要約(英語): There are few published papers on whole-body average specific absorption rates (WBA-SARs) in humans for multiple radio-frequency (RF) simultaneous exposures. In this paper, to evaluate human safety of radio waves in real environments, we calculated WBA-SARs in pregnant woman and 3-years child models for multiple RF exposure, using measured results on electric field intensities from multiple base station antennas installed for cellular phones with four different RF waves in an underground shopping area and with five RF waves in the neighborhood of an elementary school, respectively. These data were reported officially in 2008 by the Ministry of Internal Affairs and Communications. Statistical analyses show that the sum of squared ratio of the measured electric field to the corresponding Japanese guideline for the general public is smaller than one-hundredth and one-thousand at most in the underground shopping and elementary school areas, respectively. As a result, we found that WBA-SARs in the pregnant woman and 3-years child models calculated at each of frequencies for base station antennas in the both areas are significantly low compared to the ICNIRP basic restriction (0.08 W/kg) for the general public, and that the sum of the WBA-SARs never exceed one-hundredth of 0.08 W/kg for multiple RF simultaneous exposures.
