Melanin helps the body filter out UV radiation, but it also can be harmful.
Cataracts attributable to UV radiation are estimated to have caused the loss of about 500 000 DALY's in 2000.
The mechanisms are unclear, but it may be that skin is more susceptible to the harmful effects of UV radiation during childhood.
The results showed that UV radiation mainly led to crystal destruction and molecular degradation on the surface and recrystallization on the interior part of the sample.
UV radiation-induced cataract model in rats
There is also evidence that UV radiation reduces the effectiveness of the immune system.
Several studies have demonstrated that human skin can be protected against UV radiation by using plant-derived antioxidants.
External environmental causes of cancer are factors in the environment that increase risk of cancer such as air pollution, UV radiation and indoor radon.
The sand bags should either be wrapped in black garbage bags or the bag material should be the kind that is resistant to breakdown from UV radiation from the sun.
As the ozone layer is depleted, more UV radiation reaches the Earth's surface.
