| Abstract(in English) | In this paper, temperature-rises in fhe human head for portable telephones were computed with an anatomically based head model. The specific absorption rate (SAR) in the human head was determined using the finite-difference time-domain (FDTD) method, while a bioheat equation, which takes into account various heat exchange mechanisms such as heat conduction, blood flow and electromagnetic (EM) heating, was numerically solved also using the FDTD method. Computed results show that, for an uncontrolled environment, application of the ANSI/IEEE safety guidelines restricting the one-gram-averaged peak SAR to 1.6W/kg results in maximum temperature-rises in the brain of 0.05℃ at 900MHz and 0.06℃ at 1.5GHz, and application of the ICNIRP/Japan safety guidelines restricting the ten-gram-averaged peak SAR to 2W/kg results in maximum temperature-rises in the brain of 0.10℃ at 900MHz and 0.11℃ at 1.5GHz. |
