2. Sources of UV radiation

3. Some applications of ultraviolet

4. Sterilization: UV light is used for disinfection purposes in air, water, and surface sterilization. It can effectively kill or deactivate microorganisms, making it valuable in healthcare settings, laboratories, and water treatment plants. 2. Forensics: UV light is utilized in forensic investigations to detect and analyze biological fluids like blood, semen, or saliva. These substances often exhibit fluorescence under UV illumination, aiding in evidence collection and crime scene analysis .

5. 3. Phototherapy: Certain medical conditions, such as psoriasis, eczema, and vitiligo, can be treated using UV radiation. Controlled exposure to specific wavelengths of UV light can help alleviate symptoms and promote healing in these conditions. 4. UV Curing: UV curing is a process used in industries such as printing, electronics, and manufacturing. UV light is used to cure or harden materials like inks, adhesives, and coatings quickly and efficiently.

6. 5. Water Purification: UV radiation is employed in water treatment systems to disinfect drinking water and wastewater. It effectively eliminates bacteria, viruses, and parasites without the need for chemical additives. 6. Tanning and Sunbeds: While excessive UV exposure can be harmful, controlled exposure to UV light is used in tanning beds and sunbeds for cosmetic purposes to induce skin tanning.
