Study Upon Specific Absorption Rate Values for Different Generations of Mobile Phones by Using a SATIMO-COMOSAR Evaluation Dosimetry System

The problem of the human exposure to different types of electromagnetic field sources is a challenging one and should be considered an up to date issue, especially due to the actual trends and progress in mobile communications technology. The here presented paper proposed a study on the measured values of specific absorption rate (SAR) for three mobile phones, GSM-900 and GSM-1800 MHz bandwidths, using a SATIMOCOMOSAR system, provided by an accredited laboratory. A comparison of the SAR values determined by measurements with those from standards has been also done and the conclusions have been taken for different cases of exposure scenarios.

I. Introduction

As concerning the penetration of electromagnetic radiations in the human body for frequencies between 10 and 104 MHz, exposure for general public, limits for the specific absorption rate (SAR) have been imposed: 0.08 W / kg on average for the whole human body, respectively 2 W / kg for SAR located in the head or trunk area. These SAR values are averaged over a 6 minute exposure time and a corresponding volume of 10 g of tissue. [1–3].
