Abstract (in Japanese) (See Japanese page) 
(in English) In international guidelines for protection against radiofrequency electromagnetic exposure, the whole-body averaged SAR (Specific Absorption Rate) is adopted as an evaluation metric for protection against whole-body exposure. In the GHz frequency range, particularly above 6 GHz, electromagnetic energy is primarily absorbed within the skin layer, and thus the temperature elevation of the human body under whole-body exposure is likely to be influenced by heat transfer due to blood perfusion in skin tissues. In conventional temperature-elevation analyses, however, skin blood perfusion has been assumed to be constant within each tissue, and the site-specific variation known to exist in the actual human body has not been adequately considered. In this study, we measured the skin blood perfusion at 18 sites over the whole body in 14 adult male subjects using a laser Doppler flowmeter, introduced the resulting site-specific variation into a numerical human model, and quantitatively evaluated its influence on skin temperature elevation under whole-body exposure. For 28 GHz plane-wave exposure, with the whole-body averaged SAR normalized to 0.4 W/kg, the skin temperature elevation in the abdomen and thigh, where the blood perfusion is smaller than the representative value, was approximately 25% higher than that obtained with the conventional model assuming constant blood perfusion, demonstrating that the site-specific dependence of skin blood perfusion has a non-negligible influence on temperature elevation assessment.
