Ionizing-radiation-resistant organisms (IRRO) were defined as organisms … WebUV light is highly effective at killing germs. The three main types of UV rays are UVA, UVB, and UVC. Because UVC rays have the shortest wavelength, and therefore highest energy, they are capable of killing bacteria and viruses, also called pathogens. UVC light has a wavelength of between 200 and 400 nanometers (nm).
