| Abstract | ||
| The Ultra Violet ray (UV) less than 0.4 micron is apart of the electromagnetic spectrum that reach the earth from the sun light, this ray has dangerous effect on life in general and on humans in particular causing skin cancer if the UV index is more than the range of 6 to 7 degree.This research may measure the UV Index for first time and will find the relation between the temperature and the strength of UV reach Baghdad by dailymeasurement for period of 15 months, to define the possible changes of the ray on life. The index we found about 6.88 that mean in high level and the temperatures has very strong effect at the UV ray especially in summer at mid day.In the present work first a brief review of the absorption spectra is presented. Practically the interest was to daily measure the UV index in Baghdad for the first time and to find the relation between the temperature and the strength of reached UV for a period of 15 months. The index was found to be 6.88, this means it is within the high range for Baghdad and the temperature has a very strong effect on the UV ray especially in summer at mid day. | ||
