N2 - The bio-heat equation including the thermoregulatory systems is solved for an anatomically based model of the human head with a resolution of 3 × 3 × 3 mm. In order to study the capability of thermal homeostasis of numerical head model, the time to reach the thermal steady-state under continuous RF exposure has been examined with the variation of power of a half-wave dipole antenna operating at 835 MHz. When the distance between the head and the antenna is 12 mm and the maximum transmitted power of the antenna is 600 mW, the maximum temperature increase in the head and in the brain is about 0.5°C and 0.24°C, relatively. It is found that the transmitted power increases (0.6, 1.2, 2.4, 4.8, 9.6 and 19.2 W), the rise in temperature reaches steady state after about 20 minutes for all cases.
