Sunlight contains many rays invisible to
human eyes. Of such rays, UV has its wavelength at 100-400nm, taking
6.1% of sunray.
In accordance with the idea of WHO,
radiation is the key cause to the skin cancer and cataract in various
places in the works. Shown as the related data, 800 out of 100,000
Australians will suffer the skin cancer per year; 250 out of 100,000
Americans will suffer the skin cancer.
In USA and Canada where the sunbath is
popular, each year will see one million of new patients of skin cancer.
For UV will have a long-term impact on
human body, people shall pay attention to prevent the UV harm from the
childhood whereas kids are prone to sunburn, so that the particular
attention shall be given to children.
Presently, many national and regional
meteorlolgical observatories, astronomical observatories and other
organizations in the world will release the indices, reminding people to
prevent the UV. The WHO has established the international standard of UV
indices so as to guide all nations to prevent the UV. |
With the gradual consumption of ozone layer of
the earth (4%~6% consumed each year), and the cavity is being enlarged
and then the radiant quantity of UV is being increased. Now the human
life style is changed, and outdoor activities are more. People used to
apply the cosmetics to protect the exposed skin, but now they will wear
the clothes to prevent the harm from the UV to the covered parts, so
that the anti-sunburn measures are carried out perfectly. For those
parts not exposed directly to sunshine, such measures shall be still be
taken. The anti-sunburn clothes and ornaments are useful and applicable,
and such objects are playing an important role for such purpose.
The developed countries provide that the school uniforms for middle and
primary school students shall be made with the UV-proof fabrics.
