EMF, Microwaves, and Bioeffects: What’s Real—and Where the Risks Actually Are

Electromagnetic fields (EMF) and microwaves are part of everyday life—power lines, Wi‑Fi, phones, radar, and kitchen microwaves all use some part of the spectrum. Most of the time, exposure is low. But at high enough power, radiofrequency (RF) and microwave energy can heat tissue and cause injury, and some effects (like “microwave hearing”) are real and repeatable.
