A Characteristics of Temperature of the Local Tissue in the Human Body under Local Exposure of Electromagnetic Wave

전자파(電磁波)에 노출(露出)된 생체(生體)의 국소부위(局所部位)의 온도(溫度) 특성(特性)

There has been an increase in the public concern about possible health risks by electromagnetic exposure from mobile phones. Recently, increase in the use among young children of portable telephones public concern regarding potential health hazards due to a hot spot appearing inside the infant head, has been growing. Since the biological hazards due to RF exposure are caused mainly by a temperature-rise in tissue, the effect of localized SAR for portable telephones should also be related to the temperature-rise in the human head. In this paper, it was measured that in the actual use of portable telephone the temperature of the local tissue in the human-head change. As a result, it should be noted that the mean temperature of human-body and localized tissue is rising from beginning call. However the temperature variation of localized tissue is recovered rapidly as normal temperature, although the mean temperature of human-body rising continuously at ending call of portable telephone.
