A sun tan is the skin’s
first indication of sun
damage.
Less than 20% of
Americans wear sunscreen
year-round.
Skin cancers occur three
times more commonly than
breast and lung cancers
combined.

UV Radiation Safety tips
Any
time the sun's ultraviolet (UV)
rays are able to reach the earth
there is a risk for excessive
sun exposure. The ultraviolet
(UV) portion of sunlight is an
invisible form of radiation that
can penetrate and change the
structure of skin cells.
Exposure to UV rays appears
to be the most important
environmental factor in the
development of skin cancer and
has also been associated with
various forms of eye damage,
such as cataracts.
There are three types of UV
rays: ultraviolet A (UVA),
ultraviolet B (UVB), and
ultraviolet C (UVC).
UVA is the most abundant
source of solar radiation at
the earth's surface, and
penetrates beyond the top layer
of human skin. Scientists now
believe that UVA radiation can
cause damage to connective
tissue and increase a person's
risk of developing skin cancer.
UVB is less abundant at
the earth's surface than UVA
because a significant portion of
UVB is absorbed by the ozone
layer. UVB does not penetrate as
deep into the skin as UVA does,
but, nonetheless, can also be
damaging and has been associated
with the development of skin
cancer.
UVC radiation is extremely
hazardous to skin, but it is
completely absorbed by the
stratospheric ozone layer and
does not reach the surface of
the earth.
