title: Dosimetric techniques for the evaluation of the em power absorption induced by cellular phones.
abstract: International guidelines. ICNIRP, and proposed standards. IEEE-ANSI, define basic restrictions in terms of rate of power absorbed for mass unit (SAR) for localised exposure of electromagnetic fields such as in the near field region of cellular phones. Compliance tests of cellular phones consist in checking that emitted power from mobile telecommunication equipment (MTE) is below the reference levels and they are performed by assessing the absorbed power in specific head phantoms. The outcome of this work is the description of experimental procedures for evaluating SAR induced into the head by localised exposure. The set up instituted for compliance testing of MTE is described with the different components: dielectric simulators, electric field sensors. scanning system, remote control and data recording. Calibration procedures of E sensors and uncertainty evaluation of measures are presented. Finally the results of a comparison among a few European laboratories and of a test of some hand-set devices are shown.
