DOSIMETRIC ASSESSMENT AND BIOHEAT ANALYSIS OF ELECTROMAGNETIC EXPOSURE IN PEDIATRIC TISSUES

Abstract

Widespread deployment of Wi-Fi and cellular networks has significantly increased human-made electromagnetic (EM) pollution, disrupting natural background levels and spurring debate over the long-term health risks of continuous high-frequency exposure. Quantifying how radiofrequency radiation interacts with biological tissue is complex and frequency-dependent, making accurate assessment essential for public health and biomedical engineering. This research presents a numerical analysis of thermal effects across relevant communication bands using a child anatomical model, reflecting the heightened vulnerability of developing systems and higher tissue water content in children. Simulations carried out in FDTDLab using the finite-difference time-domain (FDTD) method modeled wave propagation and dielectric heating based on real-world field measurements. We quantified energy deposition using whole-body and localized (1g and 10g) Specific Absorption Rates (SAR), alongside thermal modeling for localized hotspots and systemic stress. Comparing these results with IEEE and ICNIRP guidelines offers crucial evidence regarding EM safety in pediatric populations
