Microwave influence on the isolated heart function: I. Effect of modulation.
Pakhomov AG, Dubovick BV, Degtyariov IG, Pronkevich AN · 1995
View Original AbstractHeart tissue showed no unique electromagnetic effects from microwaves - only standard thermal heating responses at extremely high exposure levels.
Plain English Summary
Russian researchers exposed isolated frog heart tissue to microwave radiation at frequencies used by cell phones (915 and 885 MHz) to see if different pulse patterns affected heart function. They tested 400 different exposure combinations and found that heart changes only occurred when the microwaves generated enough heat to raise tissue temperature by 0.1-0.4 degrees Celsius. The heart effects were identical to those produced by conventional heating, suggesting the microwaves worked purely through thermal heating rather than any unique electromagnetic mechanism.
Study Details
Dependence of the microwave effect on modulation parameters (pulse width, duty ratio, and peak intensity) was studied in an isolated frog auricle preparation.
The rate and amplitude of spontaneous auricle twitches were measured during and after a 2 min exposu...
The experiments established that no regime was effective unless the average microwave power was high...
The data provide evidence that the effect of short-term microwave exposure on the isolated heart pacemaker and contractile functions depends on pulse modulation just as much as modulation determines the average absorbed power. These functions demonstrated no specific dependence on exposure parameters such as frequency or power windows.
