To protect yourself from UV radiation one of the easiest ways to
wear dark colored clothes or by wearing a special lotion with sunscreen that
can be applied to the hands, feet and neck because the clothes made of cotton
and polyester fairly effectively absorb UV radiation, therefore some kind of
lotion, so that UV radiation on the skin can be dependent on the value of
minimizing the SPF (Sun Protection Factor). SPF value is the comparison between
the dose of UV radiation received by the skin without a protective cotton /
lotion (ED) at a dose of UV radiation received by a protective skin with a
cotton / lotion (EDM), and expressed by the following equation: ED
Examples for lotion with an SPF value of 10, then the UV radiation
on the skin only 1 / 10 of UV radiation that comes and the 9 / 10 part is
absorbed by the lotion. The higher the SPF value for the fabric or lotion, the
smaller the UV radiation on the skin. This means more secure from the dangers
of UV radiation .
Remember every 1% thinning of the ozone layer by pollution
Clorotluoro Carbon (CFC) can increase the risk of skin cancer. BCC and SCC 3%
around 1.7%, needs to be further improved our concern for the earth that we
live is the socializing that begins CFC regressive free program from home.

of UV radiation for
the clothes of cotton and
polyester.
