UVC germicidal lamps used in hospitals operate at a wavelength of approximately 253.7 nanometers, which is specifically chosen because DNA and RNA absorb this wavelength most effectively; when UVC light penetrates microorganisms, it damages their genetic material, preventing reproduction and killing the germs within seconds. However, since human cells also contain DNA, direct UVC exposure poses serious risks to human skin and eyes, which is why healthcare workers must immediately evacuate the room when these lamps are activated.

The Real Reason Nurses Leave After Turning On UVC Lights ☢️ #shorts #viralshortsAjouté :
Why do these nurses run away after turning on the UV lamp as if a bomb has been activated? Because if you stay in that room for too long, not only the germs, but your skin and eyes can also be damaged.
>> [music] >> Usually UVC germicidal lamps are used in hospitals whose wavelength is around 253.7 nanometers. And this is not a random number. Scientists have discovered that DNA and RNA absorb this wavelength the most. When this light falls on microorganisms, its energy can penetrate directly under their cell wall. And as soon as the lamp is on, the genetic material of these bacteria begins to get damaged in a few seconds.
Basically, germs can survive because of this light, but for a short time, but they can't reproduce.
But the problem is that human cells are also made up of DNA.
>> [music] >> That's why direct UVC exposure is dangerous for humans, especially for eyes and skin. That's why nurses run away as soon as they turn on the lamp.
