  BROAD-SPECTRUM ULTRAVIOLET (UV) RADIATION, UVA, UVB, UVC,
  SOLAR RADIATION, AND EXPOSURE TO SUNLAMPS AND SUNBEDS
  INTRODUCTION
  Solar radiation and exposure to sunbeds and sunlamps were first listed in the
  Ninth Edition of the Report on Carcinogens as known to be human carcinogens.  Broad-
  spectrum ultraviolet radiation (UVR) and its components ultraviolet A radiation (UVA),
  ultraviolet B radiation (UVB), and ultraviolet C radiation (UVC) were reviewed for
  listing in the Tenth Edition of the Report on Carcinogens.  Because exposure to solar
  radiation and to sunbeds and sunlamps involves exposure to broad-spectrum radiation,
  these listings have been combined into one profile.  Much of the evidence for listing the
  various exposures applies to more than one type of UVR.  Evidence for the
  carcinogenicity of broad-spectrum UVR comes from studies on solar radiation and
  exposure to sunbeds and sunlamps.  Similarly, animal and mechanistic studies to evalua
