SELECTIVE RADIATION MEASUREMENT FOR SAFETY EVALUATION ON BASE STATIONS

Abstract

In this paper, general information about, unionized radiation, standards and measurement routines for wireless communication systems, electromagnetic fields and antenna structures are given. The safety of mobile phones has been evaluated in terms of specific absorption ratio (SAR). This SAR values have been defined discussing among international standard organizations. Electromagnetic Compatibility (EMC) measurements are made with a compact spectrum analyzer device, measures 400 MHz- 6 GHz bandwidth, and a triaxial antenna. Electromagnetic fields and power flux density values are measured, and compared with ICNIRP standard curve for safety values. These values are observed and separated for two base stations at the same point. Measured electric field and power density values are plotted by distance from base station tower, and compared with theoretical results. Safety distance is defined and calculated
