SAFETY MEASUREMENT OF ELECTROMAGNETIC FIELD RADIATION FROM MOBILE STATIONS AT A NAJRAN CITY IN KSA

Abstract

The recent years shows increasing mobile users every day. In order to supply the demand suppliers of different companies’ install many base stations almost everywhere. This paper focuses on reporting measurement of the power density around mobile base stations to locate the Maximum Peak Point (MPP). The safety measurement was performed at different distances and directions from 20 selective base stations located in Najran city Saudi Arabia using Radio Frequency (RF) Electromagnetic Field Strength Meter Model 480846. The measured power density ranged between 195.5 μW/m2 and 12540 μW/m2 at 5 to 100 m from the base station. The result of the paper shows that the maximum power density of 12540 μW/m2 is by far less than the ICNIRP values of 4.5 W/m2 and 9.0 W/m2. The results show that power density levels at all surveyed sites are far below the National Guidelines for public exposure to RF and that the MPPs are found within the distance range suggested in the Commutation and Information Technology Commission (CITC) in Saudi Arabia.
