   Introduction (p 147)

   Solar UV radiation, especially UVB (wavelength, 290 to 320 μm), has been shown to be the most important factor leading to nonmelanoma skin cancer.

   Materials and Methods – Equipment (p 148)

   Approximately 80% of the lamp output was UVB (wavelength range, 290 to 320 μm), with less than 1% UVC (wavelength, less than 290 μm) and 4% UVA (wavelength range, 320 to 400 μm).
