Specific exposure levels were not quantified in this study. The study examined exposure from: 900, 1800 and 2450 MHz

Study Details

The objective of this study was to investigate possible variation in specific absorption rate (SAR) in the head region of children and adults by applying the finite-difference time-domain (FDTD) method and using anatomically correct child and adult head models.

In the calculations, the conductivity and permittivity of all tissues were increased from 5 to 20% b...

The analyses suggest that increasing the value of dielectric parameters does not necessarily mean th...
