What Are The Three Types Of UV Radiation? UV radiation is classified into three primary types: ultraviolet A (UVA), ultraviolet B (UVB), and ultraviolet C (UVC). These groups are based on the measure of their wavelength, which is measured in nanometers (nm= 0.000000001 meters or 1×10-9 meters). What are the 3 types of UV radiation

What Is The Most Germicidal Wavelength Of UV Light? The entire UV spectrum can kill or inactivate many microorganisms, but UVC energy provides the most germicidal effect, with 265 nm being the optimum wavelength. Which wavelength of UV is the most hazardous? The skin and eyes are most sensitive to damage by UV at 265–275
