The extraordinary usage of cell phones results in public concerns regarding the potential health effects resulting
due to exposure to the microwave radiation produced during smartphone usage. The thermal effect due to exposure to
microwaves radiations is the most known biological effect. Studying the heating characteristics on human head models can
be used to investigate the influence of these waves on human biological medium as it allows calculating temperature
elevation. The specific absorption rate (SAR) is the physical quantity most often used to investigate the biological effects
produced due to the electromagnetic energy absorbed by the human head-sensitive tissues. This paper focuses attention on
human head tissues to estimate the rate of the induced specific absorption rate (SAR) distribution and the temperature
elevation through a numerical approach. A model of a human head with four layers was built to predict the thermal
distribution inside the human head tissues exposed to phone RF radiations at different frequencies with the help of a bioheat
equation. The simulation results show that the temperature elevation in the skin and brain tissues at all frequencies
never exceeds 0.1 C, and the generated SAR is well below the safety limits for the adverse thermal effects.
