Microwave radiation affects the heart: Are the results real or are they due to interference?
In 2010, we published a paper that showed radiation from a cordless phone at 2.4 GHz affects the heart.
We heard from many people who acknowledged that they experience heart palpitations in certain environments and are unable to use mobile phones and be near cell phone antennas and Wi-Fi routers. We also learned that some students in schools with Wi-Fi experience a racing heart. Cardiologist, Dr. Stephen Sinatra, believes that those who have undiagnosed heart conditions may be particularly vulnerable to radio frequency radiation.
In the past we were concerned about the radiation from a microwave oven affecting heart monitors. Those heart monitors have been improved and are now shielded against radio frequency radiation. Our hearts are NOT shielded and our exposure to radio frequency radiation includes not only microwave ovens but mobile phones, cell phone antennas, wireless routers, smart meters, wireless computer games, blue tooth, and wireless baby monitors.
Our study was criticized and the claim was made that our results were due to electromagnetic interference (EMI).
EMI refers to disruption of an electronic circuit with an electromagnetic signal. A common example is the static you hear as you drive under high voltage transmission lines with your radio tuned to an AM station. The static on the radio is EMI.
In our experiment the radiation from the cordless phone may have affected the receiver, placed near the heart, creating spurious results. If this were the case, the signal would interfere each time but that did not happen. We were convinced our results were real (i.e. that we were recording changes in the heart rather than changes in the equipment) but the criticism of EMI was worth testing.
Was there a critical distance where the radiation from the cordless phone interfered with the equipment we were using?
So we designed an experiment to test for EMI. The results are in our new video. Click here to watch the video.
NOTE: There is an error in our previous video (2010). We refer to the cordless phone as a DECT phone. Technically DECT phones radiate between 1880 and 1930 MHz and the phone we used provides a signal at 2400 MHz. We do have DECT phones in North America but they operate at a different frequency than those in Europe. DECT 6.0 phones in U.S. and Canada operate at 1.9 GHz.
