Title: أثار الاشعة الراديوية المنبعثة من المحطات القاعدية لنظم الهاتف السيار
Author: علي حمد عباس, محمد
Abstract: In this report the hazards resulting from exposure to radiation at the operating frequencies of mobile telephone systems are discuss ed. It has been concluded that the probable effect is the heating of the tissues o f the human body in case of exposure to a power density that exceeds the internationally agreed upon limit, and this may lead to cataracts and deep and superficial skin bur ns or wounds. The internationally agreed upon safe limit is 0.57 mW/sq. cm in case of frequencies around 900MHz and 1.2 mW/sq. cm in case of frequencies around 2000MHz . And, if when installing mobile telephone systems base station antennas the necessa ry procedures are followed, the above mentioned hazards will not prevail. However, this does not rule out the existence of other hazards that are now unseen.
