In the present paper, the values of SAR in case of human exposure to mobile phone was determined via different methods. For SAR values determination were studied and compared two case of exposure, one in near field and other in far field. Also it was determined the SAR in human head depen...
Human exposure to electromagnetic fields emitted by mobile phones is characterised by the Specific Absorption Rate (SAR). This value corresponds to the RF power absorbed by unitary mass of the equivalent tissue. It represents the basic restriction used to define limit of human exposure to RF ...
This paper gives a first comparison of specific absorption rate (SAR) induced in a child-sized (CS) head and an adult head using a dual-band mobile phone. In the second study, the visible human head is considered and comparison of SAR induced in a CS or child-like (CL) head and an...
* In the United States, the SAR limit for mobile phones used by the public is 1.6 watts/kilogram (W/kg) averaged over one gram of tissue. The standard incorporates a margin of safety to give additional protection for the public and to account for any variations in measurements. 3 ...
the actual SAR level of the device while operating can be well below the maximum value. This is because GSM phones are designed to operate at multiple power levels so as to use only the power required to reach the network. In general, the closer you are to a wireless base station antenna...
SAR exposure limits differ between the countries/regions, the following table provides mobile phones’ SAR limits of various countries. Country Certification SAR Limit United States FCC 1.6 W/Kg Canada ISED 1.6 W/Kg European Union CE 2.0 W/Kg The FCC (US) has set some guidelines to restrict...
