Specific Absorption Rate Evaluation in Case of Exposure of the Human Body to Radiofrequency Electromagnetic Field Generated by Mobile Communications

Abstract

EMC is a permanent challenge for many items associated with radio communications. Inside this large frame work, human exposure issue should be always considered. For that, it is worth of knowing the impact on the short and on the long term of electromagnetic field irradiation over biological tissues of human body. The present paper is a study over the estimation of specific absorption rate (SAR) on a developed 3D model of the human body in case of exposure to electromagnetic fields generated by mobile communications in some areas (indoor and outdoor) with specific instrumentation (Spectran HF-60105 V4 spectrum analyzer with HyperLOG 60100 antenna). The SAR values was determined by simulation using the CST MW Studio® software and the values were compared with limits values for SAR imposed by ICNIRP (1998) restriction limits and European Directive 2004/40/CE standards, adopted also in Romania by HG number 1136 from 30 august 2006. Additionally, the RSAR, while dealing with simultaneous exposure to different frequency fields should be considered.
