Investigation of the Ultraviolet rays(UV-Ray) in MAKHWAH, Kingdom Saudi Arabia

This work studies the investigation of the UV-rays in Makhwah, Kingdom Saudi Arabia, during the time 1996-2002. Ozone layer in the stratosphere serve as shield harmful UV rays His presence in this layer is useful for the protection of life and without it perhaps being human to several diseases such as skin cancer and cataracts and weakened immune systems as a result of breaking the DNA (DNA) by UV and less plant production plant as a result of exposure to different diseases.The ozone gas is considered among the endothermic gas absorbs infrared reflected from the surface of the earth and destined to outer space and thus contribute to the heating of the earth. The proportion of ozone harmful to beneficial ratio of ozone in the atmosphere depends on the balance between consuming processes (destructive)-depleting substances and those operations producing any imbalance in this will lead to serious consequences for life on Earth.That God flesh of the dangers of exposure to UV ozone layer man must reduce the use of psychoactive substances on ozone depletion.Man must good knowledge of the index of exposure to ultraviolet rays and how to protect himself from the dangers and lack of exposure to direct sunlight at least in times of 10 am to 04 Pm in the afternoon.The amount of exposure to ultraviolet rays in various cloud cover is Maximum values in clear sky and Minimum values in overcast cloud while in middle in case scattered and broken cloud.The summer and spring seasons susceptible to these harmful rays of UV-Capacity while less-Capacity Price impact of this unit in winter and autumn. In MAKHWAH Region which the correct height is 0.4 from sea level, the amount of exposure to ultraviolet rays in various cloud cover is Maximum values in clear sky which recorded 5 degree and Minimum values in overcast cloud which recorded 2 degree while in middle in case scattered and broken cloud.
