Analysis of Exposure to Electromagnetic Fields Due to Multiple Sources in a Classroom Environment

This paper presents an analysis of the electromagnetic fields (EMF) exposure to multiple sources in a classroom environment. The research is motivated by the increasing use of electronic devices in educational environments and the need to estimate this. The methodology used involves simulating a classroom with students using laptops, which are considered as the main sources of electromagnetic radiation. The 1g and 10 g peak spacial Specific Absorption Rate (psSAR) are calculated for different parts of the human body, including the head, back, and hands. The results indicate that the psSAR is higher in the back, followed by the head and hands. When the free distance between desks is 250 mm, two-fold at the hands to forty-five-fold at the back greater psSAR are obtained when comparing to just one student with his laptop.
