  • UVB radiation is slightly longer than UVC (280-315nm), and approximately 90% of UVB is absorbed by the atmosphere; therefore, the radiation reaches the Earth's surface contains less than 2% UVB.
  • UVA has the longest wavelength (315-400nm), and over 98% of the radiation that reaches the Earth's surface is UVA because it is less affected by the atmosphere.
