I am a scientist and was an editor of a major biological journal for several years. A portion of my basic research involved the use of very low intensity microwave radiation as a tool to study the function of biological organisms. This latter resulted in numerous published journal articles, book chapters and a book.

The authors of the Koyama et al journal article (1) present a rather peculiar exercise that they did. It appears that they wanted to gather some data and present it in a cell phone context as though it has relevance to cell phones. They lead off their abstract and also lead off their introduction talking about cell phones. Their extensive interpretations of their data are not relevant to cell phones and thus the article is misleading from a Public Health perspective.

It appears that they used a microwave oven frequency signal generator to produce an unmodulated signal. Such a signal is suitable for a study on heating tissue, not for a study which starts off discussing cell phones. Since cell phones use modulated signals, a cell phone relevant study requires a modulated signal and also requires a relevant carrier frequency. There is an enormous amount of published biological data that shows that the biological effects are different when one uses an unmodulated oven type signal instead of a modulated signal with a relevant carrier frequency. This is well known; it was even brought out in my book that was published 20 years ago (2).

There appear to be other major faults in their exercise that make it irrelevant to cell phone research and possibly other research. But since their energy frequency and modulation were inappropriate and this, in itself, discredits their discussing it in the context of cell phones, there is no need to discuss other faults in their exercise.
