To make sense of this large body of research, the Institute of Electrical and Electronic Engineers (IEEE) commissioned a review. From 2002 to 2004, each paper was re-read by at least three expert reviewers and critiqued for its applicability to the field of knowledge based on what we consider to be a good study with today's understanding of EM exposures. The results of this literature study netted 1411 publications that were considered to be the best work in the field; these were used to develop the latest edition of the IEEE safety standard: C95.1 -2005: IEEE Standard for Safety Levels with Respect to Human Exposure to Radio Frequency Electromagnetic Fields, 3 kHz to 300 GHz. Human exposure from cell phones and Amateur Radios alike is limited by FCC regulation to be lower than what the safety standard calls Maximum Permissible Exposure (MPE).
After 50 years and 1411 good scientific studies, what additional research could my correspondent and Dr Herberman know about that is vastly different? Certainly it was not research that was peer-reviewed, much less independently replicated. As scientists, they should know better than to base their scientific beliefs on such weak evidence. Granted, they are not experts in the field of electromagnetic bio-effects and are probably not aware of the wealth of knowledge that has been developed on this topic. But that's all the more reason that they should not overreact to anecdotal information that has not been subjected to scientific confirmation. Unfortunately, when the director of a large cancer institute makes such a proclamation, it is widely believed by people who know even less about the science than he does.
You could tell the good doc didn't have a clear understanding of what he was saying once he started warning about the dangers to others, of using cell phones in public places.
