Abstract

Category: Neuroscience Tags: 5G, electromagnetic fields, animal behavior, Wistar rats, central nervous system, experimental study, health risk DOI: 10.1134/s1062359024701875 URL: link.springer.com Overview A pilot experimental study was carried out to assess the effect of unmodulated and modulated electromagnetic fields of the 5G mobile communication standard on the central nervous system of animals. - Test subjects: Mature male Wistar rats - Exposure: Electromagnetic fields at 4.9 GHz, 250 μW/cm2, for 15 days, 2 hours/day - Conditions: Semi-anechoic shielded chamber, with identical conditions for control and irradiated groups Findings - The effect of the electromagnetic field was evaluated through behavioral analysis in the "open field" test before and after irradiation. - No clear differences were found between animal behavior under unmodulated and modulated 5G fields. - However, statistically significant changes in behavior were observed in both irradiated and control groups during the experiment. - These changes may be attributed to altered natural electromagnetic background from the use of a semi-anechoic shielded chamber. Conclusion 🔴 This study indicates that exposure to 5G electromagnetic fields may influence animal behavior and central nervous system function, though interpretation is complicated by changes in environmental electromagnetic background. Any link to changes in health or biological function—especially with long-term exposure or changes in electromagnetic environments—should be considered significant and warrants further investigation to ensure EMF safety.

Main findings

In this pilot study, no clear differences in behavior were observed between rats exposed to unmodulated versus modulated 5G electromagnetic fields. Statistically significant behavioral changes occurred over time in both irradiated and control groups, which the authors suggest may relate to changes in the natural electromagnetic background in the semi-anechoic shielded chamber.

Outcomes measured

Animal behavior patterns in the open field test
Functional state of the central nervous system (behavior-based assessment)

Limitations

Pilot experimental study
Sample size not reported in the abstract
Behavioral changes were also observed in the control group, suggesting possible chamber/background-related confounding
