Over the past few years, UV disinfection light has gained considerable attention because of its germicidal properties. A variety of UV disinfecting devices are available for various applications. This includes the sanitization of water, air, and surfaces.

To see how UV disinfection works, let's take a closer look at it. Throughout this article, we will cover the basics of UV light. And its production, its implications, and its germicidal potential for workplace sanitation.

What is UV Light & How it's Generated?

The light that comes after violet in the light spectrum is known as "Ultraviolet Light" because it's invisible to the human eye. Bacteria and mold are more affected by UV light than visible light because of UV's high frequency. In addition to disrupting these harmful organisms at the cellular level, UV light can prevent them from reproducing. Decontamination can take place using UV light because of that.

A UV-C light beam has the highest frequency, while UV-A rays and UV-B light have lower frequencies. Bacteria and mold can only disappear by UV-C rays, which have the highest frequency.

Toxic UV radiation, but, can damage living tissue when exposed for too long. Different wavelengths and frequencies travel by electromagnetic radiation coming from the sun. The electromagnetic spectrum (EM) consists of a wide range of wavelengths. Due to decreasing wavelength and frequency, the electromagnetic spectrum can be divided into 7 regions. There are 5 types of electromagnetic radiation. These are radio waves, microwaves, infrared (IR), visible light, ultraviolet (UV), X-rays, and gamma rays.

How Does UV-C Light Technology Work:

The UV-C effect is primarily due to the use of short-wavelength and ultraviolet radiation. Which we discussed earlier, whose wavelengths range from 200 to 300 nanometers. To be able to inactivate microorganisms, the short wavelength must be able to carry a sufficient amount of energy. As a result of the application of UV-C light, the following outcomes can check below:

  • UV-C wavelengths absorb high quantities of energy into the RNA and DNA of cells.
  • Nucleic acid is damaged by this energy absorption, disrupting the DNA of microorganisms.
  • Microorganisms lose their viability when their DNA decays

Therefore, you eliminate the possibility of the microorganism spreading or infecting you in the future.

Does UV light disinfection work against COVID-19?

The ultraviolet, that is also known as UVC, has a good track record of treating diseases such as SARS-CoV-1 and MERS. Which are close relatives of SARS-CoV-2, the virus responsible for the COVID-19 outbreak. According to some studies, UVC light is likely to be as effective as SARS-CoV-2. But the majority of studies are, as far as I know, small and have not been extensively peer-reviewed, including those cited by the FDA.

According to the FDA, few scientific studies about the wavelength, dose, and UVC radiation are needed to kill the SARS-CoV-2 virus. Consequently, more research is needed before UVC lamps can be considered a reliable and safe way to kill Coronaviruses.

It is also worth noting that UV lamps continue to play an essential role within the healthcare sector for sterilization purposes. Why is this the case? Research has shown that UVC rays can reduce the transmission of superbugs by 30% (such as staph). The University of California, Irvine's distinguished professor of physics and astronomy, Chris Barty. Says that many hospitals use UVC-emitting robots to sterilize entire rooms.

The device emits UV rays when people leave the room. By adapting to the size and variables (shadows, hard-to-reach places) to emit the light for as long as needed. By using Tru-D, a type of this device, this could take about 4-5 minutes for smaller rooms like bathrooms and 15-25 minutes for larger ones.
