ABSTRACT The human to person transmittance of the virus is of significant concern due to the widespread mortality and morbidity, especially in the event of a pandemic. These are also major effects of seasonal influenza. Because airborne transmission appears to play an significant role in the spread of flu, efforts to avoid or disrupt the cycle by public health should be centered. Continuous study and awareness of the ways that influenza virus will transmit from person to person continues. There is debate that influenza virus is transmitted by fine airborne aerosols, ballistic penetration, or fomite touch. One technique proposed to be successful is UV radiation, known as UV-C light. UVC is a high energy light with a shorter duration, but it loses the strength faster than UVA, and UVB. UVC is a high energy light. The strongest management methods are applied. That is not just how it hits the surface of the world. The ozone layer is mostly filtered out. This is thus called safe and, for five reputed organizations and their respective goods, this research focuses on determining their significance, categories and thresholds of value. Keywords: Germicidal, UV light, Virus, Wavelength.

INTRODUCTION
UV exposure ranges between 200 and 300 nanometers and is believed to destroy the virus, which renders the virus impossible to replicate and spread. Throughout the current pandemic, the widespread adoption of this powerful UV approach is very required, but needs UV sources which emit enough UV light at high levels. While devices with these high doses currently exist the UV source is typically a high-powered, mercury-containing, high-power, short-lived, and cumbersome gas discharge lamp. The solution is to develop high-performance, energy-efficient , and environmentally friendly UV light emission diodes. Although these LEDs exist, the fact that the coating must often be invisible to UV light complicates adding a current on light pollution. The disinfecting of unoccupied space such as empty patient rooms or empty subway cars may be achieved with traditional UV light (wavelength 254 nm), although it can not be specifically exposed to such traditional UV lamps in the public sector, because that would be a danger to the safety. Researchers at Columbia University Irving Medical Center studied far-away UVC light (222 nm wavelength) in order to continuously and reliably clean inhabited indoor areas. Light of Far UVC can not reach the eye's tear layer or skin's outer dead-cell layer, thereby blocking or destroying live cells in our bodies. Scientists have shown previously that far-reaching UVC light will safely destroy influenza viruses. A recent research by Columbia University of Irving Medical Center (CIU) has shown [3] that over 99,9% of the seasonal coronaviruses in airborne droplets were destroyed in human health when subjected to a particular wavelength of ultraviolet radiation.

SIGNIFICANCE OF STUDY
In cellular RNA and DNA, high energy from shortwavelong UVC light is absorbed to destroy nucleic acids and avoid infection and replication of micro-organisms. UVC is heavily absorbed by RNA and DNA bases which, through a photodimerization method, trigger molecular structural harm. It contributes to inactivation of the virus, and it can not spread again. In absorption of UV radiation and inactivation by the infection, the nucleic acid plays a key function in the infection. The other key components of the virus particles perform comparatively small roles in UV inactivation of most viruses. www.irjmets.com
