Abstract

Overview

This letter to the editor from the journal Bioelectromagnetics explores the Radiofrequency (RF) exposure levels in 102 primary schools in Amsterdam. The findings indicate a significant presence of RF from various sources in educational environments.

Findings

• GSM Base Stations: These contribute 38.0% to the total average RF power density. They are the primary source of radiofrequency exposure.
• DECT Cordless Phones: Account for 27.3% of the exposure.
• GSM Mobile Devices: Contribute 11.1% to the RF exposure.
• WiFi at Schools: Represents 4.5% of the total RF power density. Note that the assessments were performed post-school hours, which may underestimate WiFi's contribution during active usage hours.

Conclusion

The report emphasizes the prevalence of RF exposure levels in schools, potentially posing health risks to children. The greatest contributions are from GSM base stations and DECT phones, with non-negligible amounts from mobile devices and WiFi.
