UVB is a term used in medical circles to describe ultraviolet light with short wavelengths that penetrate the skin and cause damage. There are several synonyms for this term, including "B-band radiation," which refers to the part of the ultraviolet spectrum that ranges from 280 to 320 nanometers. Another synonym is "erythemal UV," which pertains to the specific range of UVB light that causes redness and skin damage.
