What is the Meaning & Definition of UV

Ultra violet radiation or UV radiation is called electromagnetic radiation with wave length is comprised approximately between 400 and the 15 nm. Its name comes to mind because its range starts from shorter wavelengths that individuals identify as the color violet. This type of radiation can be produced by the Sun's rays and most importantly, which produces different and very serious effects on health.
The first detection of this type of radiation was achieved thanks to the experiment that development at the beginning of the 19th century the German physicist Johann Ritter, who checked darkening of silver salts to be exposed to the light of the Sun.
The main use given to the radiation that concerns us is the methodology of sterilization, along with infrared rays, since it is able to remove any bacteria and viruses without leaving residues, in contrast to what happens with chemicals.
In the meantime, is located in study a second application that can be really useful, the UV sterilization in milk as an alternative to the traditional process of pasteurization of the same.
But with some advantage by the mentioned applications discussed, UV radiation causes certainly harmful effects on the health of human beings, especially in the skin of those who are exposed too much and at times contraindicated to the rays of the Sun.
Skin cancer, wrinkles, premature aging of the skin, staining and loss of elasticity are some of the most important damage.
