✦ Synopsis

Specific absorption rate (SAR) was measured in models of the human head exposed to hand-held portable radios ("transceivers") transmitting at frequencies in the 800-MHz band. An isotropic implantable electric-field probe was used to measure internal fields induced in the head models, and SARs were determined by calculation. As well as determining representative values and distributions far SARs under various canditions, it was shown that antenna type and orientation with respect to the head are important factors affecting energy absorption.

Electric fields (E-fields) induced within a phantom head from exposure to three different advanced mobile phone system (AMPS) hand-held telephones were measured using an implantable E-field probe. Measurements were taken in the eye nearest the phone and along a lateral scan through the brain from it
