To avoid potentially adverse health effects of electromagnetic fields (EMF), the International Commission on Non-Ionizing Radiation Protection (ICNIRP) has defined EMF reference levels. Restrictions on induced whole-body averaged specific absorption rate (SARwb) are provided to keep the whole-body temperature increase under 1◦C. Additional restrictions on the peak 10 g spatial-averaged SAR (SAR10g) are provided to prevent excessive localized tissue heating. In this study the localized peak temperature increase in children upon exposure at the reference levels has been assessed using simulations of multiple anatomical models. A peak temperature increase as high as 1◦C can occur for worst-case scenarios at the ICNIRP reference levels. It is recommended to use peak temperature increase as a better metric to prevent excessive localized tissue heating instead of localized peak SAR and to consider the exposure duration.
The scientific and technical impact of the study can be summarized as:
