Abstract
In this paper, we compared the spatial peak SAR values measured with and without holding the hand-held phones to check the present recommended spatial peak SAR. To better understand the analysis of the SAR effect values, SAR is measured with hand phantoms, made and recommended for the use of Bar-type and Folder-type hand-held phones. The measured results have shown that use of the hand considerably reduces the spatial peak SAR value in a head phantom. We compared the spatial peak SAR values measured with and without accessories. To better understand the analysis of the effects of SAR values with accessories, SAR is measured with accessories composed of three kinds of earrings and glasses. The measured results proved in study that the spatial peak SAR value in a head phantom is not affected by the earrings but by the glasses. The glasses considerably increases the spatial peak SAR value in a head phantom while using Bar-type phones, although the effects are modest with Folder-type phones.
