What are the different types of ultraviolet radiation?
The sun puts out three different types of ultraviolet radiation (UV): UVC, UVB, and UVA. According to NASA, UVC rays are the most harmful, but fortunately are completely absorbed by the ozone layer and normal oxygen. UVB rays–often called the “burning rays”–are mostly absorbed by the ozone layer, but a portion of UVB rays do get through. UVA is NOT absorbed by the ozone.
