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.

人体暴露于移动通信射频电磁场下的比吸收率评估
EMC是与无线电通信相关的许多项目面临的长期挑战。在这个大框架内,人类暴露问题应始终考虑。因此,了解电磁场辐射对人体生物组织的短期和长期影响是值得研究的。本文研究了利用特定仪器(配备HyperLOG 60100天线的Spectran HF-60105 V4频谱分析仪)对人体三维模型在某些区域(室内和室外)暴露于移动通信产生的电磁场下的比吸收率(SAR)估算。利用CST MW Studio®软件模拟确定了SAR值,并将这些值与ICNIRP(1998)限制限值和欧洲指令2004/40/CE标准所规定的SAR限值进行了比较,该标准也于2006年8月30日在罗马尼亚被HG号1136采用。此外,在处理同时暴露于不同频率场时,应考虑RSAR。
