Conditions of Strongest Electromagnetic Power Deposition in Man and Animals
Gandhi OP · 1975
Human bodies act like antennas at certain microwave frequencies, with neck absorption peaking at 300-400% above normal levels.
Plain English Summary
This 1975 study by Gandhi examined how microwave radiation is absorbed by human bodies and found that absorption peaks when the body's longest dimension equals about 0.4 times the wavelength of the radiation. The research revealed that the neck region experiences maximum power absorption, creating a resonance effect that increases absorption 3-4 times beyond what the body's physical size would predict.
Why This Matters
This foundational research established critical principles about how our bodies interact with microwave radiation that remain relevant today. Gandhi's finding that the human body acts like an antenna at specific frequencies, with peak absorption occurring in the neck region, helps explain why cell phone radiation exposure patterns matter so much. The study's discovery that resonance effects can amplify absorption by 300-400% beyond simple geometric predictions reveals why frequency matters as much as power levels. What makes this particularly concerning is that many of today's wireless devices operate at frequencies where human body resonance occurs. The neck region finding is especially relevant given how we hold phones and where we wear wireless earbuds and fitness trackers.
Exposure Information
Specific exposure levels were not quantified in this study.
