Here's a breakdown:
* Ultraviolet (UV): A type of electromagnetic radiation with wavelengths shorter than visible light but longer than X-rays.
* C: Refers to the specific wavelength range of this type of UV radiation.
Key Characteristics of UVC:
* Germicidal: UVC radiation is highly effective at killing bacteria, viruses, and other microorganisms.
* Non-Ionizing: Unlike X-rays or gamma rays, UVC radiation doesn't have enough energy to ionize atoms, meaning it doesn't directly damage DNA or create free radicals.
* Highly Absorbed: UVC is strongly absorbed by most materials, including air, water, and glass. This means it can't penetrate very far and has limited use for disinfecting surfaces that are not directly exposed to the radiation.
* Harmful to Humans: UVC radiation is harmful to human skin and eyes. Exposure can cause sunburn, eye damage, and even skin cancer.
Applications of UVC:
* Disinfection: UVC lamps are used to disinfect surfaces, water, and air.
* Medical Equipment Sterilization: UVC radiation is used to sterilize surgical instruments and other medical equipment.
* Food Processing: UVC is used to kill bacteria and mold in food products.
* Water Treatment: UVC is used to disinfect drinking water.
It's important to note that UVC radiation should only be used with appropriate safety precautions. Protective gear should be worn when operating UVC devices, and exposure to direct UVC radiation should be minimized.
