Summary The aim of this work is to examine the differences in power absorption in the brain of adults and children exposed to the
radiation of mobile phone terminals at 1710 MHz. To this end, simulations using the Finite-Difference Time-Domain (FDTD) method
have been carried out to study the interaction between heterogeneous anatomically correct models of the human head and a linear
or helical monopole mounted on the top of a metal box representing a realistic mobile communication terminal. The study includes
computations of specific absorption rates (SARs) inside the human head and the total power absorbed by the head. Emphasis
is placed on the comparative assessment of power absorption characteristics in heads of adults and children as well as on
the effect of various parameters such as the age-related changes in dielectric properties and the usage distance between the
user's head and the mobile terminal. 相似文献
