Abstract

Overview

The rapid deployment of the 5G network prompts significant concerns regarding its potential health impacts, especially related to radiofrequency (RF) fields. Prior studies highlighted effects primarily from heating, but recent observations show effects on neuronal activity without heating.

Methods

• Neuronal cultures from embryonic cortices were monitored using multi-electrode arrays.
• Three specific absorption rates (SAR) were tested: 1, 3, and 28 W/kg, simulating environmental and above-standard exposure levels.

Findings

The study reveals that while low SAR exposure (1 and 3 W/kg) near guideline limits does not significantly influence neuronal activity, higher exposures (28 W/kg) clearly reduce the bursting and overall firing rates of neurons.

Conclusion

This research supports the hypothesis that high SAR levels related to 5G RF exposure can inhibit neuronal activity. It suggests a need for ongoing research into non-thermal effects of RF exposure and their mechanisms.
