As sunshine passes through the atmosphere, all UV-C (wavelength 100-280) and
approx. 90% of the UV-B radiation is absorbed by ozone, water vapour, oxygen
and carbon dioxide.
UV-A radiation (wavelength 315-400 nm) is less affected by the atmosphere,
therefore
the UV radiation reaching the Earth's surface is largely composed of UV-A with
a small UV-B (wavelength 280-315 nm) component.
The numbers of affected people shocked us in the recent years:
1) Photoaging: photoaging affects at least 35% of the American population alone
and
even more in the other countries where the sunshine is more intense.
Exposure to ultraviolet light, UVA or UVB, from sunshine accounts for 90% of the
symptoms of the premature skin aging. Most of the photoaging effects occur by
age 20
2) Skin cancer: Melanoma is the most dangerous of all skin cancers. This year
7,800
Americans will die of it - many of them young and in the prime life. About one-
fourth
of all the cases occur in persons under the age of 40, with women making
up the majority. Melanoma is now the most frequent cancer in women in the U.S.,
aged 25-29, and is the second only to breast cancer for those in the 30-34 age
group
