Ozone Depletion, Increases Ultra-Violet Radiation

12 June 2012, Comments Comments Off on Ozone Depletion, Increases Ultra-Violet Radiation

Depletion of the ozone layer, allows more of the UVB rays to reach the earth. The higher levels of UVB rays will have an even greater negative impact on human health. Computational models predict that a 10% decrease in stratospheric ozone could cause an additional 300,000 non-melanomas and 4,500 melanomas skin cancers and between 1.6-1.75 million more cases of cataracts world wide every year .Uganda will be hit hard, being on the equatorial country, more than other developing countries.

What Is UV Index?

It describes the level of solar radiation at the earth surface. The values of the index range from zero upward. The higher the index value the greater the potential for damage to the skin eyes, and immune system, and less time for the harm to occur .UVA (315-400nm) UVB (208-315nm) UVC (100-280nm) Uganda has one of the highest UV Index .11+. This means that full sun protection should be used while in the sun and avoid the sun at midday .Full protection is: wearing a hat with a 7cm. brim ,sunglasses that wrap- around with the glossy finish long sleeves to protect the arms, and sunscreen Spf 15+ if available. Seek shade during midday hours. Arrange for children not to be out in the sun during the peck hours. Children under the age of six months should never be in the sun. Young children should be fully protected, and avoid the sun as much as possible.

Global Solar Ultra-Violet Index

This should be an important element of an intergraded and long term public health approach to sun protection. Sun protection programs are urgently needed to raise awareness of the health hazards of UV Radiation and to achieve changes in lifestyles. Effective education programs can strengthen national economies by reducing the financial burden to health care systems caused by skin cancers and cataract treatment)
