Final Report on Carcinogens Background Document for Broad-Spectrum Ultraviolet (UV) Radiation and UVA, and UVB, and UVC.

摘要

Broad-spectrum ultraviolet radiation (UVR) is known to be a human carcinogen based on sufficient evidence of carcinogenicity from studies in humans. Epidemiology studies clearly demonstrate that exposure to broad spectrum UVR increases both melanocytic and non-melanocytic skin cancer. Studies of humans exposed to solar radiation, artificial devices emitting broad-spectrum UVR, and devices emitting predominantly ultraviolet A radiation (UVA) or ultraviolet B radiation (UVB) all contribute to this conclusion.
