Abstract:

Based on the anatomically realistic model of human body , an electromagnetic model of human body is established , which includes the human head and hand. In both the vertical and the tilted operation ways , the effect of wearing metal-frame spectacles on the radiative dosage absorbed by human body , which derives from a handset antenna , is analyzed via numerical simulation. The results show that wearing metal-frame spectacles leads to an obvious increase of specific absorption rate (SRA) to the human body , especially to the eyes where the SRA value may double. However , all the calculated values of SRA are less than the one accepted by the intemational non-ionizing radiation protection standard.

Key words: mobile radiation, metal-frame spectacles, specific absorption rat
