Abstract
Cellular mobile communication technology has grown exponentially in the last decade resulting in large number of base stations in areas at which people are living or working. All over the world, the electromagnetic pollution produced from cellular base stations erected in residential areas and its effect on the environment and human body is a problem that has been concerning the society for many years. This paper, introduces the effects of electromagnetic energy emitted cellular base stations on the biological systems of the human body. The induced electromagnetic fields (EMF), and specific absorption rate (SAR) were calculated in close proximity to cellular mobile base stations. The calculated values of SAR were compared with the most commonly used international limits. The results show that the electromagnetic radiation (EMR) exposure levels at a distance of several meters from the base station towers can cause hazardous effects to the public

Base station antennas transmit in the frequency range of 935 to 960 MHz (GSM-900), 1810 to 1880 MHz (GSM-1800). 3G cellular system has been adopted in many countries, in which base station antennas transmit in the frequency range of 2110-2170 MHz [1] [2]
Summary
The Global System for Mobile communications (GSM) are second-generation (2G) systems were adopted in many countries all over the world. Base station antennas transmit in the frequency range of 935 to 960 MHz (GSM-900), 1810 to 1880 MHz (GSM-1800). 3G cellular system has been adopted in many countries, in which base station antennas transmit in the frequency range of 2110-2170 MHz [1] [2]. Base station antennas are usually mounted on the roofs of buildings or on freestanding masts, and down-tilted, so that the signals are directed towards ground level. Cellular mobile communication system operates via base stations, and each base station covers a limited region(cell) [3]. Many base stations were erected in areas of high population density
