Effects of Long-Term Exposure to L-Band (~2.0 GHz) High-Power Microwave on the Brain Function of Male Mice
Abstract
Overview
The ongoing concerns about electromagnetic fields (EMF) and their impact on the nervous system foster important research, such as this study which explores how prolonged exposure to high-power microwaves affects male mice.
Findings
- Study involved forty-eight male Institute of Cancer Research mice exposed to L-band high-power microwaves at approximately 2.0 GHz across various power densities (0.5, 1.0, and 1.5 W/m2).
- Brain functions were assessed after different exposure times, examining brain morphology and alterations at the cellular level through specialized staining methods (HE and TUNEL).
- Analysis also included evaluation of cholinergic markers, oxidative stress markers, and c-fos expression to determine potential mechanisms of brain damage.
- Significant findings indicate that exposure to the highest power density (1.5 W/m2) results in extensive hippocampal and cortical damage, characterized by cell apoptosis, cholinergic dysfunction, and oxidative injuries.
Conclusion
Exposure to L-HPM is potentially detrimental to the nervous system, with effects intensifying with higher power densities and longer exposure durations. The results highlight a clear link between long-term EMF exposure at high intensities and significant neural disruption.
