Microwave radiation at cell phone frequencies showed no effect on heart electrical conduction, even at exposure levels far above normal human limits.

Plain English Summary

Summary written for general audiences

Researchers exposed isolated frog hearts to 2.45 GHz microwave radiation (the same frequency used in microwave ovens and WiFi) for 2 hours at various power levels to see if it affected how electrical signals travel through heart muscle. They found no changes in the speed of electrical conduction through the heart tissue at any exposure level tested, including levels much higher than typical human exposure from wireless devices.

Study Details

The aim of this study is to investigate Character of the effect of microwave on conduction velocity of frog ventricular muscle.

Thirty-two frog hearts were divided into four groups and placed individually in temperature-controll...

No significant difference in conduction velocity was found between the control and the exposed group...
