Abstract

Overview

This study aims to estimate the radiofrequency exposure levels around nursery and primary schools in the northwest part of Crete island, Greece, evaluating compliance with Greek legislation's exposure limits.

Key Findings

• 396 in situ frequency-selective and broadband measurements conducted around 69 schools, covering a frequency range of 27–3000 MHz.
• Most electric field strength measurements were below 1 V/m, indicating low exposure levels.
• Statistical analysis shows median exposure ratios significantly below the safety threshold of 1 in urban and suburban environments.

Conclusion

The study concludes that the vast majority of measurements comply with established Greek reference levels for RF exposure, highlighting a greater exposure in urban areas. Major sources include mobile communication and broadcasting frequencies.

Future Outlook

Future research plans include further EMF measurements around and inside school facilities, particularly with the upcoming introduction of 5G technology.
