Which type of radiation is known for having the most anti-bacterial effect?

The type of radiation recognized for its significant antibacterial effect is UV-C. This form of ultraviolet light has a wavelength range of 100 to 280 nanometers and is particularly effective at disrupting the DNA of microorganisms, leading to their inability to replicate and function properly. UV-C is utilized in various sterilization processes, including the disinfection of air, water, and surfaces, making it a crucial tool in infection control and hygiene practices.

In contrast, UV-A and UV-B, while part of the ultraviolet spectrum, have longer wavelengths and do not possess the same level of germicidal potency as UV-C. Infrared radiation, which primarily generates heat, is not effective in targeting bacteria or viruses, as it does not carry enough energy to disrupt biological structures. Therefore, UV-C stands out as the most effective in terms of antibacterial action.
