I have discovered in a leaflet based on a report for theGovernment, published in May 2000, by a group ofindependent experts that it is possible to mesure how much radio wave energy your body receives from each model of mobile phone and this is called the specific absorptionrate or SAR also I have found that the level of effectiveness of handsfree kit to reduce SAR is still uncertain.
Yo can find information about this research in this site:
