Ultraviolet radiation

What is it?

The ultraviolet light is a part of the electromagnetic radiation placed below the visible light, with wave length below 400 nanometers; it is classified in three divisions depending on its effect: UV-A, UV-B and UV-C.

UV-C is the section between the 200 and 280 nm; its uses go to the superficial cure in the industry, up to germicidal applications eliminating effectively virus and bacteria.

What is the influence of the light UV in the microorganisms?

The bacteria, virus, fungi... (see organisms) are vulnerable to the effects of the ultraviolet light (UV-C): In the wavelengths next to 253,7 nanometers, the UV acts as germicide spoiling the genetic material (DNA) of these microorganisms, incapacitating them for its reproduction and infection.

These microbes are, in big number causers or propagators of diseases and illness, as: Allergies, flu, gastroenteritis, salmonelosis...

The use of efective systems of germicidal radiation reverberates directly in the quality of life of the people, there where they could develop germs; and it is necessary in places where the sterilization of the work environment is obligatory. For example: laboratories, hospitals, manipulation of food, medicines... (see uses)
