RESEARCH TRIANGLE PARK, NC-The National Toxicology Program (NTP) plans to review the three wavelength groups of ultraviolet light-UVA, UVB, and UVC-for possible listing in the federal government’s Tenth Annual Report on Carcinogens. The three wavelengths occur in varying amounts in sunlight and in some forms of artificial light, such as that used in sun lamps and tanning beds.
