C. F. Blackman et al. · 1980
Scientists exposed brain tissue to 147 MHz radio waves modulated at 16 Hz and found changes in calcium binding at a specific power level (0.83 mW/cm²). The effect only occurred within a narrow 'window' of field strength, and the width of this window changed depending on how many tissue samples were tested together.

Researchers developed a new technique to measure electric field strength inside microwave ovens using gas breakdown in small cells filled with helium. They tested this method against traditional power-based calculations and found it provided accurate, direct measurements without interfering with the microwave field.

Researchers exposed rabbits to 2450-MHz microwave radiation (the same frequency used in microwave ovens) for 23 hours daily over six months. The exposed rabbits showed significant changes in blood chemistry, immune function, and bone marrow compared to unexposed controls. These findings suggest prolonged microwave exposure can affect multiple biological systems.
