Abstract

Overview

This study represents the first of its kind in Mexico using personal exposimeters to measure exposure to Radiofrequency Electromagnetic Fields (RF-EMF) from Wi-Fi frequencies.

Findings

Research was conducted in various microenvironments such as homes, workplaces, outdoor areas, schools, during travel, and in shopping areas with 63 volunteers. The study measured the following:

  • Minimum exposure levels recorded were 146.5 μW/m2 and 116.8 μW/m2 for Wi-Fi 2G and 5G bands respectively, during travel and at home.
  • Maximum exposure levels recorded were 499.7 μW/m2 and 264.9 μW/m2 at the workplace for Wi-Fi 2G and 5G bands.
  • Daytime measurements showed higher exposure levels compared to nighttime.

None of the measured values exceeded the international limits set by ICNIRP despite substantial variations across different settings and times of the day.

Conclusion

The population of Tamazunchale shows a significant concern over exposure to RF-EMF compared to several European cities. This concern shifts once the community receives information regarding actual exposure levels relative to health standards.
