Plain English Summary
Researchers exposed mouse cells to microwave radiation at 2450 MHz to compare pulsed versus continuous waves. Pulsed microwaves caused more cellular damage and structural changes than continuous waves at identical power levels, suggesting that how EMF is delivered affects biological impact.
Why This Matters
This 1991 study reveals a critical finding that challenges the traditional 'dose makes the poison' approach to EMF safety standards. The research demonstrates that modulated (pulsed) microwave radiation produces more pronounced cellular effects than continuous waves at identical power levels. What makes this particularly relevant today is that virtually all modern wireless devices use pulsed signals - your smartphone, WiFi router, and Bluetooth devices all emit modulated RF radiation, not the continuous waves used in older safety testing. The study found cellular changes at SAR levels as low as 0.024 mW/g, which is well below current safety limits. This research supports the growing body of evidence suggesting that current safety standards, which focus primarily on heating effects from continuous wave exposure, may not adequately protect against the biological effects of the pulsed signals our devices actually emit.
