The small portion of the electromagnetic spectrum that have wavelength between 100 and 400 NM, is the ultraviolet radiation, the UV-C rays are part of the UV rays, and they are between 100 and 280 NM. The electromagnetic waves, depending on its wavelength and its wave amplitude interact the materia and generate different nature effects. Because of its powerful germicide effect is very important the UV-C with L=254 NM radiation.
The high germicide power of the UV wavelength is due to the capacity of interacting with the DNA and with the link of its components (nucleic). The DNA is a macromolecule present in every life in which is storage all the information necessary for life and reproduction. It is possible to change the DNA information using UV-C rays. These changes in the DNA chain avoid the normal cellular reproduction and it brings the cellular death.
