Differences in RF Energy Absorption in the Heads of Adults and Children

Andreas Christ and Niels Kuster, in Bioelectromagnetics, Volume 26, Issue S7, pp. S31–S44, December 2005

This paper provides a comprehensive review of the current state of knowledge about the parameters and mechanisms affecting the exposure of the mobile phone user with special focus on the exposure of children. Discussed are the absorption mechanism, tissue parameters, the effect of the pinna, and the uncertainties associated with head models based on spheroids, scaled adult heads, and magnetic resonance imaging (MRI) data of children. The conclusions of the review do not support the assumption that the energy exposure increases due to smaller heads, but identifies open issues regarding the dielectric tissue parameters and the thickness of the pinna.
