According to the increasing of mobile phone radiation exposure. Many research has been evaluated the specific absorption rate which is the power dissipation rate normalized by material density in human life tissue exposure to the radiation. Therefore, in this work, the electric field, magnetic field and specific absorption rate generated inside a three human life tissue of head model are studied. The electromagnetic radiation can be measured in terms of specific absorption rate. The human head exposed to global system for mobile communication frequency bands of 900MHz. The radiation absorption analyzed through simulations by using three dimension finite difference time Domain method and computer software program. The penetration of the fields and power density were computed inside the model of human head. Results show that electromagnetic fields penetrate the life tissues and attenuate fast to reach zero at the brain layer, the peak is smaller than because the electric field strike the bone tissue. The absorbent power and specific absorption rate show maximum at the skin layer. Preliminary results show good agreement with previous published using numerical and software technique. Also the results suggest that three layer human model and simulation can help to understand the specific distribution of mobile phone electromagnetic fields inside the human head.
