ELECTRIC AND MAGNETIC FIELD INTENSITIES AND ASSOCIATED INDUCED BODY CURRENTS IN MAN IN CLOSE PROXIMITY TO A 50 KW AM STANDARD BROADCAST STATION
Authors not listed
Human bodies conduct measurable electrical currents when exposed to intense AM radio frequency fields near broadcast towers.
Plain English Summary
Researchers measured electric and magnetic fields near a 50,000-watt AM radio station and found extremely high exposure levels up to 300 volts per meter just 2 meters from the antenna. They also measured electrical currents flowing through human bodies in these fields, finding levels 260-290 times higher per unit of electric field than typical exposures.
Why This Matters
This study reveals the extraordinary EMF exposures that can occur near high-power radio transmitters. The electric field levels of 300 V/m measured just 2 meters from this 50 kW AM station are roughly 1,000 times higher than typical residential exposures from power lines or household appliances. What makes this research particularly valuable is the direct measurement of currents flowing through human bodies in these intense fields. The science demonstrates that theoretical calculations accurately predict real-world body currents, validating our understanding of how EMF interacts with human physiology. While few people work directly beside broadcast antennas, this data helps establish the biological mechanisms through which EMF affects the human body. The reality is that if measurable currents flow through people at these frequencies, similar but smaller effects likely occur from our everyday wireless devices operating at higher frequencies.
