfecting both free and occupied spaces.
