Ultraviolet Radiation

Ultraviolet Radiation is naturally found in sunlight.

We cannot see or feel it but our skin responds to it by turning darker. <-- This happens in an attempt to reduce the amount of ultraviolet radiation that reaches deeper skin tissues.

Darker skins absorb more ultraviolet light, so less ultraviolet radiation reaches the deeper tissues.

THIS IS IMPORTANT BECAUSE... ultraviolet radiation can cause normal cells to become cancerous.

Ultraviolet radiation is used in:

  • sunbeds
  • security pens
  • flurescent light (coatings inside the tube or bulb absorb the ultraviolet light and re-mit it as visible light)
