| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Whole-body averaged specific absorption rates (WBA-SARs) is being used in various countries for radio-wave exposure. However, the safety limits are based on the behavioral destruction of healthy adult animals for radio frequency exposure, while these are not being derived from experimental results for young and pregnant animals. For this reason, we think that absorption properties in children and pregnant women for electromagnetic wave exposure should further be investigated. In this study, we calculated the WBA-SARs in 3-years, 5-years, 7-years and 22-years anatomical human models for vertically polarized far field exposure, and statistically analyzed their voxel SARs in the frequency range from 50MHz to 2GHz. As a result, we found that in comparison with the WBA-SARs, 50-percentile voxel SARs (median) in child models and 22-years model are smaller by 24-67 % (40 % at frequencies over 400 MHz) and by 13-62 % (50 % at frequencies over 400 MHz), respectively. | |
