Development of thermal model in a child and its application to dosimetry due to RF whole-body exposures.
In this study, we developed a thermal model for children to simulate body-core temperature elevation. In comparison of measured and simulated temperatures, the thermoregulation in a child was reasonable to consider the same as in the adult. Based on this finding, we calculated the body-core temperature elevation in the 3-year child and adult for plane wave exposure at the basic restriction in the international safety guidelines. The body-core temperature elevation in the 3-year child model was 0.03 degrees C at the whole-body averaged specific absorption rate of 0.08 W/kg, which was 35% smaller than in the adult female. This difference is attributed to the ratio of the body surface area to the mass.
