Abstract

Overview

The study investigates the exposure of children to radiofrequency (RF) electromagnetic fields from Wi-Fi in schools, addressing public concerns about potential adverse effects on children's health.

Findings

  • Measurements were taken in 23 Australian schools to assess typical and peak RF levels from Wi-Fi and other sources.
  • Both typical and peak RF levels were significantly lower than international safety guidelines.
  • Comparative analysis shows Wi-Fi exposure levels in classrooms and schoolyards were lower or comparable to other common RF sources such as radio and mobile phone base stations.
  • Duty cycle measurements indicated a median of 6.3% for 2.45 GHz and 2.4% for 5 GHz transmissions in the schools examined.
  • No significant difference in RF levels was found between empty classrooms and those with multiple users present.

Conclusion

Despite RF levels from Wi-Fi being much lower than safety guidelines, concerns persist about the adequacy of these guidelines, suggesting further investigation into the potential health impacts of RF exposure, especially from short-term intense pulses, might be necessary.
