Solar ultraviolet (UV) radiation [?]

Rough clear sky estimates. Wavelengths: UVA λ=360 nm, UVB λ=300 nm. Source: CICARMA, Emanuela, et al. Sun and sun beds: inducers of vitamin D and skin cancer. Anticancer research, 2009, 29.9: 3495-3500.

  • Both UVA and UVB cause skin damage (sunburn, premature aging, skin cancer).
  • UVB is responsible for delayed tanning and burning.
  • UVA is responsible for the immediate tanning effect.
  • Exposure to UVB radiation helps the skin produce vitamin D (D3).
