UV rays from the sun
Contains 3 types of UV
Solar radiation is an important source of radiation that reaches Earth. It consists of radiation.
UVA UVA
(Long wave UVR or Black light)
The wave range 400-315 nanometers is light that is transmitted closest to the earth's surface. If touched for a long time Will cause damage to the skin. It is the cause of hyperpigmentation or wrinkled skin.
UVB UVB
(Middle UVR or Sunburn radiation)
Wave range 315-280 nanometer
It damages DNA and can cause skin cancer.
UVB UVB
(Middle UVR or Sunburn radiation)
Wave range 280-170 Nanometers are energetic short-wave radiation.most places It is harmful to all types of living things, includingable to kill germs
Adopting high intensity UVC light It is used in equipment for disinfection in various places.
For example, on buses or medical equipment in hospitals, there will be a UVC light irradiator for cleaning.
Most use UVC light bulbs, commonly called Germicidal lamp is a mercury vapor lamp with low pressure inside the lamp. Most give UVC rays at a wavelength of 254 nm and secondly they give UVC rays at a wavelength of 185 nm. The sterilization time ranges from 30, 60 seconds to 30 minutes, depending on the amount of UVC rays and the length of time used.
UV and disinfection
Would it be better? If bothsafe and protected
It is a pleasure because a team of doctors and researchers from Columbia University
Experiments were conducted using light with a wavelength of 222 nanometers to kill viruses. which the research results
can be sterilizedup to percentage 99.9 %
Columbia University
Far-UVC light (222 nm)
Safety of Far-UVC Light (222nm)
There are also various research works on the safety of UVC by researchers from leading academic institutions in many sources. Did research and found that Far UVC Light (222nm) can kill viruses and other germs. Without harming the skin and eye tissue. Because of the light at this level Cannot penetrate the upper layers of the epidermis, including the tissue of the eyeball (tear layer).
