Ultraviolet (UV) light is
electromagnetic radiation with a wavelength shorter
than that of visible light. It is produced by
the sun and can be created artificially using
florescent lamps.
The UV rays from the sun include UVA and UVB,
both of which are present in our atmosphere. The
Ozone Layer, which covers the earth, helps regulate
the levels of ultraviolet radiation, but unfortunately,
increasing amounts of environmental toxins in
our atmosphere have caused a steady depletion
in this protective layer. As a result, increasing
amounts of cancer causing UV radiation is reaching
the Earth’s surface.
