摘要
New child voxel models that are adjusted to the International Commission on Radiological Protection (ICRP)'s reference values (1-, 5- and 10-yr-old children) have been developed. The whole-body averaged specific absorption ratios (WBA-SARs) of these child voxel models were calculated for the whole-body exposure conditions with the E-polarization and H-polarization plane wave incidence from 10 MHz to 6 GHz. The WBA-SARs are 40% to 60% higher for the child voxel models than for adult voxel models adjusted to the ICRP's reference values (NORMAN and NAOMI). The WBA-SARs of the child voxel models exceed the basic restriction by at most 20% or 0.08 W/kg for the general environment when the incident power density is set to the reference level at each frequency of the ICNIRP's RF safety guidelines.
