SAR estimations in a child due to RF exposures from several laptops in a classroom environment

This research provides a detailed examination of the exposure to electromagnetic fields (EMF) in a classroom environment. The study is driven by the escalating integration of electronic devices in educational settings and the subsequent necessity to estimate the implications of this on the overall exposure. The employed methodology simulates a classroom filled with several 7-year-old girls realistic models, each using a laptop, which are the primary sources of electromagnetic radiation. The 1g and 10g peak spatial Specific Absorption Rate (psSAR) are calculated for various parts of the child model, including the head, back, and hands. It is observed that, when several laptops are used, the psSAR can be substantially increased (e.g. up to 40-fold). One objective of this study is to enhance the understanding of potential EMF exposure effects in relation to age and to provide guidelines for the design of safer classrooms in the context of widespread laptop usage.
