What is the primary benefit of using ultraviolet radiation for sterilization?

1. It is inexpensive

2. It is quick and effective

3. It requires no special equipment

4. It is environmentally safe

The correct answer is: It is quick and effective

The primary benefit of using ultraviolet (UV) radiation for sterilization is that it is both quick and effective. UV radiation works by disrupting the DNA of microorganisms, including bacteria, viruses, and fungi, which prevents them from reproducing and effectively eliminates them from surfaces, air, or water. This process typically occurs within seconds to minutes, making it an efficient method for achieving sterilization in a relatively short period of time. In contrast, while cost considerations, the absence of need for extensive equipment, and environmental safety may present advantages in specific contexts, they do not encompass the defining attributes of UV sterilization. The speed and efficacy with which UV radiation can neutralize pathogens make it a popular choice in environments where rapid disinfection is critical, such as in medical and nail care settings.
