5G radiofrequency exposure at studied levels induced oxidative stress and cellular apoptosis in the auditory cortex through mitochondrial mechanisms without producing measurable changes in hearing or anxiety behaviors.
Plain English Summary
This study examined the effects of acute 3500 MHz (5G) radiofrequency electromagnetic radiation exposure on guinea pigs at various absorption rates over 72 hours. The researchers found that while hearing thresholds and anxiety-like behavior were not significantly affected, the exposure induced oxidative stress in the auditory cortex, triggered cell damage and apoptosis through mitochondrial pathways, and caused ultrastructural changes in a dose-dependent manner.
Why This Matters
The study employed a controlled animal model with multiple dosage levels to investigate mechanisms of potential RF-EMR biological effects. The findings suggest oxidative stress as a mechanistic pathway for RF-EMR effects at the cellular level, though the functional significance of the observed changes remains unclear given the absence of behavioral or auditory threshold alterations.
Exposure Information
Specific exposure levels were not quantified in this study.
