Sir: The phone is a listening device. Before it transmits any signal, it must first 'hear' from the base station. If it cannot receive the base station signal, it will not transmit. The phone keeps 'listening' until it finds a base station with which to communicate.

Sir, Is there any possibility that your cell phone can go into a mode that it starts to send the registration signal continuously if you are in a “dead zone” (or you are surrounded by metal cabinets in all directions)? Can a cell phone malfunction and go into this mode?

Sir: The intermittent, registration communications between a mobile phone and its base station are milliseconds in duration at intervals of 5-10 minutes; minimal exposures.

This is very good information. But has any one done any study on the effects (if any) of cell phone fields on body internal organs? We know that cell phones make intermittent communications with cell towers even when they are not in use. Therefore, by simply carrying the cell phone with us, we are already exposed to the cell phone transmitting energy. Thus, it really does not matter if we are making long calls or short calls – we are being radiated 24 hours a day by just wearing the cell phone on the body. Thanks for addressing this.

This has been an interesting discussion. There is definitely a lot of interest in this subject. Our EMC chapter in Denver heard a talk on this subject from an EMC Society Distinguished Lecturer (Dr. Michel Ianoz) on July 26, 2004. This presentation addressed the subject of "Biological and Health Effects of Electromagnetic Fields" in a very organized and detailed manner using three approaches: * Calculation and measurement (engineers) * Biological effects (biologists and engineers) * Effects on health (medical doctors and statisticians) I was impressed with the variety of approaches that have been used to study the topic. He concluded that more studies needed to be done, but basically the health risk is at such a low level that it is difficult to evaluate. This contrasts greatly from the clear health risks of heavy smoking. But we should be concerned when we see that moss growth and other biological organisms are affected when exposed to electromagnetic energy. Certainly, the power limits and restrictions used today greatly reduce this concern. I have no problems using cell phones next to my ear for short calls, but I prefer to use an ear bud or the speaker phone function for longer calls to keep the phone farther >from my brain. By going to our chapter web site, you can see the record of the meeting (http://www.ewh.ieee.org/r5/denver/rock mountainemc/archive/2004/July/index.html) and the actual slides he presented (http://www.ewh.ieee.org/r5/denver/rock mountainemc/archive/2004/July/bioeffect.pdf).
