Ultraviolet-C (UV-C) refers to a specific range of ultraviolet radiation with shorter wavelengths than those of visible light. UV-C radiation spans the electromagnetic spectrum with wavelengths between approximately 100 and 280 nanometers. UV-C is categorized as germicidal ultraviolet, and its high-energy photons have the ability to disrupt the DNA and RNA of microorganisms, including bacteria, viruses, and fungi.
Key points about UV-C radiation include:
Germicidal properties: UV-C radiation is widely recognized for its germicidal properties. It has the ability to inactivate or destroy the DNA and RNA of microorganisms, preventing them from reproducing and functioning properly.
Disinfection applications: UV-C is commonly used for disinfection purposes in various settings, including healthcare facilities, laboratories, water treatment plants, and air purification systems. It is an effective method for sterilizing surfaces, air, and water.
Lethal to microorganisms: UV-C light is lethal to a wide range of microorganisms, including bacteria, viruses, and mold spores. The damaging effects on their genetic material disrupt their ability to replicate and cause infections.
UV-C lamps and devices: UV-C lamps and devices are designed to emit UV-C radiation for disinfection purposes. These devices are used in various applications, such as sanitizing surfaces, disinfecting air in HVAC systems, and sterilizing water in treatment facilities.
