SAR evaluations for human bodies due to voice communications and data communications using a smartphone

Abstract

Recently, novel mobile phones such as a smartphone and a tablet computer have been spreading tremendously. We have more situations to be exposed to electromagnetic (EM) waves from mobile phones compared to the past. A lot of studies those evaluate the specific absorption rate (SAR) due to the conventional type of mobile phones. However, there are few studies that consider EM exposure from latest mobile phones. In this study, we evaluated the SAR in human bodies when they use smartphones for voice communications and data communications by computational simulation using a computational smartphone model and computational human models. As a result of this study, we confirmed that SAR when the smartphone was used for voice communications was higher than that when it was used for data communications. However, all SARs calculated in this study were lower than the value provided by International Commission on Non-Ionizing Radiation Protection (ICNIRP) guideline.
