Rrezet ultraviolet kanë sikurse rrezet e dritës pikën e thyerjes dhe absorbohen. Gjatësia valore e këtyre rrezeve është nga 789 tera herc (380nm) deri në 300 PHz (1nm). Energjia e një kuanti të një rrezeje është diku 3.3 eV (380nm) deri në 1000ev (1nm). rrezatimi ultraviolet është gjetur më 1802 nga J.W.Riter.
Υπεριώδης ακτινοβολία (υπέρ το ιώδες χρώμα, πάνω από τη συχνότητα του ιώδους χρώματος) ονομάζεται η περιοχή της ηλεκτρομαγνητικής ακτινοβολίας της οποίας το μήκος κύματος στο κενό κυμαίνεται περίπου μεταξύ 380 και 60 νανομέτρων (nm). [1] Υπάρχουν τρία είδη υπεριώδους ακτινοβολίας [2]:
Extreme ultraviolet radiation (EUV or XUV) or high- energy ultraviolet radiation is electromagnetic radiation in the part of the electromagnetic spectrum spanning wavelengths shorter than the hydrogen Lyman-alpha line from 121 nm down to the X-ray band of 10 nm.
Ultraviolet radiation, also known as simply UV, is electromagnetic radiation of wavelengths of 10–400 nanometers, shorter than that of visible light, but longer than X-rays. UV radiation is present in sunlight, and constitutes about 10% of the total electromagnetic radiation output from the Sun.
Ultraviolet germicidal irradiation (UVGI) is a disinfection technique employing ultraviolet (UV) light, particularly UV-C (180–280 nm), to kill or inactivate microorganisms. UVGI primarily inactivates microbes by damaging their genetic material, thereby inhibiting their capacity to carry out vital functions. [1]

A germicidal lamp (also known as disinfection lamp or sterilizer lamp) is an electric light that produces ultraviolet C (UVC) light. This short-wave ultraviolet light disrupts DNA base pairing, causing formation of pyrimidine dimers, and leads to the inactivation of bacteria, viruses, and protozoans.
