About ultraviolet light
Ultraviolet radiation is made up of solar radiation whose wavelengths lie between infrared radiation and x radiation. There are three types of ultraviolet light, each with its unique wavelength range and each having a different effect on living bodies:
- - UV type C - from 100nm to 280nm;
- - UV type B - from 280nm to 315nm;
- - UV type A - from 315nm to 400nm.
These types of ultraviolet light have different effects on organisms. UVA rays have an inflammatory effect, UVB radiation has a tanning effect (by stimulating cells that determine skin pigment), UVC rays - by causing severe cellular lesions - have a destructive effect on cells.
The benefits of light have been documented since ancient times. Along with the study of microscopic organisms and diseases attributed to them, the effectiveness of ultraviolet light against pathological agents has been observed. This effect of ultraviolet radiation is especially due to type C radiation, and has had very important applications in the fields of disinfection and sterilization.
In order to destroy the microorganisms, UV rays penetrate the cell's membrane and enter the cell's body destroying the DNA, thus causing lesions that stop the bacterial activity and its ability to reproduce. By targeting cells and delivering high energy to them, UV rays destroy biological material without determining chemical reactions. The inactive microorganisms are not removed from their environment. In addition, the UV rays do not modify the particles or chemical components of the environment, whether organic or inorganic, except for living organisms that contain DNA. The environment is sterilized in direct proportion to the amount of light received. 
The ultraviolet rays' effect on bacteria: UVC penetrates the bacterial wall; its activity is focused on the cell's nucleus that contains the bacterial DNA.
The bacterial destruction as a result of UV activity: UVC rays provoke the destruction of genetic material (DNA). As a result of the DNA destruction, bacterial growth and multiplication can no longer continue. This ultraviolet ray destructive effect is the basis for the use of UV antibacterial lamps in the field of disinfection and sterilization.
