CHAPTER FIFTEEN Non-ionizing radiation: it is one of those curious idiosyncrasies of nature that, once you hear of a new writer or film star or even learn the meaning of an obscure word, it keeps cropping up again and again. Common sense tells us that it has always been around in books, newspapers and conversation, but after we are sensitized to a word or name we begin to see it all around us. Common sense may be right but in the privacy of our secret selves we may sometimes wonder if such coincidences have something magical about them. Carl Jung thought that there was and called these 'meaningful coincidences' synchronicity. In my case coincidence (or was it synchronicity) began when I first started to think about the biological effects of low-frequency (or non-ionizing) radiation. To my surprise, I learned that a laboratory was being built in the area to study the biological effects of radio and microwaves. Within a few weeks several articles on very low-frequency radiation turned up on my desk, and my friend, David Schrum in Sudbury, spoke to a scientist who was working in the same field. Things seemed to have advanced a great deal from that day, back in 1899, when Nikola Tesla discovered that the earth was alive with electrical power. Today a variety of natural electrical signals have been measured and characterized. In short, the first charts of that great electrical ocean first discovered by Nikola Tesla have been drawn up. Electrical fields arise from several different sources on earth. First there is the large voltage difference between the earth's surface and the upper atmosphere. Then there is the fluctuating difference in voltage between thunderclouds and the earth. In addition to these differences of electrical potential, there are waves of electromagnetic energy which are produced by weather fronts, thunderstorms and other atmospheric changes. Finally, 126
