Ultraviolet C (UVC) light, a segment of the ultraviolet spectrum, plays a crucial role in disinfection and sterilization processes. With wavelengths ranging from 100 to 280 nanometers, UVC radiation is effective in inactivating microorganisms such as bacteria, viruses, and fungi. This is achieved through the absorption of UVC light by the nucleic acids within these pathogens, leading to the formation of pyrimidine dimers. These dimers disrupt the DNA replication process, rendering the microorganisms incapable of reproduction and effectively neutralizing their threat.
UVC technology has gained significant traction in various applications, including water treatment, air purification, and surface disinfection, especially in healthcare settings where the risk of infection is heightened. Unlike UVA and UVB rays, UVC does not reach the Earth's surface due to atmospheric absorption, making it safe for use in controlled environments. However, precautions must be taken to prevent exposure to human skin and eyes, as UVC can cause severe damage. As the world continues to face emerging infectious diseases, UVC disinfection technologies increasingly represent a critical component in public health strategies and infection control measures.
