Abstract

Overview

This study investigates the exposure of students and faculty to Radiofrequency Electromagnetic Fields (RF-EMF), specifically from 2.4 GHz and 5.85 GHz Wi-Fi, at the Faculty of Computer Science Engineering at the University of Castilla-La Mancha in Spain.

Findings

  • Continuous monitoring over three years (2017 to 2019) and specific measurements in 2022 in classrooms and an office.
  • The minimum exposure observed was 0.0900 μW/m² in 2.4 GHz Wi-Fi in 2019, and the maximum was 211 μW/m² in 5.85 GHz Wi-Fi in 2017.
  • A significant variance in exposure levels is noted depending on the location and whether students were present, with a peak of 278 μW/m² in a classroom with students.

Conclusion

The study found that RF-EMF levels varied but did not exceed ICNIRP guidelines (10 W/m² for the general public). These findings are crucial as they stress the potential health risks associated with RF-EMF exposure, which, while compliant with guidelines, calls for continued scrutiny and further research.
